Overview: From Shibuya's newest skyscraper to nearby Shinjuku, where a man in a tiger mask cycles the city streets. Why did he choose such a life? After he introduces us to Shinjuku's lively back alleys, we ride west into a surprisingly natural landscape. By a tranquil river, we meet an artisan reviving a 200-year old dyeing craft, and in a mountain forest a far-sighted woodsman explains his ecological approach. City and society change with the times, but these are people holding fast to their chosen paths in life.
