Understanding “Osu” in Karate — A Personal Perspective

In this episode of Karate Bites, Mike Williams Kyoshi takes a deep dive into one of the most commonly heard — and often misunderstood — words in the world of karate: “Osu” (押忍).

More than a simple dojo greeting, osu carries layered cultural meaning, controversial origins, and varied use across different karate styles.

Mike shares his personal journey — from early training where osu was used everywhere, to a pivotal moment in 2003 during a private meeting with Mabuni Kenzo Soke, son of Shito-Ryu founder Mabuni Kenwa. That conversation forever changed how he views — and teaches — the word osu.

In this reflective episode:

• What does osu really mean?
• Why is it embraced in some karate styles, and avoided in others?
• Is it a sign of respect — or a misunderstood term with deeper implications?

Join us as we explore the cultural, historical, and personal significance of osu — and why understanding the words we use matters in traditional karate-do.
