I'm surprised to see you write in English.
Lol yeah they can.... the reason why you never see their names in Japanese symbols is because you can't put them like that i believe.Can they even access our PSN? Never seen anyone with a Japanese lettered name on.
Not sure if anyone in this thread is still alive/ active, but I'll be heading to Japan, Tokyo area on August 13 for Comic Market and then staying for about a week. Don't know who I'd get in contact with to get some games in on the arcade port of DOA.
