is a type of Japanese pottery that was made by the Buddhist nun Ōtagaki Rengetsu (1791–1875).
She was a prolific poet and calligrapher, but also an artisan. She created a number of vessels for sencha and chanoyu tea drinking traditions.[1] She also created a large number of sake vessels such as tokuri flasks and guinomi cups.[2] She adorned her ceramics with poems written in her calligraphic style.
Her style of ware was continued even after her death and a traditional center of production was in Okazaki, Kyoto.
