I often look ridiculous in Japan. There's really no way to eat in Japan, particularly kaiseki in a traditional ryokan, without offending the Japanese horribly. Every gesture, every movement is just so atrociously wrong, and the more I try, the more hilarious it is.
Tokyo would probably be the foreign city if I had to eat one city's food for the rest of my life, every day. It would have to be Tokyo, and I think the majority of chefs you ask that question would answer the same way.
Of course, when it comes to Japanese role-playing games, in any role-playing game in Japan you're supposed to collect a huge number of items, and magic, and you've got to actually combine different items together to make something really different.
There are some ghost stories in Japan where - when you are sitting in the bathroom in the traditional style of the Japanese toilet - a hand is actually starting to grab you from beneath. It's a very scary story.
