I lived in Japan for a long time and still visit frequently. I think the answer depends in part on how old you are, your ethnicity/nationality, your financial situation, your work situation, etc. I agree with LapLap that's it love/hate thing. For me it was a love hate cycle. First I loved it, then I hated it, then I loved it. Over time the cycles got longer. Initially, it was week to week, then months, then years, and now decades.
