There is a forum for discuusion of Yahoo Japan. 
It can be found at the Anime Chaos site.

However, we don't want a bunch of "LOOK HERE" 
posts either. ~_~  The final thought on those 
types of posts is listed in the Q&A of my Yahoo 
Japan Information page.

Namely: Trust us! Other people have seen it too! 
Please enjoy looking at it in silence.

Many Sharp Smiles,
