Oki Islands

Discover the Oki Islands, a captivating archipelago located in the Sea of Japan, roughly 40 to 80 kilometers north of the Shimane Peninsula. Known for their dramatic coastal scenery and deep cultural roots, these islands offer a serene escape from the hustle and bustle of mainland city life. With a population of around 20,000 residents, the islands maintain a close-knit community atmosphere where traditional customs are proudly preserved.

The archipelago consists of four main inhabited islands and numerous smaller ones, collectively recognized as a UNESCO Global Geopark due to their unique geological evolution. The landscape is defined by rugged cliffs, emerald green waters, and lush vegetation. Visitors are often struck by the fascinating history of the Oki Islands, which once served as a place of exile for emperors and nobles, leaving behind a legacy of aristocratic culture and ancient shrines that can still be explored today.

Nature enthusiasts will be drawn to the breathtaking Kuniga Coast on Nishinoshima, featuring towering cliffs and stone arches, as well as the iconic Candle Island off the coast of Dogo, which appears to light up like a candle at sunset. Beyond the scenery, the islands are famous for their unique local traditions, such as Bull Sumo, a spirited event that has entertained locals for centuries. Whether you are hiking through ancient cedar forests or enjoying fresh seafood, the Oki Islands promise an unforgettable adventure.

The climate in the Oki Islands is influenced by the surrounding Sea of Japan, resulting in distinct seasonal changes throughout the year. Winters are generally cool and damp, with January seeing average temperatures of 6.7°C and a high frequency of precipitation, recording roughly 21 wet days. Conversely, summer brings warmth, with August peaking at an average of 27.1°C. Travelers planning a trip should consult the detailed guide to the weather in Oki Islands to pack appropriately for the specific month of travel.

Spring and autumn provide mild and comfortable conditions for sightseeing. May is particularly pleasant, with an average temperature of 17.4°C and fewer rainy days compared to the winter months. October offers a similar average of 18.8°C, gradually cooling down as the islands approach the end of the year. These transitional seasons are often considered excellent times for hiking and exploring the dramatic coastlines.

Overall, expect warm summers with occasional rain and cool winters characterized by frequent precipitation days. While temperatures rarely drop to freezing extremes, the high number of wet days in December and January suggests that waterproof gear is essential for winter visits.

Beyond the scenic coastlines and geological wonders, the Oki Islands harbor a treasure trove of historical and ecological curiosities that often surprise visitors. Here are some fascinating details that make this archipelago truly unique:

• A Botanical Paradox: The islands are home to a rare ecological phenomenon where sub-alpine plants typically found in northern Japan grow alongside warm-temperate vegetation from the south. This unusual coexistence is created by the intersection of the warm Tsushima Current and cold winds from the Asian continent.

• Ancient Obsidian Factory: Long before recorded history, the Oki Islands were a primary source of high-quality obsidian. Archaeological evidence suggests that obsidian mined here over 30,000 years ago was traded extensively, reaching as far as the Korean Peninsula and the Russian mainland.

• The Makihata System: To overcome the challenge of limited arable land on steep terrain, islanders developed a unique four-field crop rotation system known as Makihata. This medieval practice involved rotating between crops and grazing cattle to naturally fertilize the soil, shaping the distinct pastoral landscapes seen on the islands today.

• Aristocratic Dialect: Due to the historical exile of emperors and high-ranking nobles to the islands, the local dialect retains elegant, courtly expressions. These linguistic traces of the ancient capital's aristocracy have been preserved in isolation, differing significantly from typical rural dialects in the region.

Reaching the Oki Islands is an exciting start to your journey, typically involving a combination of air travel and ferry crossings from the Japanese mainland. For travelers looking for comprehensive route options and schedules, you can read more about how to get to Oki Islands to plan your trip effectively. The archipelago is well-connected to several major transport hubs in the Shimane and Tottori prefectures.

The most direct way to arrive is by flying into Oki Airport (OKI), which is conveniently located on Dogo, the largest of the islands. It is situated just 3.4 km from the town center, making it a very accessible entry point. A taxi or bus ride from the airport to the main areas takes approximately 25 minutes. Although it is a smaller regional airport with an annual passenger traffic of around 127,000, it provides vital links to mainland cities like Osaka and Izumo.

