Exploring the Mind and Body through Aikido

Mugenjuku is a non-profit organization dedicated to deepening the understanding of the mind and body through Aikido, and pursuing the path of harmony with others.

What is Aikido?

A traditional Japanese martial art that utilizes the mechanisms of the mind and body to control oneself and others.

Aikido does not aim to defeat or injure an opponent. Instead, its purpose is to harmonize your energy (ki) with your opponent’s and guide them.

The ultimate principle of Aikido techniques is to blend your own strength with the pushing or pulling force of your opponent.

Exploring the Mind and Body

In Aikido, we minimize the use of superficial muscles and instead utilize “center power”—strength generated from the body’s core.

At the same time, we cultivate a calm and peaceful mind, always maintaining emotional balance.

Practical Self-Defense

We train following the framework of Yoshinkan Aikido, which has been practiced by the Tokyo Metropolitan Police Department for many years.

It is highly effective as a form of self-defense to protect yourself and your loved ones without causing unnecessary harm to others.

Improving with Age

Aikido is well-known as a lifelong martial art where practitioners continue to improve as they age.

Because it can be practiced equally regardless of age, many parents and children enjoy training together.

Features of Aikido Mugenjuku

Learning Together with People from Diverse Backgrounds

The name “Mugenjuku” comes from the concept of “a place to transcend one’s limits and realize one’s infinite potential.”

At Mugenjuku, people who are dedicated to their studies, work, families, and hobbies gather with the shared goal of further improving themselves.

We value overcoming our self-imposed limits together with our teachers and fellow students. This provides an excellent opportunity to re-evaluate your existing values and habits.

Because training is tailored to each individual’s physical abilities and age, you can progress at your own pace.

Student Testimonials

Highly Rated
by Our Students.

The appeal of Aikido lies in the coolness of its flowing movements. I think it’s so cool how you can effortlessly throw opponents one after another as they come at you!
I think I was able to work so hard at it precisely because my parents never forced me to do it.

A sudden hospitalization sparked my interest in the mind and body, which led me to start Aikido.
Rather than focusing on advancing in rank, my goal is to make Aikido a habit and a part of my daily life to maintain my physical and mental health.

Aikido at Mugenjuku offers the joy of learning logically and stepping up your skills. I feel like there are an infinite number of Aikido techniques, but there is a real fascination in gradually progressing—mastering a simple technique and then moving on to a slightly more difficult one.

I started because I admired the hakama worn by an actress in a TV drama. The training ground for Aikido isn’t just on the tatami mats; it’s in everyday life. Since I started Aikido, I’ve received so many more compliments on my posture from the people around me.

Through Aikido, I learned that to move people and organizations, it is important to accept rather than resist.
You invite a movement, the opponent moves, and you use that movement to ultimately control them with flexibility and grace. What we try to achieve in business and in Aikido is exactly the same.

Frequently Asked Questions

Furthermore, 90% of our new members are complete beginners to martial arts.

Can parents and children participate together?

Yes, parents and children can participate together. We offer a discount for parent-child participation (500 yen off for the adult).

Parents can join the children’s class, or they can participate separately in the adult and children’s classes held on the same day.

How is it different from other martial arts or activities?

In Aikido, the goal is not to hurt others or determine a winner and loser, but rather to harmonize your energy (ki) with your opponent to guide and control them.

Also, since you always practice with a partner rather than alone, you learn how to cooperate—an essential skill for social life.
