Interesting on this member's info. It shows the same IP for a old member "Tears For Fears" who was active 2003 to 2009 and was into gaming. His location was untraceable back then. Nissin is a Japanese noodle company which is an interesting logo for a person living in Sweden. Zukura's location is also untraceable.
There's noting odd about that considering that this is a site regarding Japan. Now, if it depicted a jar of vegemite, it would be very suspicious indeed.
More than fifteen years ago, many were trying to get Japanese email addresses for all kinds of reasons: to sign up to Japanese websites (anyone remembers Mixi?), to download Japanese games, to access dating sites, and for other less legitimate purposes. And in the heyday of Jpop and anime, it was simply "cool" to boast a ".jp" address.
