Hi Darren. I don't live in Tokyo. However the best person to contact is Juergen Wittstock.

Good luck and enjoy your visit to Tokyo

Welcome to the site!
Thank you for joining this website, and I hope to see you at a training-run or a race soon. We try our best to assist foreign runners to navigate to difficulties of the Japanese running bureaucracy, and fortunately, have a lot of Japanese members who can help with that.
I'm looking forward to seeing your blog-posts and other running-related content on this website!
And a little hint: Pop out the chat-box when you are on the site, then it is much easier to see when somebody is talking to you.
Cheers, Juergen (website-creator)

P.S.: Thanks for the unusual pic, is that some kind of triathlon?

Hehe, well, I was sort of joking, but there are all kinds of Triathlons now... CU in Tokyo!
