Life Work

"Remove distortion"

The goal is to create preventive and therapeutic methods for joint distortion throughout the body, and to spread them so that everyone can use them easily. Foot distortion leads to hallux valgus, knee distortion leads to knee osteoarthritis, and pelvic distortion leads to sacroiliac joint pain and lumbar spine disease. We will develop devices, exercises, and treatment methods that use hands to reliably prevent these.

In order to eliminate distortion, we have developed various rear line equipment. Specifically, there are the following products. We would like to use these to contribute to the creation of a society in which everyone can easily tackle distortions in the same way that toothbrushing is used to prevent tooth decay.

"Medical of Healing"

It is undeveloped land. The technique of finding adhesions in the body with fingertips is called "precise palpation," and I acquired the trademark for it. Using this, not only muscles and bones, but also nerve and blood vessel pain can be found, and the state of internal organs can be grasped and treated. Menstrual cramps, constipation, urinary incontinence, limited range of motion due to joint adhesion, muscle adhesion that causes muscle weakness, etc. can be palpated and treated.

I am not satisfied with just popularizing this technique of palpation and inter-organizational release. Based on past treatment experiences, we have obtained many new findings that have not even been the subject of medical research. For example, touching the sympathetic nerve on the back of the stomach induces a headache, and inserting a finger between the fallopian tube and the pudendal femoral nerve induces abdominal pain similar to menstrual cramps. These are completely new findings that have not been known in conventional medicine. I would like to advance my research with new knowledge as my research theme, and would like to promote joint research with doctors and researchers in various fields.

Past Workplaces

●Y)hama Sports Medical Science Center (1998-2003)

After graduating from graduate school, I joined the Yokohama City Sports Medical Science Center, which was established at that time. I had no work experience other than training, but the late Mr. Haruo Takazawa (director of the center) welcomed me as the director of the physical therapy room. Mr. Hideyuki Miki (the center → Totsuka Nishiguchi Orthopedic Surgery) trusted me, and although there were countless small mistakes, I was able to devote myself to clinical practice to my heart's content.

I was inspired by the content of a lecture given by Mark DeCarlo (Team Rehabilitation) at the 1999 WCPT (World Congress of Physiotherapists) symposium. After observing Dr. Shelboune's surgery and postoperative rehabilitation for a week, I was keenly aware of the importance of achieving full extension. I have published a serial article in Sports Medicine under the title "How to Perceive Syndrome" about the idea of ​​giving top priority to recovery (or correction) of complete range of motion and alignment. The late Mr. Terufumi Seike, who was the editor-in-chief at the time, took care of me for about 30 years, starting when I was 20, and gave me many opportunities to write. He passed away in December 2019, which is a shame.

The treatment policy I had in mind when I was 30 years old was gradually organized, and in 2008, I was able to summarize it as the REALLINE concept. If you think about it, the experiences you get in your 20s, free thinking, the accumulation of small failures, and the opportunity to put them all together form your lifework. I would like to guide my juniors with a strong awareness of giving young people in their 20s a chance to fail.


From June 2003 to March 2006, I studied abroad in the United States. I had been to the United States many times, including traveling alone, so I think I was able to take it optimistically, even if there were various minor problems. During this period, I believe that I was able to acquire the “breakthrough power” to overcome all obstacles and move forward despite all kinds of obstacles.

During my study abroad, I am indebted to Mr. Joel Bach of the University of Colorado and Mr. Scott Banks of the University of Florida. In particular, Scott taught me analysis techniques and provided me with software so that I could continue my joint dynamics analysis research after returning to Japan.

●Hiroshima International University (2006-2019)

In April 2006, I entered Hiroshima International University and was responsible for the training of physical therapists. From the time she joined the laboratory, the activity of the laboratory was started mainly by undergraduate students with the goal of training therapist researchers who can be active internationally in both research and clinical practice. It became possible to recruit graduate students in the Graduate School of Medical Engineering, and there were times when the number of graduate students was 5-8 at any given time, and up to 10 at one time. Thanks to their leadership, I was able to publish more than 70 peer-reviewed papers during my 14-year tenure. Graduate school alumni are active in universities and clinical settings, and are leading their lives strongly as leaders in their respective specialized fields.

During this time, I was in charge of not only graduate school education but also undergraduate education. I was in charge of classes such as physical therapy research methods, sports injury treatment, and exercise therapy. In addition, I was able to gain a certain understanding of university management by experiencing a range of committee activities, including clinical training support, career support, multidisciplinary collaboration, and entrance examination work.

I will be graduating from the university at the end of March 2020. The reason for advancing to the next stage was the decision to increase the number of students in the Department of Physical Therapy (from 60 to 80). As a university manager, I understand that it is only natural to increase the number of students in majors with many applicants, but I sensed that this was not my job. It was decided that it would be impossible to train young therapists with a philosophy, instill advanced techniques, and promote research published in international journals, while educating 80 undergraduate students at the same time. I apologize to the undergraduate students, but from April 2020 onwards, I would like to concentrate on my postgraduate education.

●GLAB INC.(2008- )

Established GLAB Co., Ltd. on June 26, 2008 and assumed the position of CEO. At that time, I was working with President Terasaka of Kyowa Rubber Co., Ltd. on the development of rear line insoles. With a 50% investment from Josho Gakuen, the parent organization of Hiroshima International University, we were able to set sail as a university-launched venture. This was a powerful boost in getting grants and collaborating with others.
