The names of 9,171 victims of the bombings of Osaka are inscribed in the ‘Garden of Time’.
The museum, inside Osaka Castle Park, uses objects and photographs to reconstruct the air raids that struck the city. The ‘Toki no Niwa’ (Garden of Time) holds the register of the dead and a plaque with the names identified over time: as of 2026 there are 9,171 out of an estimated total of about 15,000 victims.
