Chirpoy appears on an official map showing the territories of Matsumae Domain, a feudal domain of Edo period Japan dated 1644, and these holdings were officially confirmed by the Tokugawa shogunate in 1715. Administration of the islands came under the Matsumae domain's regional office location on Kunashir from 1756. In 1801, the Japanese government officially claimed control of the islands, incorporating them into Ezo Province (now Hokkaidō), but sovereignty passed to the Empire of Russia under the terms of the Treaty of Shimoda in 1855. Under the Treaty of Saint Petersburg (1875), sovereignty passed to the Empire of Japan along with the rest of the Kuril islands. The islands were formerly administered as part of Uruppu District of Nemuro Subprefecture of Hokkaidō.
