I think not. Mr. T died, I think. Some of the trees went to another bonsai museum in Tokyo.
Bill V discussed it (here?) recently. The building, he said, is now a "noodle house." Glad I was able to visit when I did. They acted if no westerners had ever visited . . . I got a personal tour and was given several magazines to take home.
I'm not aware of a bonsai museum in Tokyo, but there is a new one in Omiya. Quite a nice facility with some famous trees in the courtyard too. Seems to be aimed at the general public. I think admission was 500 yen.
Thank's a lot for all the suggestions. I went to Omiya bonsai village today and visited the museum as well as the 5 nurseries there. Unfortunately none of them allowed photography but I was amazed by the quality of bonsai there. Especially at Mansei-en owned by Mr Kato where I met Juan, a californian who has been studying Bonsai in Japan for a year. I was able to see "the oldest bonsai in Japan" along with the current Kokufu winner (hormbeam) and last year's kokufu winner (pomegranate).
