Thinking of visiting an exhibit in the Met Museum this month. It's part of the Japan-Philippines friendship month festivities.

There's also a film festival,

I've been an avid Otaku for years now, but I've been brewing a fascination with other things Japanese. Of course the food would always be there. Hahahaha.

But seriously sure, I've enjoyed anime, manga, shooting cosplay, etc... but this is just the small tip of the iceberg in relation their history and culture. The historical and cultural aspects should be worth the additional learning.
I should visit Tokyo again.
