The cost increase is reportedly due to several key factors, including a rise in construction prices across Japan and a focus on making the venue more earthquake-resistant.
The venue developer is Shimizu Corporation, which also constructed Izu Velodrome -- the track cycling venue for Tokyo 2020. The 12,000-seat spectator gymnastics facility is projected to be completed by October 2019.
This venue, located in the Tokyo Bay Area, will reportedly stage boccia during the Paralympics and then will become a convention and exhibition center after the Games.
