He doesn't have his own shop but sells his jewelries on the temporary booths in the famous department stores in and around Tokyo. This week he is coming to a big department store in Yokohama to display & sell his new works. I visited him there but not to buy one of them but ask him to make another earrings for me alone :)
We talked about it for a while and he drew rough design on his sketchbook. It's a great fun to wear the jewelries I myself ordered and this process (talking, making a design...) makes me feel like I make them with the craftsman.
His jewelries are not cheap but not too expensive, I sometimes permit myself this small luxuries.
