Japanese versions of the 2018 Official Wheelchair Basketball Rules, the 2019 Comments and Interpretations of the 2018 Official Wheelchair Basketball Rules, and the 3×3 Official Wheelchair Basketball Rules have been published and can now be downloaded here.

All documents are currently valid and are mandatory for all official IWBF competitions.

"I would like to thank Eisuke Kanno, an international referee instructor and former international referee, as well as everyone who assisted him including the Japanese Wheelchair Basketball Federation, for the excellent job they have done in translating these documents for IWBF," Cristian Roja, chairman of the IWBF Technical Commission, said.

"This is another huge contribution of an international technical official’s free time to help ensure there is a better understanding of our game all over the world."

He added: "We understand that the rules are not the most attractive or spectacular part of the game, but to be able to produce them in different languages, as we are doing, is vital to open the door to new spectators, players, coaches and officials to join wheelchair basketball.

"With the Tokyo 2020 Paralympic Games on the horizon and wheelchair basketball being in the spotlight and attracting new audiences in Japan, the Japanese versions were a priority."

Wheelchair basketball at Tokyo 2020 will be held at two venues, with Musashino Forest Sport Plaza hosting group-stage matches and Ariake Arena staging finals.

There will be 12 men's teams and 10 women's teams competing.

Competition is due to run from August 26 to September 6.
