Two books on Ainu language studies: 1. Ainu Place Names Explained, Author: Genzo Sarashina, Miyamashobo, First edition, July 30, 1982 2. Ainu Language Collection: A Small Ainu Dictionary Both books were purchased and placed on the bookshelf, where they have remained for several decades. They have discolored with age, but there are no signs of the pages being thoroughly opened. I believe these books would be very useful as research materials or practical books for hobbyists. Price negotiations are not accepted; I will consider price adjustments as needed.
