For some curious reason, Basque cheesecakes are popular in Tokyo. Here's one from one of the many fancy baking shops here.

My wife is Basque (French side). Every time I go there I witness endless discussions about "who make the best gateau Basque (biskotx)". It's really an obsession. But the biskotx is made with shortbread and I've never heard of the Basque cheesecake.
I'll ask about it the next time I'm there, but I'm pretty sure this will start a fight.
