Harrowing Perfect Rainy Day Activity - A visit here is very harrowing, but we are so glad we spent our rainy day morning visiting such a historical piece of the Battle of Okinawa. It does not take much time to explore, but is well worth your time no matter what level of history buff you may or may not be!

Underground WW II Facility - This tunnel complex in Okinawa was built in 1945 and opened to the public in March 1970 as a reminder of the horrors of war and to promote peace. The headquarters is at tunnel approximately 65+ feet deep and 1476 feet long and served as the Japanese Navy headquarters and an underground air-raid shelter. As many as 4,000 soldiers lived, worked, and hid here during the war until they and the Rear Admiral Minoru Ota committed suicide in June 1945 rather than surrender. After walking down a steep flight of stairs into the tunnels, arrows point to stops on the circular route. The route pathways take you to several rooms used by the navy staff including the staff officers’ and petty officers’ room, the signal and medical rooms, and the commanding officer’s room. Be on the lookout for bullet holes and shrapnel from grenades. In fact, one of the rooms has a sign that states “wall riddled with a hand grenade when committee suicide”. Before leaving the facility (or before going into the tunnels like we did), be sure to stop at the single-room museum and look at the exhibits including a brief story of the Battle of Okinawa, uniforms, weapons, letters, notebooks, and a Japanese flag. The museum is home to Commanding Officer Minoru’s telegram he wrote before committing suicide. Recommend visiting this headquarters. Entrance fee is 450 yen ($2.90 USD) per adult in 2024.

Former Navy Underground Bunker - Very good value tickets and easy to find site. Very well presented and informative exhibition followed by an interesting walk through the tunnels.

A Great War Sites - The Navy Underground Headquarters was a great and unique experience. The museum provides a lot of information on the Battle of Okinawa in both Japanese and English. They also have a collection of historical items found in the tunnels on display. My friends and I enjoyed are time here and we felt it was very educational. I would highly recommend this site to anyone looking to visit a few historical sites while in Okinawa.

Moving.. - Very solemn location. Informative and moving. War is horrible. Peace in the world .. now more than ever. My father served in WWII on Okinawa the horrors of the war led him to becoming a pacifist.

This place is worth the visit - highly recommend. - We were on a cruise & had the day in this area & decided to see the underground headquarters. We caught a taxi & so worth the expense to visit this place and have plenty of time to see it. The entry fee was very cheap. There are taxi that comes & goes & was able to be taken back to our ship. Highly recommend to visit

Former Navy HQ - It was very informative and interesting. The staff were pleasant. The tunnels lead to different areas of the headquarters. If you're very tall, you'll need to bend your head a few times while in the tunnel. It was an overall good experience.

The sad signal from the former naval headquarters - I think the number of Japanese who experienced the war is decreasing, and the memories are fading. I went to Okinawa to learn about what it was like at the time, as it was a fierce battlefield and a place that experienced a painful past. I want the whole country to continue to talk about the horrific events of war, from the struggles at headquarters to do something, to the suffering of military personnel and their families, to the various circumstances that drove them to the brink, and to leave them for future generations.

A piece of history - Very affordable. Many signs in English. Makes you think of the horrors of war and the plight of Okinawa’s people to be drawn into conflict.

Visit was interesting with history of Okinawa at world war 2. If you like history it’s will be a good visit. - We drove to the venue , public parking is available and easy assess to the place. It’s was an educational & interesting visit.
