Last month we were lucky enough to go to Japan for a week or so. Absolutely amazing place and somewhere I need to spend more time. We based ourselves in Tokyo and and had a day in Kyoto.
Central Tokyo like most cities is full of shops and offices, but the sheer amount of different shops they manage to pack into one building through vertical integration does give that feeling of claustrophobia. We were staying just outside the centre in the Hilton , which is more in the business district of Shinjuku which gave us some relaxation away from the neon and bustle.
