Koichiro Osaka, the founder of an eclectic art project space in Asakusa, and I meet at a cafe in Tokyo's Shinagawa Station. From where we are sitting we have a bird's-eye view of a briskly moving, and interminable stream of dark-suited salarymen and women rushing to catch their trains after work.

"It's amazing, isn't it?" I ask.

"I'm not sure if it's good or not, though," replies Osaka, drily.
