This video takes viewers to one of Nagasaki Prefecture’s noteworthy wartime relics: Mukyudo, a large air raid shelter located in Sasebo City. Constructed during World War II, Mukyudo is particularly unique because it was dug by local junior high students. With a capacity to shelter around 600 students, the sheer size of Mukyudo exceeds common expectations of air raid shelters in Japan.

The video provides a detailed walkthrough of the interior, beginning at the entrance and progressing to the main hall, which served as a central refuge area. The host also explores additional rooms, highlighting the hard work and resilience required to create such a large underground facility. These spaces reflect Japan’s wartime efforts and the community’s determination to protect its younger generation amidst air raids.

Mukyudo stands as a testament to both the hardships and solidarity experienced by locals during WWII. For travelers interested in Japan’s wartime history or those touring Nagasaki, a visit to Sasebo’s Mukyudo offers valuable insight beyond the usual tourist spots. Sasebo itself, located in the northwestern part of Nagasaki Prefecture, is also known for its scenic coastlines, naval base, and unique cultural blend influenced by its historical role as a port city.
