Tokyo is the president of the long-established bookstore "Yukyudo Bookstore" in the old bookstore district of Kanda Jimbocho.

Yukyudo Bookstore, which was founded in 4 and celebrated its 2015th anniversary in 100, is known for handling many old books on mountains, nature, animals and plants.

Including the back number of mountaineering magazines, there are books and magazines that are now discontinued, first edition books and books with the author's signature, and there are many inquiries from people looking for the book they are looking for, so I am interested in mountaineering books. It is considered one of the sacred places for climbers.
