What to Do

Visiting the Former Japanese Navy Underground Headquarters in Tomigusuku offers a unique opportunity to immerse yourself in history. The main focus of exploration is the restored underground tunnels, spanning about 300 meters. Here, you can walk through the corridors and look into various rooms that once served as a command center. These include the commander's room, the operations room, and the medical office, each providing insight into how the headquarters functioned during its active period.

Above ground, at the top of the hill, sits a memorial dedicated to the historical events associated with this site. It serves not only as a monument but also as a landmark for visitors. Additionally, you will have the chance to examine a layout of the underground structures. This will help you better understand the scale of the construction and learn about its unique building process—the bunker was dug by hand using only simple tools, which is impressive in itself.

For those who want to study the history of this site more deeply, there is a museum exhibition on the complex grounds. The museum displays materials and information detailing the events related to the underground headquarters and its significance. It is an excellent addition to the tunnel tour, providing a more complete and meaningful understanding of this historical location.

Getting There

Reaching the Former Japanese Navy Underground Headquarters in Tomigusuku is quite straightforward, especially if you are in the Naha area or near Okinawa Airport. One of the most convenient ways is by public transport. Buses depart regularly from the Naha Bus Terminal/Asahibashi towards the site.

Look for routes #55 or #98 heading towards Tomigusuku Minami. The bus ride takes approximately 15 minutes and costs about 260 yen. After getting off at the stop nearest the headquarters, be prepared for a short walk—a climb uphill that takes another 15 minutes. Since finding the entrance to the bunker on your first try might be tricky, it is recommended to have a map or use a navigation app.

A good landmark is the memorial located at the top of the hill—the entrance to the underground facility is situated right next to it. Given the attraction's proximity to Okinawa Airport, some travelers choose to visit the headquarters just before their flight, which is also a convenient option.

History & Facts

The Former Japanese Navy Underground Headquarters in Tomigusuku is a significant historical site built in 1944. An incredible fact is that this complex system of underground structures was created entirely by hand. Workers used only primitive tools like hoes and pickaxes, making its construction an impressive engineering feat for its time, especially under wartime conditions.

The history of this site is marked by tragic events. It was within these bunker walls that Japanese commander Minoru Ota, along with many of his officers, chose to commit ritual suicide, known as seppuku. Reports suggest that Admiral Ota ended his life by detonating a hand grenade. To honor these dramatic events and those who lost their lives, a memorial monument was erected at the entrance to the complex, serving as a reminder of the human cost of war.

After the end of the conflict, the underground headquarters remained abandoned and untouched for a long time. It wasn't until 1970 that the decision was made to restore it and turn it into a memorial complex open to the public. During restoration work, the remains of approximately 2,400 people were discovered. Today, the former Navy headquarters functions as a museum and historical monument, allowing visitors to touch the past and learn more about the events that unfolded here.
