May 14

Today is けん玉の日 (Kendama Day).

On this day in 1918, the "Nichigetsu Ball"—the prototype of the modern Kendama—was officially registered as a utility model in Japan.

This traditional pastime, rooted in the Edo period, evolved into its current form during the Taisho era and is now loved all over the world, transcending language barriers. The focus required to land the ball and the pure joy of performing a trick continue to captivate people across all ages and borders.

If you have the chance, please try playing with a Kendama sometime.
