and cultural community. Since late 2011, the Ainu have cultural exchange and cultural cooperation with the Sámi people of northern Europe. Both the Sámi and the Ainu participate in the organization for Arctic indigenous peoples and the Sámi research office in Lapland (Finland). Currently, there are several Ainu museums and cultural parks. The most famous are: National Ainu Museum Kawamura Kaneto Ainu museum Ainu Kotan Ainu folklore museum Hokkaido Museum of Northern Peoples Ethnic rights Legal action On 27 March 1997, the Sapporo District Court decided a landmark case that, for the first time in Japanese history, recognized the right of the Ainu people to enjoy their distinct culture and traditions. The case arose because of a 1978 government plan to build two dams in the Saru River watershed in southern Hokkaidō. The dams were part of a series of development projects under the Second National Development Plan that were intended to industrialize the north of Japan. The planned location for one of the dams was across the valley floor close to Nibutani village, the home of a large community of Ainu people and an important center of Ainu culture and history. In the early 1980s when the government commenced construction on the dam, two Ainu landowners refused to agree to the expropriation of their land. These landowners were Kaizawa Tadashi and Kayano Shigeru—well-known and important leaders in the Ainu community. After Kaizawa and Kayano declined to sell their land, the Hokkaidō Development Bureau applied for and was subsequently granted a Project Authorization, which required the men to vacate their land. When their appeal of the Authorization was denied, Kayano and Kaizawa's son Koichii (Kaizawa died in 1992), filed suit against the Hokkaidō Development Bureau. The final decision denied the relief sought by the plaintiffs for pragmatic reasons, the dam was already standing, but the decision was nonetheless heralded as a landmark victory for the Ainu people. In short, nearly all of the plaintiffs' claims were recognized. Moreover, the decision marked the first time Japanese case law acknowledged the Ainu as an indigenous people and contemplated the responsibility of the Japanese nation to the indigenous people within its borders. The decision included broad fact-finding that underscored the long history of the oppression of the Ainu people by Japan's majority, referred to as Wa-Jin in the case and discussions about the case. The decision was issued on March 27, 1997, and
