A stone monument stands on Kameyama Street, near the Kameyama-shanaka Memorial Hall in Nagasaki, at the site of Kameyama-shashinaka. In the 4th year of culture (1807), the Kameyama ware kiln was opened with the main focus of Jingohei Ogami. It had mainly baked water bottles ordered by the Netherlands, but due to the decrease in the arrival of Dutch ships, it began to produce white-porcelain dyeing, and eventually closed kilns in the first year of the Gyeongsang (1865). It is said that Ryoma patronized a teacup of Kameyama ware with the same dragon drawn as his first name, and established Kameyama Shahong on this kiln site. At present, parts of the kiln remains have been confirmed, with information boards on the side of the stone monument, and an exhibition shelf on the outer wall at the Irabinhei community hall in Soba to display works by Kameyama ware.
