The Dojo Kun—or training principles—associated with Gichin Funakoshi, the founder of Shotokan and "father of modern karate," serves as the ethical compass for practitioner development. As karate evolved from an Okinawan self-defense art into a Japanese Budo (martial way) in the early 20th century, Funakoshi formalized these five core precepts. Rooted in Bushido and Confucian philosophy, the Dojo Kun governs far more than behavior inside the training hall—it builds strength of character for everyday life.

While Funakoshi’s Niju Kun (Twenty Precepts) offers a broader philosophical framework, the Dojo Kun remains a concise, daily guide for practice.

Simba Dojo proudly carries on this time-honored tradition. We abide by these five core principles to guide every student toward continuous self-improvement. In traditional Shotokan, every precept begins with the word Hitotsu ("First"), signifying that each rule carries equal weight:

• Hitotsu: Seek perfection of character (Hitotsu, Jinkaku kansei ni tsutomeru koto)

• Hitotsu: Be faithful (Hitotsu, Makoto no michi o mamoru koto)

• Hitotsu: Endeavor to excel (Hitotsu, Doryoku no seishin o yashinau koto)

• Hitotsu: Respect others (Hitotsu, Reigi o omonjiru koto)

• Hitotsu: Refrain from violent behavior (Hitotsu, Kekki no yū o imashimeru koto)