Alternatively, many visitors fly into larger airports on the mainland and then take a ferry to the islands. Izumo Airport (IZO) in the city of Izumo is a popular choice, located about 97 km away. From here, travelers can transfer to a port for the sea crossing; the total travel effort, including ground transport, is estimated to take roughly 2 hours and 45 minutes. Another convenient option is Miho Airport (YGJ) in Yonago, approximately 79 km from the islands. This airport handles nearly half a million passengers annually and serves as a gateway to the region, with an estimated travel time of about 2 hours and 20 minutes to reach the islands via connection.

For clarity, here is a summary of the main airports serving the region:

The Oki Islands offer a remarkable blend of dramatic geological formations and ancient spiritual sites, making them a paradise for nature lovers and history buffs alike. The archipelago’s isolation has preserved not only its unique ecosystem but also its distinct cultural heritage. From towering sea cliffs to sacred shrines hidden in the forests, the attractions here provide a deep connection to the raw beauty of the Sea of Japan.

One of the most iconic natural wonders is the Kuniga Coast on Nishinoshima Island. This stretch of coastline is famous for the breathtaking Matengai Cliff, which rises a staggering 257 meters above the sea, making it one of the highest sea cliffs in Japan. Visitors can enjoy a scenic hiking trail that leads from the top of the cliff down to the shore, passing by grazing cows and horses in open pastures. At the bottom, the Tsutenkyo Arch, a massive rock bridge formed by sea erosion, offers a stunning photo opportunity and a testament to the power of nature.

For a magical evening experience, a visit to Candle Island (Rosoku-jima) off the coast of Dogo Island is a must. This distinct rock formation rises about 20 meters from the water and resembles a candle. The main attraction here is the sunset sightseeing boat tour; skilled captains position the boat perfectly so that the setting sun sits atop the rock's tip, creating the illusion of a lit candle. It is a fleeting but unforgettable moment that has become a symbol of the Oki Islands.

Those interested in the spiritual history of the region should explore the Tamawakasu-mikoto Shrine on Dogo Island. As the guardian shrine of the Oki region, it holds significant historical importance and features a unique architectural style known as Oki-zukuri. Within the shrine grounds stands the majestic Yao-sugi, a Japanese cedar tree estimated to be over 2,000 years old. Supported by props to hold up its ancient branches, the tree creates a solemn and mystical atmosphere that captivates visitors.

Another scenic highlight is the Shirashima Coast, located at the northernmost point of Dogo Island. The name, meaning "White Island," comes from the striking white rhyolite rock formations that contrast beautifully with the deep blue of the ocean and the green of the pine trees. A lookout point offers panoramic views of the numerous islands scattered across the sea, and a walking trail allows tourists to immerse themselves in the peaceful, rugged landscape.

The culinary landscape of the Oki Islands is a direct reflection of its rich natural environment, offering a "sea-to-table" experience that is hard to rival. Being an archipelago in the Sea of Japan, the local diet is heavily centered on fresh seafood, but the islands are also home to unique agricultural traditions. Visitors can expect hearty, unpretentious meals where the quality of the ingredients takes center stage, ranging from premium beef to distinct noodle dishes found nowhere else in Japan.

One of the most prized delicacies here is the Iwagaki Oyster, or rock oyster. Unlike typical oysters, these are massive in size and are harvested deep in the ocean during the spring and summer months. They are known for their creamy texture and rich flavor, often enjoyed raw with a squeeze of citrus to highlight their freshness. Another seafood staple is the Sazae (turban shell), which is caught in abundance around the rocky shores. You will often find it grilled in its shell or served in a savory rice bowl known as Sazae-don, a comfort food favorite among locals.

For meat lovers, Oki Beef is a gastronomic treasure that must be experienced. The cattle on the islands are raised in open pastures rich in minerals from the sea breeze, resulting in high-quality meat with exquisite marbling and tenderness. Because production is limited, Oki Beef is considered a rare luxury, often served as steak or shabu-shabu in high-end local establishments and ryokans.

Noodle enthusiasts should try Oki Soba, a traditional dish with a history dating back centuries. Unlike the smooth, long buckwheat noodles found on the mainland, Oki Soba is made from 100% buckwheat flour without binding agents, giving it a unique, brittle texture and shorter length. It is typically served in a flavorful broth made from roasted flying fish (ago) or mackerel, and is eaten with a spoon rather than slurped, often topped with local roasted nori and condiments.

