It was 10:30 on a cloudy weekday morning in May, and 40-year-old Masakazu Meguro and his coworkers who make up Calcio Atleta las Manos were happily spending the morning of their precious day off to playing "futsal."

Sounds like just another one of the hundreds of enthusiastic five-member soccer teams out there? Perhaps, except that they were playing smack in the center of the teeming area near JR Shibuya Station. In fact, they were very close to the statue of the dog just outside the Hachiko Exit -- only vertically.

Just 40 meters above ground, there is an atmosphere completely different from the hectic world of street-level Tokyo.
