The Appeal of Ryushinjuku

It’s next to the supermarket, so it’s convenient to be able to pick up and drop off and shop together

The dojo is located next to the Fresh Plaza Union Tsukazan store.
There is also a Drug Eleven across the road. There are also many stores nearby.
It is a very convenient location for shopping while you are picking up or dropping off your children!

Even the hot summer months are no big deal! air-conditioned

We are equipped with a large air conditioner to prevent heat stroke and maintain focus and quality practice.

Sports insurance is provided in case of emergency

We are committed to providing a safe and enjoyable training environment so you will never be injured.
I am a member of the Public Interest Incorporated Foundation Sports Insurance Association as a precaution, and I have not had a serious injury in the 10 years I have been at the dojo.

All members of the dojo are required to join the Sports Insurance Program of the Japan Sports Safety Association.

Practice up to 5 days a week depending on your motivation

We have a variety of classes to suit each grade level, belt color and lifestyle.
Students can practice up to 5 days a week depending on their motivation, ability and lifestyle.

The little ones imitate their older predecessors, so by far the fastest growing ones!

At the karate dojo, students of various ages get together to practice. The older children take care of the younger ones and learn to pay attention to them and develop their leadership skills.
Younger children look at the older children and imitate them, saying, “I’m a cool guy,” and “I want to be like that.

It’s a rare opportunity in life to have a toss-up.
At Ryushinjuku, all the members, both adults and children, who win prizes in the competition, have a toss-up ceremony with the help of their parents.
Now, let’s work hard and fly!

I’m a member of Ryushinjuku, even though I graduated.

Some students leave the dojo for higher education, employment, or to move out of the prefecture. However, the people you spent time with at Ryushinjuku will remain with you after graduation. You are always welcome to come back to Ryushinjuku. I’ll be waiting for you.

A spacious and clean dojo.

Ryushin Juku is one of the largest dojos in the prefecture, with a floor area of 36 square meters. Since it is a dedicated karate dojo, we have mits, sandbags, and mats on the floor for safety reasons.
We also have changing rooms and toilets with showers. The dojo is cleaned every day so that you can use it comfortably.

Be kind to parents raising their children.

Indoor Baby Space

In the dojo, there are separate areas for practice and observation, so mothers can keep their hands free and babies can move to relieve stress!

Rooftop lawn area

There is a large grass zone on the 4th floor rooftop. Please use it as a playground for siblings during rehearsal time (there are a few rules and regulations to follow, so please ask in advance.

Sometimes you have to change things up.

refresher training

We have a refreshing training session on the roof of the building, and we also have a variety of other games such as dodgeball and chambara to deepen our concentration and interaction.

BBQ for everyone.

Several times a year we have a general club, boys’ club, morning class, and even parents get together for BBQs and year-end parties. It helps to strengthen the team dynamics of Ryushinjuku!

A full range of facilities

Training facilities opened to the general section (adults)

The dojo is open to members of the general public from 10:00 a.m. to 5:00 p.m. daily for self training. The dojo is fully equipped for training.


We will teach you how to take care of your body as well. We also have massage machines available for the general club members to use.

Lots of events. Stronger and more fun!

Ryushin Juku offers not only regular training, but also joint training, parent-child karate experience, joint training camps, BBQs, swimming pools, New Year’s tryouts, and many other fun events.

The kind of leader we aim for

There was a time when I worked in the childcare industry. At that time, I wondered what kind of sensei would be attractive to children, and I began to see the ideal image I had when I was a child: “I wish I had a sensei like that”.
When it came time to open a dojo, I decided that the following was what I wanted to do
I’m glad I had a teacher like this when I was a kid! It means to be the kind of teacher that makes children feel that they can be a good teacher.
Test scores and tournament results are important, but Ryushinjuku and I will aim to be a dojo and teacher that will be remembered more than a record (and of course, strength).