To accompany these dishes, the local sake is an excellent choice. The islands are blessed with ultra-pure water sources, which are essential for brewing high-quality rice wine. Oki Homare is the representative local brand, offering a crisp and dry profile that pairs perfectly with the region's rich seafood. Dining in the Oki Islands is generally a relaxed affair; whether you are eating at a small portside eatery, a family-run izakaya, or enjoying a kaiseki feast at your inn, the atmosphere is warm and welcoming.

Preparing for a trip to the Oki Islands requires a bit of foresight due to their remote nature and distinct island lifestyle. These practical tips are designed to help you navigate the archipelago smoothly, ensuring you can focus on the breathtaking scenery and warm local hospitality without any logistical hiccups.

1. Clothing and Gear: The weather in the Sea of Japan can be changeable, especially along the coast. It is wise to bring layers, including a windbreaker and a waterproof jacket, regardless of the season. Since exploring the islands often involves hiking rugged trails like the Kuniga Coast, sturdy and comfortable walking shoes are essential. Also, pack slip-on shoes, as you will frequently need to remove footwear when entering traditional inns, shrines, and some restaurants.

2. Transportation: While there is a local bus network, services can be infrequent and may not align perfectly with sightseeing needs. Renting a car is the most efficient way to explore the islands at your own pace. Alternatively, electric assist bicycles (e-bikes) are available for rent at tourism associations near the ports and are a fantastic way to see the sights. Remember to check the ferry schedules between islands in advance, as they can be affected by weather conditions.

3. Finances: The Oki Islands are still largely a cash-based society. While some larger hotels and souvenir shops accept credit cards, many smaller guesthouses, restaurants, and ticket counters do not. Ensure you withdraw sufficient Japanese Yen (JPY) before leaving the mainland. If you run low, look for Japan Post Bank ATMs, which typically accept international cards, though they may not be available 24/7 in smaller villages.

4. Health and Safety: The islands are incredibly safe, but medical facilities are limited compared to big cities. Pharmacies are generally not open late or on weekends, so bring a sufficient supply of any prescription medications or basic remedies (painkillers, motion sickness pills for the ferry) with you. In an emergency, dial 119 for an ambulance or fire department.

5. Communication: English is not widely spoken outside of major tourist information centers. It is highly recommended to have a translation app downloaded on your phone. Renting a pocket Wi-Fi or purchasing a SIM card at a major airport on the mainland (like Osaka or Tokyo) before arriving is crucial, as finding these services on the islands can be difficult.

6. Local Etiquette: Politeness is paramount. A small bow is the standard greeting. When visiting shrines, respect the sacred atmosphere by speaking quietly and not blocking the path for others. If you are staying in a minshuku (family-run guesthouse), try to adhere to the scheduled meal and bath times, as these establishments are often run by small families.

7. What to Avoid: Do not enter fenced pastures or open gates without permission. The islands use a traditional rotation grazing system, meaning cows and horses often roam freely in designated areas; disturbing the animals or letting them out can cause significant issues for local farmers. Additionally, avoid being late for ferries, as they depart strictly on time.

8. Additional Tip: Visit the Tourism Association counters located at the ferry terminals upon arrival. The staff are incredibly helpful and can provide up-to-date maps, bus schedules, and sometimes even discounted "passport" tickets for multiple attractions or ferry rides, which can save you money during your stay.

By keeping these practicalities in mind, you will be well-equipped to enjoy the serene beauty and unique culture of the Oki Islands. A little preparation goes a long way in this rural paradise, allowing you to relax and immerse yourself fully in the island experience.

Nightlife in the Oki Islands offers a distinct departure from the neon-lit, bustling districts of Japan's major metropolises. Instead of thumping nightclubs and sprawling entertainment complexes, the evenings here are defined by a warm, intimate atmosphere centered around food, drink, and conversation. The experience is deeply local, revolving primarily around izakayas (Japanese-style pubs) and traditional snack bars, where visitors can mingle with residents and enjoy the slow-paced island life.

The most active area for evening entertainment is found in Okinoshima Town on Dogo Island, particularly around the Saigo Port district. This area serves as the commercial heart of the archipelago and hosts a cluster of dining establishments and small bars. On the smaller islands like Nishinoshima, the nightlife is even more subdued, often concentrated near the main ferry terminals such as Beppu Port, where a handful of welcoming eateries and bars keep their lights on after sunset. The vibe is casual and friendly, with a "come as you are" dress code that welcomes hikers and travelers alike.

