From 6/13 to 15 there is a Hiraga Teruyuki kokeshi exhibition, he is from Sakunami and did the kokeshi that is on the cover of my book!
The address is:
2-4-10 Negishi, Taito-ku, Tokyo
It is REALLY hard to get genuine kokeshi in Tokyo so it is a great opportunity to pick up some of these one-of-a-kind beauties.
