TOKYO (REUTERS) - Thousands gathered to attend an outdoor sumo wrestling tournament in Tokyo.

Sumo, Japan's national sport, has roots in religious rituals at Shinto shrines to pray for abundant harvests.

The wrestlers weigh about 120kg each and grapple, slap and push each other for victory while wearing traditional loincloths.

The Spring Festival was held at the controversial Yasukuni Shrine.
