I do not think so. I suppose there are many more concerts in U.S. than in Japan. However, not many people seem to post about the event that they know of to the Event section of this site. Currently, most records seem to be that of Japan (which does not show in English site.)

Please do post about the events, recitals, and concerts to the event section of Marimba.org! It is not necessary at all to be YOUR recital. If you get to know that an event is coming on the way, then please do post!
