Tokyo

I couldn't have said it better.

I didn't spend much time in Tokyo, I just breezed through while traveling north.

Encapsulated.  The hard part was surviving the freezing process, but after that I was preserved quite well.  Waking up in a room of laughing aliens was a bit weird, though.

I stayed in Shinjuku, which was slightly less insane than I remember (thankfully).  I stumbled upon this maze of alleys filled with bars that only fit five people each.  This kind of thing completely freezes me with indecision - walking into any of these bars feels like you're crashing someone's party.
