Machiya-Bito is a gallery in Tokyo, in the Machiya neighborhood, in Shinagawa district. This district is famous for its craft workers and they also do have the only tramway of Tokyo. The neighborhood is authentically and a great place to discover Japanese culture with historical roots. We where warmly welcomed by Meiko Kochiya-san. She is a great personality with a huge network of artists and crafts folks of Shinagawa. You should definitively check out her planning to see if you could pop by when in Tokyo. Meiko-san speaks french (she is sometimes assisted by her English speaking daughter).
If you want to contact them, say hello from Aina and Karianne =)
Highly, highly recommended!!
