I would like to join chans in Japan but I'm fed up with the fact that I can't use it on 5ch, 2ch.sc and 2channel because I don't live in Japan.

Maybe get a VPN or Proxy and use a Japan IP.

Simply move to Japan, how did you not think of this?

I've been in Japan and never thought to post on their textboards. I would stick out like a sore thumb with my horrible Japanese. YANKEE GET OUT!
