The Renshinkan is a Jiyushinkai dojo in Mesa, Arizona. We study various traditional Japanese Budo [martial ways] using the modern educational methods given to us by our teachers. As is the tradition in classical martial arts schools, we are not a commercial business, but rather a dedicated group of students striving to learn what has been passed down from our teachers over the years.


The word renshin holds particular significance to us, not only as a reminder of where we come from, but also of what we are working toward.  The name Renshinkan comprises the following characters:

renRen is a metallurgical term that refers to polishing and forging. As repeatedly pounding heated iron refines and tempers it, so is the student refined and tempered through repeated training. Ultimately, the student will become their own anvil, hammer, and fire.

shinShin means heart or spirit. Shin is also significant in that it is a character that is also used in the name of our family, Jiyushinkai. This character was specifically chosen to show our lineage and connection to our family.

kanKan means hall or building. It is a commonly-used suffix in Japanese dojo names.

We do not take part in tournaments or competitions of any sort. Nor are we a commercial dojo in the normal sense; we are a family. As such, we tend to have rather strict guidelines for entrance.

Our dojo follows Kano’s maxims seiryoku zen’yo [best use of energy] and jita kyoei [mutual welfare]. If a technique will not work when done by a small person against a large person without resorting to speed, pain, or excessive physical force, the technique is either invalid or is being done improperly.

Prospective students are required to watch four full classes and pass interviews with senior dojo members before being allowed to request to join the dojo. This is done so that you can get to know us and we can get to know you. Instructors reserve the right to waive this requirement if a senior dojo member personally vouches for you.

All students in good standing from other Jiyushinkai dojo are welcome to train with us. We have no “mat fee.” We just ask that you let us know in advance when you are coming, how long you will be here, and who your teacher is if we haven’t met you yet.

Please note that we do not offer classes for children at this time. The youngest we will generally consider accepting is age 13.

If you have a serious interest in engaging in sincere spirit forging in a joyous environment, feel free to contact us.


Jiyushinkai is an independent group with roots in the teaching methods of Kano Jigoro, Mifune Kyuzo, Ueshiba Morihei, Tomiki Kenji, Ohba Hideo, Nishioka Tsuneo, and Miyake Tsunako sensei. The senior students of the Jiyushinkai are motivated to teach the less experienced how to “stand on their teachers’ shoulders” as the saying goes. We all have much to learn from each other.
