The IP range is quoted as belonging to and asvertised by trend in USA but looking further you seem to be correct. My observation was made on the fact that it's a US company and the 150/70 range is given by iana as being split into several "districts" including ARIN.

Whether or not it's being "hosted" in Japan, it's operated, I think, from USA.
