Futsal in Shibuya
There are several good futsal courts in Tokyo. Due to lack of land in the city center the ones with best access are often found on rooftops. One of the more spectacular options is Adidas' court on top of the Tokyu building right at Shibuya station, perfect for a breezy late night summer activity. Since futsal is very popular it is recommended to book well in advance. Rates differ heavily over the day and members get to rent the court an early afternoon hour for 5,250 yen whereas an evening hour sets you back three-fold. Rental gear available.
