The Japan Sumo Association is putting its considerable weight behind the 2020 Tokyo Games as it looks to use the international extravaganza to promote the country's national sport.

On Tuesday at the famed Ryogoku Kokugikan in Tokyo, the JSA formally announced plans for Grand Sumo, a special two-day exhibition to be held on Aug. 12-13 between the Olympics and Paralympics.

The two-day tournament, which will replace the jungyō (regional tour) that is traditionally held between July's Nagoya Basho and September's Autumn Basho, will consist of a tournament on each day with the winners to face off at the end of Day 2.
