If you're ever in Japan on March 15....

This looks like it would be a very fun time! Possibly more so if you're single. Free sake by the barrel, free mochi rice cakes! Of course, you might get trampled by elderly Japanese men. And the most wonderful souvineers to bring back to your friends and parents!

I'd definitely have to rate this one as NSFW unless you have a very liberal work environment.
