After 1869, the northern Japanese island was known as Hokkaido;[2] and regional administrative subdivisions were identified, including Shiribeshi Province.[1]
In 1882, the Hokkaido region was separated into three prefectures — Hakodate Prefecture (函館県), Sapporo Prefecture (札幌県), and Nemuro Prefecture (根室県). In 1886, the three prefectures were abolished, and Hokkaido was put under the Hokkaido Agency (北海道庁).[3] At the same time, the Shiribeshi Province continued to exist for some purposes. For example, Shiribeshi is explicitly recognized in treaties in 1894 (a) between Japan and the United States and (b) between Japan and the United Kingdom.[4]
659—the area named "Shiribeshi" first appears in Japanese historical records. The Nihon Shoki records that Abe no Hirafu (fl. 7th century) was dispatched by the imperial government in Kyoto to subdue the aboriginal inhabitants of the area, referred to as emishi.[5]
