Kotō ware (湖東焼, Kotō-yaki) is a type of Japanese porcelain traditionally made in Hikone, Shiga in the former Ōmi Province.
The Ii lords of Hikone Domain became the patrons and continued this tradition until the Meiji restoration in the years Tenpō 13 ~ Bunkyū 2 (1842 ~ 1862).

Lord Ii Naosuke was assassinated during the Sakuradamon Incident (1860), the downfall of the family began, and the patronage of the production of kotō ware was gradually lost, ceasing in 1895.
