Norimitsu Onishi reports in the New York Times that the Japanese government has recognized the indigenous rights of the Ainu people.

The Ainu had lived on Japan’s northernmost island for centuries, calling their home Ainu Mosir. But just as with America’s expansion West, the Japanese pushed north in the late 19th century in the first sign of their imperialist ambitions. Japanese settlers decimated the Ainu population, seized their land and renamed it Hokkaido, or North Sea Road.

And yet it was only a few weeks ago that the Japanese government finally, and unexpectedly, recognized the Ainu as an “indigenous people.” Parliament introduced and quickly passed a resolution stating that the Ainu had a “distinct language, religion and culture,” setting aside the belief, long expressed by conservatives, that Japan is an ethnically homogeneous nation.

The recognition — coming after decades of opposition by a government fearful of compensation claims — seemed timed to an international conference of indigenous peoples that Japan is hosting this week in Hokkaido. The Ainu’s lack of recognition could have proved embarrassing for Japan’s government, particularly since the conference also comes close to the Group of 8 summit meeting in Hokkaido next week.

In a study by the Hokkaido prefectural government in 2006, just under 24,000 people identified themselves as Ainu. Most were of mixed blood and lacked the telltale fair skin or hirsute features that distinguished older Ainu from the Japanese. But it is not known how many live outside Hokkaido since Japan has never conducted a nationwide census of Ainu.

“In Japan’s case, for better or for worse, the assimilation policies since the Meiji era were so successful that almost nothing remains of the Ainu’s traditional way of life,” he said. In 1869, one year after the start of the Meiji era, Tokyo set up the Hokkaido Colonization Board to encourage Japanese settlers to move to Hokkaido. The Ainu were eventually stripped of their land, forced to abandon hunting and fishing for farming, forbidden to speak their own language and taught only Japanese at school. That history — little known by the Japanese today and even among the Ainu themselves — was repeated later in Japan’s Asian colonies.
