For a good overview of tech events going on in Japan, see https://www.google.com/calendar/embed?src=fvijvohm91uifvd9hr...

One thing you could do is try to support some local events. Some ideas:

* Give a presentation at a local event (English is fine; I can introduce you to event organizers in the design / Ruby community) * Serve as a mentor for a startup weekend - http://startupweekend.jp/ * Participate in this event for event organizers: http://devlove-kansai.doorkeeper.jp/events/2338 (I'll be presenting in [broken] Japanese)

Feel free to follow up with me if you have any more specific questions.
