 As his teacher did, Shunkō used a jar-shaped seal and was known as ("little jar").At 45, the right-handed Shunkō became partially paralyzed and ceased designing prints, although he continued producing paintings with his left hand.Shunkō lived in Nihonbashi Hasegawachō in Edo (modern Tokyo) and was a student of Katsukawa Shunshō—possibly the master's first.