For those looking to enjoy local flavors and drinks, Ajitomi on Dogo Island is a well-regarded establishment known for serving high-quality Oki beef and local sake in a relaxed setting. It is a great place to start the evening with a hearty meal and premium drinks. Another popular type of venue in the Saigo area is the local "Snack Bar"—small, retro establishments run by a "mama-san" where singing karaoke and chatting with the staff is the main event. Venues like Hachinoki also offer a cozy environment to sample fresh seafood dishes accompanied by the island's signature Oki Homare sake.

Practical advice is essential for a smooth night out in this rural setting. Most venues operate on a cash-only basis, so ensure you have sufficient yen before heading out, as ATMs may be scarce or closed at night. Since public transport stops running in the early evening, you will rely on taxis or walking to get back to your accommodation. It is advisable to ask your restaurant or hotel to call a taxi for you (such as Oki Taxi), as flagging one down on the street can be difficult. The streets are incredibly safe for night walks, though they can be dimly lit, so carrying a small flashlight or using your phone light is a good idea.

During the daylight hours, entertainment shifts towards cultural and educational experiences rather than commercial amusement. Visitors can explore the Oki Islands Global Geopark Museum near Saigo Port to understand the region's geological significance through interactive exhibits. For a more traditional experience, small local history museums and craft workshops offer a glimpse into the island's heritage and the unique Makihata farming system. While there are no large theaters or amusement parks, the natural landscape itself serves as a vast playground for kayaking, fishing, and scenic tours.

The Oki Islands are not just a geological wonder but a living museum where nature and history intertwine seamlessly. As part of the Daisen-Oki National Park, the entire archipelago serves as a vast outdoor sanctuary, while its indoor institutions preserve the legacy of emperors and the unique lifestyle evolved in isolation.

For those seeking dramatic natural landscapes, Sekiheki (Red Cliff) on Chiburijima is a standout destination. Unlike the grey basalt found elsewhere, this coastline features striking red rock surfaces created by volcanic eruptions millions of years ago. The contrast between the rusty red cliffs, the deep blue sea, and the green vegetation creates a vivid color palette that is perfect for photography. Another significant green space is the area around Mt. Takuhi on Nishinoshima. A hike to the summit takes visitors through primeval forests and offers panoramic views of the caldera scenery, rewarding trekkers with a visit to the Takuhi Shrine, partially tucked into a cave near the peak.

To understand the forces that shaped these islands, a visit to the Oki Islands Global Geopark Museum in Okinoshima Town is essential. Located conveniently near the ferry terminal, this facility serves as the gateway to the Geopark. It features projection mapping, interactive exhibits, and geological samples that explain how the islands separated from the mainland, creating their unique ecosystem. For a dive into cultural history, the Gotoba-in Museum on Nakanoshima (Ama Town) is dedicated to Emperor Go-Toba, who was exiled to the island in the 13th century. The museum displays artifacts, literary works, and historical documents that illuminate the life of the exiled aristocracy and their influence on local culture.

The islands are also dotted with profound historical landmarks. Oki Shrine in Ama Town is a prominent site built to enshrine the spirit of Emperor Go-Toba. It is known for its serene atmosphere and the beautiful cherry blossoms that bloom along its approach in spring. On Nishinoshima, history buffs can visit the ruins of Kuroki-gosho, the temporary imperial residence of Emperor Godaigo, another exiled ruler. Although modest in appearance, the site holds immense historical weight, marking a pivotal moment in Japanese imperial history.

For a truly authentic experience, consider renting a bicycle to explore the smaller farming villages on the Dozen islands. The pace of life here is incredibly slow, and you might stumble upon small, unmanned roadside stalls selling fresh local vegetables or citrus fruits—a charming testament to the local community's trust and hospitality.

Navigating the Oki Islands requires a shift in mindset from the rapid-transit systems of major metropolises. As a remote archipelago, there are no subways, trains, or trams here. Instead, the public transport network relies entirely on a combination of local route buses for land travel and an extensive ferry system that connects the four inhabited islands. For tourists, understanding how to coordinate these two modes of transport is key to a smooth journey.

The local bus network is the primary way to get around on land for those without a vehicle. Each of the main islands—Dogo, Nishinoshima, Nakanoshima, and Chiburijima—operates its own municipal bus service. These buses generally connect the ferry ports to major villages, hospitals, and key tourist attractions. However, frequencies can be low, with some routes running only a few times a day. On Dogo Island, the network is slightly more extensive, covering the town center and outlying coastal areas, but planning your day around the timetable is still essential.

