ring-entering ceremony (in sumo)
The ceremonial entrance that top-division sumo wrestlers perform before a day's bouts, in which they step up onto the ring in their decorative aprons. The yokozuna (grand champion) performs a special solo version with attendants.
Compound of 土俵 (sumo ring) + 入り (entering). A sumo term for the ceremonial procession onto the ring.
Cultural note
There are two main types: the group 土俵入り of the top divisions, where wrestlers line up in ornate aprons (化粧まわし), and the solo 横綱土俵入り, where the grand champion performs a stylized routine with two attendants.
