Matsumae clan
The Ainu people inhabited the Kuril Islands from early times, although few records predate the 17th century. The Japanese administration first took nominal control of the islands during the Edo period (1603-1868) in the form of claims by the Matsumae clan. It is claimed that the Japanese knew of the northern islands 370 years ago. The "Shōhō Era Map of Japan" (), a map of Japan made by the Tokugawa shogunate in 1644, shows 39 large and small islands northeast of Hokkaido's Shiretoko Peninsula and Cape Nosappu. A Dutch expedition under Maarten Gerritsz Vries explored the islands in 1643. Russian popular legend has Fedot Alekseyevich Popov sailing into the area .