Given the geography, inter-island ferries function much like a metro system would in a big city, serving as the essential link between the islands. There are two main types of vessels: the large car ferries, which are slower and more stable, and the high-speed "Rainbow Jet" hydrofoils, which are faster but more expensive. There is also a smaller, frequent inter-island ferry specifically connecting the three islands of the Dozen group (Nishinoshima, Nakanoshima, and Chiburijima). These boats are lifelines for the locals and offer scenic rides for visitors.

The payment system on the Oki Islands is traditional and relies heavily on cash. Unlike on the mainland, IC cards like Suica or Pasmo are generally not accepted on local buses or ferries. When boarding a bus, you should take a numbered ticket (seiri-ken) from the machine by the door. A display at the front of the bus will show the fare corresponding to your ticket number. When you arrive at your destination, drop the exact change and your ticket into the box next to the driver. If you do not have exact change, the fare box usually has a machine that can break 1,000 yen bills and 500 yen coins.

For tourists planning to use the bus extensively, unlimited ride passes are a great value and a convenient option. "1-Day" or "2-Day" bus passes are often available for purchase at the tourist information centers located inside the ferry terminals. These passes allow you to hop on and off freely without worrying about carrying small change. Be sure to buy these upon arrival at the port, as they cannot usually be purchased on board the bus itself.

While public transport is reliable, it may not reach every secluded scenic spot or trailhead. Consequently, rental cars are the most popular alternative and are highly recommended for maximizing your time. Rental agencies are located near the ports and the airport. For those who prefer a slower pace, electric-assist bicycles (e-bikes) are widely available for rent at tourism associations. Given the hilly terrain of the islands, the electric assist is a game-changer, allowing you to breeze up slopes to reach observation decks. Taxis are available but can be expensive for long distances and typically need to be called in advance, as they do not cruise for passengers.

A final piece of practical advice: always double-check the weather conditions. Strong winds and high waves can lead to the cancellation of ferry services, particularly the fast hydrofoils. Bus schedules generally align with ferry arrivals and departures, but it is wise to confirm the return times, as services often stop running in the early evening. Tourist information staff at the ports are excellent resources for English timetables and current operating status.

Finding a place to stay in the Oki Islands is an opportunity to immerse yourself in traditional Japanese hospitality. Unlike the sprawling resort complexes found in major cities, the accommodation landscape here is defined by intimate, family-run establishments that offer a warm and personal connection to the local culture. Options range from rustic guesthouses to comfortable modern hotels, primarily concentrated near the ferry ports of the four inhabited islands.

The most authentic way to experience the islands is by staying in a ryokan (traditional inn) or a minshuku (family-style guesthouse). These lodgings are widely available across the archipelago and typically feature tatami-matted rooms where guests sleep on futons. A stay here almost always centers around the cuisine; hosts take immense pride in serving elaborate dinners showcasing fresh local seafood, such as Iwagaki oysters and white squid. It is highly recommended to book a "half-board" plan that includes both dinner and breakfast, as restaurants in the smaller villages often close early or may be scarce.

For travelers preferring Western-style amenities, such as beds and private en-suite bathrooms, options are available but are mostly found on Dogo Island, particularly in Okinoshima Town near Saigo Port. These hotels provide a convenient base with standard comforts like Wi-Fi and easy access to transport links. While they may offer less cultural immersion than a minshuku, they are practical for those who prioritize privacy and flexibility in their schedule.

Choosing the right location is key to a smooth trip. Dogo Island offers the largest variety of accommodations and is the best choice for those arriving by air or seeking proximity to supermarkets and services. In contrast, the Dozen Islands (Nishinoshima, Nakanoshima, and Chiburijima) offer a quieter, more secluded atmosphere. Accommodation here is often smaller and fills up quickly, especially during the peak summer season. On the smallest island, Chiburijima, the number of guesthouses is very limited, so reserving months in advance is essential.

A few practical tips will ensure a hassle-free stay. Many smaller accommodations in the Oki Islands operate on a cash-only basis, so it is vital to bring sufficient Japanese Yen to cover your lodging costs. Check-in times at family-run places can be strict, often requiring arrival by late afternoon to ensure dinner service. Finally, amenities like toothbrushes and towels are usually provided, but bringing your own toiletries is a good practice when staying in budget-friendly minshukus or cabins.

