The Ainu language and indigenous language archive project ``Basic research on creating a database of Ainu language research materials'' transcribes research audio materials of Ainu, one of the endangered languages in Japan, and creates various indexes. This is a project to create and make it easier to use from various aspects.

Since the source material was a survey intended to collect conversational expressions actually used in daily life, the database was equipped with a function to search for Ainu words from Japanese. We aim to produce research results that are useful for this purpose.
