Sumo wrestlers made from cardboard will compete on the dohyo ring at the Hikifune Culture Center in Sumida Ward, Tokyo, on Dec. 21.

The organizing committee is actively welcoming participants for sumo wrestler-making workshops ahead of the tournament at four locations in the ward.

The “Dondoko! Giant Paper Sumo Wrestling” started in 2019, and this is its seventh year. Each year, many parents and children participate in making the 1.8-meter-tall paper sumo wrestlers, resulting in creative designs featuring motifs of animals and fictional characters.

A total of 32 completed paper sumo wrestlers will compete in a tournament with participants pounding a wooden dohyo to advance the bout. The event website will feature a pre-released “wrestler directory,” along with popularity polls and predictions for the winning wrestler. The tournament will be live streamed on YouTube.

Sumo wrestler-making workshops will be held on Nov. 29 and 30, and Dec. 6 and 7, with two workshops per day. Applications are accepted in groups of 3-8 people, with a deadline 10 days before each workshop date. If applications exceed capacity, participants will be selected by lottery.
