Tatsumi Ryu, along with Kage Ryu (founded by Aisu Ikosai), Kashima Shinto Ryu (founded by Tsukahara Bokuden), Katori Shinto Ryu (founded by Iizasa Choisai), and Nen ryu ( founded by Nen Yamato Jion), is one of the oldest of the surviving sogo bujutsu (comprehensive system of combat). |
| The Marine Corps Martial Arts Bayonet System |
| This is the enduring credo of the United States Marine Corps. Whether it has become more ideal than reality in recent years is not as important as the concept behind it: Every Marine is a combat Marine; every Marine is trained for combat. |
| AISU KAGE RYU |
| Aisu Kage Ryu is the foundation for some of Japan's most influential koryu, Shinkage, and Yagyu Shinkage Ryu. Interestingly, Aisu Kage Ryu even had an impact on the Chinese. |
