 Wrestlers Posture During Ceremony

    Special Japanese sumo wrestling under classical rules was held at the Kokugikan Amphitheater in Tokyo as a newly prepared altar looked down on them from the third floor. After ceremonies in the ring, the leading sumo wrestlers demonstrated various set sumo thrown and holds, those taking part including grand champions Futabayama and Minanogawa. This was followed by regular sumo matches.
