The lighthouse serves an important navigational role, and its nickname translates to "Guide to Seto." Thanks to its unique construction and vibrant crimson color, Setoshirube has become a symbol of the modern port in Kagawa Prefecture. It looks particularly striking in the evening and at night, when the glass blocks begin to emit a soft glow, earning the site recognition as one of "Japan's Three Great Night Lighthouses."

Located in the lively Sunport district, the lighthouse offers guests stunning panoramic views of the strait and passing vessels. It is not just a technical facility, but a true marvel of modern architecture, attracting both maritime enthusiasts and connoisseurs of unusual design from all over the world.

A stroll along the 540-meter promenade leading to Setoshirube offers a sense of complete harmony with the sea. Here, you can leisurely watch massive ferries and nimble boats connecting the Seto Inland Sea islands enter the port. Many travelers come here specifically to capture breathtaking sunsets, as the sun slowly dips into the water, painting the sky in incredible hues.

Photography enthusiasts and romantics should wait for dusk when the lighthouse illumination turns on. Its glass body glows with a warm red light, creating a unique atmosphere. It is an ideal location for relaxation, meditating to the sound of the surf, or an evening stroll after dining at local restaurants.

For those who prefer more grounded activities, the promenade is a popular spot for fishing or organizing small outdoor picnics. The proximity to the water and open horizons allow you to see the Inland Sea islands in detail and feel the invigorating sea breeze, making the walk pleasant at any time of year.

Reaching the Setoshirube lighthouse is extremely easy, as it is within walking distance of the city's main transportation hubs. From the central JR Takamatsu station, the walk takes only 5 to 15 minutes depending on your pace. The route leads through the modern Sunport district, offering pleasant views of the city's architecture and the sea.

For those traveling by car, the drive from the Takamatsu Chuo IC on the expressway takes about 20 minutes. Paid parking areas are available near the port, such as Kowan Park 1, which is just a stone's throw from the breakwater. You can also take a taxi from anywhere in the city center; the ride will be short and comfortable.

As Takamatsu Port is a key transport hub, the lighthouse is easily accessible if you are arriving by ferry from neighboring islands. The landmark's coordinates make it easy to find on a map, and its proximity to historical castle ruins makes it a convenient stop on a comprehensive tourist route.

Despite its futuristic look, the Takamatsu Red Lighthouse is closely tied to the region's maritime history. It became the world's first lighthouse with a structure made entirely of transparent glass blocks. In 2016, the Japan Romantist Association and the Nippon Foundation included it in the prestigious list of "Japan's Three Great Night Lighthouses," and in 2019, it received official status as a "Japan Night View Heritage" site.

The lighthouse's location in the Sunport district is no accident—this area has historically been the city's gateway to the sea. Nearby are the ruins of Takamatsu (Tamamo) Castle, built in 1590 by Ikoma Chikamasa. This castle is famous for being one of the country's three "water castles," with moats that connect directly to the sea. The modern glass lighthouse creates an interesting visual contrast with the ancient defensive walls.

Today, Setoshirube is seen not just as a functional navigational aid but as a symbol of the port's revitalization. While maintaining maritime traditions, it brings elements of modern art and innovation to the city's skyline. Tamamo Park, surrounding the castle ruins with its Ushitora and Tsukimi turrets, completes this landscape, bridging the samurai era and the present day.

Typically, visitors need 30 to 60 minutes to leisurely walk to the end of the breakwater, take photos, and enjoy the view of the Red Lighthouse. This is plenty of time to soak in the seaside atmosphere and examine the unique glass structure up close.

If you plan to combine your walk to the lighthouse with a visit to the nearby castle ruins in Tamamo Park, you should budget about 1.5–2 hours in your schedule. This will allow you to immerse yourself in the region's history and appreciate the port's modern architectural designs without rushing.

One of the main features of the Takamatsu Red Lighthouse is its accessibility: it is open to visitors 24 hours a day, seven days a week. This allows guests to choose the most suitable time for a visit—whether it's early morning for the sunrise or late evening to see the glowing body of the lighthouse.

Access to the breakwater is free and open, so there are no operating hours or breaks. However, tourists are advised to check the official port website in case of extremely poor weather conditions, as access to the far end of the promenade may be temporarily restricted for safety during heavy storms.

A visit to the Setoshirube lighthouse can easily be turned into a full day of sightseeing, as the Takamatsu Port area is packed with interesting sites. The combination of sea views and architectural monuments within walking distance makes this a must-visit for any traveler.

Near the port, you will find both quiet park areas and modern cultural centers, allowing you to create a rich and varied itinerary. Below are attractions located within a few kilometers of the lighthouse:
