contacting JUA or Japanese riders

I’m planning on going to Tokyo the week before Unicon this summer and I’m really wanting to meet some Japanese riders to show me some local spots to do some riding.

Unfortunatly I have no idea how to get in contact with them. Both the CUA and HK people have easy to find websites with english but the only website I could find for the JUA was the Miyata website, and I’m not sure if they would be able to help me or not.

So any info would be great.
