Sapporo Children's Puppet Theater Kogumaza, Puppet theatre in Nakajima Park, Sapporo, Japan.

The Sapporo Children's Puppet Theater Kogumaza is a puppet theater in Nakajima Park that presents performances in a dedicated building surrounded by greenery. The venue hosts regular shows throughout the year and welcomes families seeking interactive entertainment.

The theater was established in 1976 and became the first public puppet theater in Japan, setting new standards for children's entertainment. This founding marked a turning point in how puppet theater gained recognition as a cultural institution for young audiences in the country.

The theatre's name comes from koguma, "little bear", and it runs puppet-making and performance classes for beginners alongside its shows. It also invites professional troupes from elsewhere in Japan and from abroad, and supports amateur groups in Sapporo that struggle to find space to build, rehearse and perform.

The theatre is a one-minute walk from Nakajima Koen Station on the Namboku subway line, at Nakajima Park 1-1 in Chuo-ku. It opens from 9:00 to 17:00 and closes on Mondays, or on Tuesday when Monday is a public holiday.

The theatre opened on 24 July 1976 next to the Nakajima Children's Hall, itself described as Japan's first children's hall, at the entrance to Nakajima Park. It was the idea of Sapporo mayor Takeshi Itagaki, who wanted a "dream facility" for the city after visiting a puppet theatre in Sapporo's sister city, Munich.
