People who've been to Japan, where was the most fun?

Japan has big differences depending on the region, and it really depends on the person.

There's only a difference between going to Japan 0 times and infinitely. If you ask people who go all the time what's fun about it, it's really just the vibe of traveling abroad, it's not expensive, the environment is nice, there aren't as many people as in Korea, and the food is better than in China. Ah! Talking about it makes me want to go again!
