In what year did Funakoshi demonstrate for Prince Hirohito at Shuri Castle?

In 1921, Gichin Funakoshi had the significant opportunity to demonstrate karate for Prince Hirohito at Shuri Castle in Okinawa. This event marked a pivotal moment in the history of karate, as it helped to showcase martial arts to a royal figure and contributed to the growing interest and subsequent acceptance of karate in Japan. The demonstration served as a bridge to formalize karate as a legitimate martial art and expand its recognition beyond the Okinawan islands.

This year is notable not only because of the demonstration itself but also due to the cultural impact it had on the perception of karate within Japan. Funakoshi's role in the demonstration further solidified his position as a key figure in promoting karate, transforming it from a regional practice into a national sport. The choices representing the other years do not hold the same historical relevance regarding this particular event and its influence on karate's development.
