The Ishido school (石堂) traces its root to Omi Province, where smiths surnamed Hioki and bearing names such as Ishido worked before the line dispersed across the country in the early Edo period. From that Omi stem grew four principal branches: the Fukuoka Ishido of Chikuzen, the Edo Ishido carried east by makers who had first gone up from Omi to Kyoto, the Osaka Ishido seeded by smiths who settled in the merchant city, and the Kishu Ishido working under the Kii daimyo.
