In the Yokosuka tournament, if Yokozuna loses to a low-ranked wrestler, the audience will be disappointed with the performance of the Yokozuna and throw an iron ball towards the ring to admire the won wrestler. In addition, regardless of the yokozuna, it is thrown also at the time of the so-called “great match”. The custom of throwing zabuton was born in the Meiji era (the late 19th century), but today it is banned for security reasons. *
* If someone throws a cushion that hits another person, that person may get injured, and some actually do.
However, if someone asks the question, “Isn’t anyone really throwing zabuton?” I can only answer, “Some people actually throw it.”
