Because of my close relationship with a house builder, I learned repair techniques and began to receive repair requests.

Through the repair and existing business, we are able to get to know many construction companies, which leads to the expansion of our existing business.

I moved from Tokyo to Miyakojima City, Okinawa, and entered the repair business as a newcomer. There is no competition on the island,

I was able to become the only repairman on the island, earning 800,000 yen per month.

I am in the real estate business. We don’t need a repair company,
We are now able to do the repair work on our own, which is a big help to us because we are spending less money.

Here are some of feedback and review from our students.

This student is from Tottori, Japan. He works for a cleaning company and attended our repair school in order to introduce the repair business as a new business.

Course content and cost

I believe that high or low prices are a matter of different perspectives,
I think it is very inexpensive to learn both the technical and mental aspects of doing business professionally in the course I took.

About the course content

The doctor(*instructor?) was able to identify my own character and to worked with me until I was satisfied.

I was able to understand the content of the lecture as the instructor made it easy for me to understand.

Did you learn what you wanted to learn?

I told Mr. Hirano in advance what I wanted to learn, and he taught me plenty of cases that might come up in my work in the future.

Is it hard to practice on your own?

From the time I learned to the next repair class,
I practiced what I had learned repeatedly at home to make my body memorize what I had learned.

I have fond memories of bringing the colored wood to the atelier on the bullet train or subway each time.

It’s not a rigid image of independent practice; this was also a part of practicing the actual work. Or else, you may not have pictured the image of the actual flow of the pattern just by being taught verbally.

We are human beings and we tend to forget things easily. That’s why it was even easier to under stand when I reviewed while moving!

Is it hard to stay motivated?

In order not to lose my motivation, I reported what I had learned and asked for clarifications on things I could not comprehend as soon as possible and received further instructions on how to proceed.

The instructor’s casual and friendly conversation with me motivated me to keep going.

Finally, we look forward to working with you in these times of twists and turns.


This student comes from Nagasaki Prefecture.

A housecleaning and dressmaking business owner enrolled in the repair school in order to start a new repair business.

Did you learn what you wanted to learn?{

I learned more than enough.

About Pricing

Before taking the course, I thought it would be expensive, but the one-on-one instruction taught me the skills I needed.

After taking the course, I didn’t think it was expensive at all and felt it was more than worth it.

About the Instructor

I am glad I chose this school because the instructors are not stiff and crafty, but soft and receptive, making it easy to ask questions.

Follow-up services after the course

I ask questions online about things I don’t understand and receive accurate advice. They also respond immediately to my requests regarding tools.

This student comes from Okayama Prefecture. He has been working for a construction company and attended the repair school.

Do you think taking the Repair School will help you in your work?

It seems to lead to work, and we have already received several requests.

Did you learn what you wanted to learn?

I was able to learn what I wanted to learn, and they were better than the repairers I have arranged for myself.

Course Content and Pricing

I know the price seems high, but I think it is actually low. If you do a neat job and work productively, I think you can get what your money is worth quickly.

Impressions about the Instructor

He was easy to talk to and was very helpful in quickly answering questions I asked.


This student is from Ishikawa, Japan. He is a scaffolding shop owner and attended the repair school.

Did you learn what you wanted to learn?

I have been working on scaffolding and originally decided to take the course because I was interested in repairing exterior walls and sashes.

When I took the course, I learned that most of the repairs were to wood and the interior of the house.

It was refreshing for me to learn more about the repair profession, which I had never experienced before, and I was able to get more and more involved in it.

I am very satisfied with the course content, which was more than I wanted to learn.

About Pricing

As for the price, to be honest, it is a courageous amount of money, and I can’t say anything too easy about it, but I thought it was a reasonable price and rather inexpensive if you can learn such skills.

However, I thought it was cheap if I could acquire such a high level of skills for a reasonable price.

I would like to put it into practice and make use of the skills I have learned.

About the Instructor

I really appreciate all the help I received from the instructors. I started from scratch,

They created an environment that made it very easy for me to meet, talk, and take classes, and I was able to enjoy learning.

Follow-up services after the course

I have finished the course and am now ready to start, I was able to start my business with peace of mind, thanks to your advice and
encouragement to contact you at any time.

Finally, when I applied and took the course for the first time, I was very anxious and worried, but once again, I am grateful for this encounter!
Thank you very much for teaching me so many different repair methods and techniques. I am still inexperienced, but will continue to practice and gain experience.

We look forward to working with you again in the future!
