Born Haruyoshi Matsumoto(松本治義)in 1940 in Shizuouka prefecture, Matsumoto Shouseki has been making Bonsai pottery, beginning as a hobby, since 1958. He was a new art exhibition co-winner in 1975, and has exhibited several times at the Shohin Kobachi Exhibition.
Initially he made only unglazed pots, but over time he has broadened his repertoire to include many various styles, including glazed pots and carved pots, but now specializes in painted and unpainted pieces made from native Arita porcelain, mostly in akae and sometsuke. In addition to making pots, these days he also spends quite a bit of his time teaching.
