On January 8, we received two karate weapons cherished by our founder, Shihan Isamu Kato (1941–2023), from his family: a pair of nicho‑gama and a nunchaku. These are custom‑made, combat‑ready pieces from the 1960s. Because of their significant historical value, we have posted a detailed report on our international page.

Ms. Nayuru Sakuta passed the examination for 3rd Dan.
In addition, she successfully passed the required kata and kumibo (paired applications of weapon kata) for tonfa and kama, and was also awarded 3rd Dan in Ryukyu Kobudo.
She has been promoted to Shihan-dai (Assistant Instructor).
She is the first female Shihan-dai to master kata and their applications
(kumibo) in all six weapons:
bo, sai, nunchaku, nunti, tonfa, and kama.
