Warhammer 40k players in Osaka

I live in Osaka and I have been playing only with a mate of mine at the GW Store and yesterday I tried for the first time the Y&Y shop which is nice.

There were a lot of people but it isn't easy to connect with Japanese people at the very first time and ask them to play a game (I do speak japanese well)

So I was wondering if there are other 40k players who shares the hobby and play the game in Osaka area,it would be nice to connect with new people and roll some dice.
