I've said it before, and I'll say it again -- the Japanese are weird. I love a lot about the Japanese and Japanese society, but at the end of the day they're weird.
This article from Mainchi Daily News covers the strange world of Japanese ice cream where raw horse meat, whale, and natto (a nasty fermented soy bean product) wind up in ice cream. Now, I like my horse meat as much as the next guy, but I don't want it in my ice cream. Ever.
Thanks to Boing Boing for the tip.