For those looking to explore the surroundings, Oki Islands serves as an excellent base for day trips to several interesting nearby locations. While the archipelago itself offers days of exploration, the fast ferry and flight connections make it possible to visit neighboring islands or even reach the mainland for a short excursion or the next leg of your journey.

One of the most accessible destinations is Ama, located on Nakanoshima Island within the Dozen group. Just a short ferry ride away, Ama is famous for the Oki Shrine, dedicated to the exiled Emperor Go-Toba. The town offers a peaceful atmosphere with beautiful coastal scenery, including the Akiya Coast with its distinctive red cliffs and heart-shaped rocks. It is an ideal spot for visitors who want to experience the different vibes of the Oki archipelago without traveling far.

On the mainland, Matsue is a cultural highlight known as the "City of Water." Accessible via the high-speed "Rainbow Jet" ferry, it is home to one of Japan's twelve original castles, Matsue Castle. Visitors can take a boat tour around the castle moat or watch the spectacular sunset over Lake Shinji. As a major transport hub for the region, it combines rich history with modern conveniences.

Further west lies Izumo, a city steeped in mythology and home to Izumo Taisha, one of Japan's oldest and most important Shinto shrines. It is said that all the gods of Japan gather here once a year. The city offers a profound spiritual experience and is also a gateway to the region via its airport, making it a significant stop for travelers interested in Japanese folklore and history.

These nearby destinations offer a glimpse into the diverse culture and landscapes of the region, ranging from sacred shrines and historic castles to scenic coastal towns.

Shopping in the Oki Islands offers a quaint and authentic experience that contrasts sharply with the neon-lit retail districts of mainland Japan. Instead of high-end fashion boutiques or sprawling department stores, visitors will find a selection of small, locally-run shops that focus on regional specialties. The shopping scene here is deeply connected to the islands' natural resources, with a strong emphasis on fresh seafood products, traditional crafts, and daily necessities that sustain the local community.

The primary hub for shopping is located in Okinoshima Town on Dogo Island, particularly in the area surrounding Saigo Port. As the main entry point for most travelers, the ferry terminal itself houses a well-stocked souvenir shop offering a wide range of local goods. The streets immediately adjacent to the port feature a few specialty stores where you can find traditional Japanese confections and local handicrafts. On the smaller islands like Nishinoshima, shopping is even more low-key, often centered around the ferry terminals such as Beppu Port, which serve as convenient spots to pick up gifts before departure.

Travelers should not expect Western-style shopping malls in this remote archipelago. The closest equivalent is the Sunterrace Shopping Center located in Okinoshima Town. This facility functions as a community lifeline, housing a supermarket, a 100-yen shop, and stores selling clothing and household goods. It is the most reliable place to purchase groceries, replenish travel supplies, or buy items you may have forgotten to pack. There are also a few large drugstores on Dogo Island that sell cosmetics, snacks, and medical supplies.

For a taste of local life, visiting a direct sales market (chokubai-jo) is highly recommended. Anki Ichiba in Okinoshima is a popular spot where local farmers and fishermen sell their fresh harvest directly to consumers. Here, you can find seasonal vegetables, freshly caught fish, and homemade processed goods. While fresh produce may not be suitable for long-distance travel, these markets are excellent for finding vacuum-packed seafood delicacies or dried goods that offer a true flavor of the islands.

When it comes to souvenirs, the Oki Islands have several unique offerings. The region is famous for its high-quality obsidian, and visitors can purchase beautiful accessories, seals, and ornaments carved from this black volcanic glass. Food-related gifts are also very popular; look for bottles of Oki Homare (the local sake brewed with pure island water), packs of ago-dashi (soup stock made from flying fish), or retort pouches of rich Oki Beef curry. Another local favorite is processed sazae (turban shell), often sold as a savory paste or boiled in soy sauce.

Business hours on the islands are generally shorter than in big cities. Most souvenir shops and small retailers open around 9:00 AM and close by 6:00 PM or 7:00 PM. Supermarkets and drugstores may remain open until 8:00 PM or 9:00 PM. It is critically important for tourists to carry sufficient cash (Japanese Yen). While the main ferry terminal shops and larger supermarkets usually accept credit cards, many smaller vendors, craft shops, and markets operate strictly on a cash-only basis.

Tax-free shopping is quite limited in the Oki Islands compared to major tourist destinations like Tokyo or Osaka. Most local shops are not equipped to process tax refunds for international tourists. Visitors should generally expect to pay the standard consumption tax on their purchases and plan their budget accordingly.
