Makes sense. Density follows internet usage/density. The strange exception is Japan and the rest of eastern Asia. Those countries generally have above average internet usage/access but Bitcoin popularity lags.
It's my impression Japan and many other Asian countries practically have their own internet, for all that the users in the west and the east connect. Strong language barriers, for one.
Speaking for Korea they have their own domestic web portals that have a huge percent of the market/usage share hear. Naver and Daum being the equivalent of say Google and Yahoo or something. Lots of that due to language, but I expect a large part is also due to the protectionist/nationalistic mindset and economic situation here. Koreans just like using Korean stuff. Couple that with the large chaebol (massive multinational, super vertically integrated conglomerates, think Samsung, Hyundai, LG) having such a stranglehold on the country, and there isn't a lot of room for different things.
