What is Ryushinjuku?

“Ryu” signifies flow, “Shin” represents the heart, and “Juku” refers to a place of learning.

Together, the name expresses a place that nurtures a flexible heart—like the flow of water—capable of adapting to any situation and, at times, breaking through obstacles.

Ryushinjuku is a dojo that offers instruction in traditional Japanese martial arts, specifically Aikido and Iaido (Japanese swordsmanship).

Through the practice of these arts, Ryushinjuku seeks to cultivate both mental and physical strength and flexibility, helping practitioners develop the resilience needed to face challenges in everyday life.

Who We Are

Ryushinjuku was established to carry forward the legacy of the dojo formerly known as City Aikido and Swordsmanship of Los Angeles.

We are affiliated with Aikikai (合気会), the original organization of Aikido in Japan founded by the master of budo, Morihei Ueshiba O-sensei. We are also a member dojo of the United States Aikido Federation (USAF), the largest Aikido organization in the United States.

The USAF was founded by Yoshimitsu Yamada Shihan, one of O-sensei’s direct students and a legendary figure in the Aikido world.
