Bu Tactical makes modern martial and survival applications optimized through traditional martial wisdom. The word “Bu” in Japanese loosely means “martial” or “war.” It more accurately is translated as stopping or ending, as in the capability to stop or end hostility towards one’s self. In fact, in 1882, Okinawan karate master Sokon Matsumura penned seven virtues of Bu:

1. Bu prohibits violence
2. Bu keeps discipline in soldiers
3. Bu keeps control among the population
4. Bu spreads virtue
5. Bu gives a peaceful heart
6. Bu helps keep peace between people
7. Bu makes people or a nation prosperous

Budo, or bujutsu, in turn, is the study of discipline and control, preventing violence against one’s self through superior mastery and giving no cause to make others direct hostility towards you. The notion has been mirrored throughout time and nation, such as the Latin “Si vis pacem, para bellum” (If you want peace, prepare for war), Sun Tzu’s quote “The supreme art of war is to subdue the enemy without fighting,” and lastly, “Only the warrior chooses pacifism; all others are condemned to it.”

Through modern protection practice (tactical) and traditional martial study, the Bu Tactical line of products and training seek to prepare the law abiding citizen and modern personal protection professional with optimal applications providing strength and proficiency, so that peace and well being are preserved.
