Shigaraki Kotōkan, Ceramics museum in Kōka, Japan.

Shigaraki Kotōkan was a private ceramics museum in Chokushi, Shigaraki-chō, Kōka, Shiga Prefecture, next to the Shiga Prefectural Ceramic Forest. It opened in 1991 with two exhibition rooms, one for medieval Shigaraki ware and one for early modern pieces, centred on old Shigaraki ceramics donated by the Shigaraki Old Pottery Lovers' Association. It closed in 2013 when its operator, Marukatsu Pottery, went bankrupt.

Founded in 1991, the museum documents ancient firing techniques from Shigaraki, one of Japan's six oldest kiln centers. Pottery production in this region extends back several centuries.

The museum displays Shigaraki ware marked by rough surfaces and natural ash glazes from wood-fired kilns, which define the room's visual character. These pieces reflect how potters here have worked with local clay for generations.

The museum closed in 2013 after its operator, Marukatsu Seitosho, went bankrupt, so there are no exhibitions or workshops to visit. The building stood unused until Koka City bought the site in 2019; Shiga Prefecture then took over the land and moved the Shigaraki Ceramic Technology Center there.
