However it can't be helped. Many of Japanese don't know where is Scotland. Capercaillie and Runrig were promorted once in the middle of 90's and the CDs were on sale in Japan. Capercaillie performed in Tokyo 1994. But it is difficult to find out the CDs.
Irish music is popular and well promorted in Japan.
There is St Andrew Society in Japan. But the office changes every year. By the way, Japan Scotland Society is a society of Japanese people who love Scotland. I hear there are Scottish country dance clubs in Tokyo, Yokohama, Morioka and Sendai. Tokyo Blue Bell is the most famouse Scottish dance group in Japan.
