Karate in Japan
The sport has declined in popularity and is more popular abroad. Karate at the 2020 Summer Olympics is going to be a debut event at the Summer Olympics.
Breaking (martial arts)
For hundreds of years, Korean has had a power circus (power magic show, power performance art) called Charyuk/Kihapsul which is pronounced Kiai-jutsu in Japanese for reading the same 3 Chinese letters in a different dialect. This predates Karate Breaking. Breaking Game already existed before Karate in the category of power circus performance art, not a part of striking martial art but correlating with wrestling, circus, Qigong (also called Kooksundo, Seonsul). Mas Oyama (Choi) introduced Breaking/Tameshiwari into the modern Karate culture. Karate also testified that Breaking/Tameshiwari is a form of personal trial like mountain climbing. "It isn't Karate, Kung Fu or Tae Kwon Do, but it is the same kind of personal trial that is Tameshiwari."
