Hi JoeS, firstly you have to understand the Japanese culture.. Unlike the European or Americans, Japs are not keen on shouting, talking to strangers, or minding other business..
You can easily look into the lodestone for LS, and then try to send a tell to one of the members, I know it looks like a lot of effort, but it works for me.. approaching them individually helps you (with luck) to get in touch in them..
They are nice people, but rather shy..
