Answer 1

Not sure about Yahoo in particular, but you can try the classified ads in:

http://www.kfm.to/
http://metropolis.co.jp/
http://www.timeout.com/travel/tokyo

Or check this site for a list:

Or try this "friends" network:

As we say here, "がんばってください。”

Answer 2

I would suggest creating a room in the Yahoo! Instant Messenger Chat Area, entitled "Free English Conversation" or "Teach me Japanese, please" You know, something to that affect. I have done that before, and A lot of people will join just to practice their English. Usually there are also a few Japanese members. Consider the time though. The best time to attract Japanese would be around midnight Japanese time, so that would be about 11am in the EST in the USA.

I know several women that have met and married through the internet so they are not beyond starting a relationship via the internet.

Good luck to you.
