HELLO there joganse san !! From the roof of Japan...WELCOME to JREF !! Please do spend some time with us, and enjoy your stay here. One good way to get to know folks here on the forum is to join in and share your thoughts, and learn with all of us. As time goes on, I'm sure you'll find some friends here.
Not all of the members are Japanese nationals, and, in fact, few are. This, however, should be no barrier to joining in and being a regular poster here. I look forward to talking with you later !! (and it might be good to introduce yourself a little more, telling us about things Japanese that interest you. MM
ps-I moved this here since you were not looking for some particular person, but just want to meet some who are Japanese nationals.
