The Oi Hockey Stadium (Japanese: 大äºÂãÂÂãÂÂã±ã¼競æÂÂå ´, à Âi hokkàkyà Âgijà Â) is a Japanese field hockey stadium built on the occasion of the 2020 Summer Olympics in Tokyo. It was inaugurated on August 17, 2019. The stadium is located in the à Âi Futà  Chà «à  Kaihin Park in the Shinagawa district and has a capacity of 15,000 spectators.
During the construction of the playing field, attention was paid to sustainability. The synthetic turf on the site is Poligras Tokyo GT, a product of the Sport Group that also produces AstroTurf. The mat consists of sixty percent sugar cane, and needs two-thirds less water than is usual for wetting hockey fields.
