You're too concerned about the toilet.

I feel Japanese people, especially the younger generation, are fixated on Japan and thinking too small. What surprised me was that one reason Japanese youth avoid going abroad is "because the toilets are dirty." To foreigners, that sounds like a joke (laughs). In Korea, because the market has limits, they naturally look to the world. Plus, they're good at imitation. They quickly copy and adopt things popular overseas. Japan, on the other hand, is good at adaptation. They adapt things repeatedly to suit Japanese tastes, often to the point where they don't work outside Japan. So, everyone just stays within Japan, settling in. But for young people, I think what's needed isn't harmony with everyone else, but the boldness to do things others aren't doing.
