noun
one-legged hopping sumo; heron sumo
A traditional Japanese children's game where two players hop on one foot and try to push each other out of a ring or make the other put their other foot down. The name evokes the image of herons (鷺) standing on one leg.
運動会で鷺相撲をして遊んだ。

鷺相撲は片足で跳びながら相手を押し合う遊びです。
Heron sumo is a game where you hop on one foot and push each other.
Another name for the same game, more directly describing the hopping motion (けんけん). 鷺相撲 uses a more poetic, heron-related image.
Compound of 鷺 (sagi, 'heron') and 相撲 (sumō, 'sumo wrestling'). The name comes from the way players hop on one leg, resembling a heron standing on one foot.
