Tokiwaso, that was once located at Shiinamachi (current Minami-Nagasaki) in Toshima City, is a legendary apartment building where great modern manga artists including Tezuka Osamu lived together and spent their youth there. The original Tokiwaso was demolished in December 1982, but it was rebuilt as a manga museum thanks to the great support from many people. We do our best as the initiator of manga and anime culture to transmit the culture to the next generation. We would like sincerely to thank all donors, contributors and cooperators for helping us to open the museum and we would also greatly appreciate your further guidance and encouragement.
