Then again, its not local, so maybe thats why they dislike it (maybe I am being somewhat racist/stereotyping, but I have heard that Japanese are very much focussed on their own culture).
Actually, Bitcoin is absolutely local to Japan...the first bullet point on any presentation to Japanese people
always should be that Bitcoin was created by a 36-year old Japanese male
Second bullet point that the first major exchange was HQd in Tokyo.
Third bullet point that Bitcoin Jesus AKA Roger Ver, out of all the countries on this planet, selected Japan as his place of residence.
Just those three should get their nationalistic juices flowing profusely.
PS: and, of course, the Japanese flag is perfectly minimalist and balanced for the addition of a lovely
BTC symbol in the middle of that red circle.
