Takashi Kato, Chairman


Hello. My name is Takashi Kato.

I have been engaged in all kinds of Surgery (thyroid glands, mammary glands, esophageal diseases, gastrointestinal diseases, hepatobiliary and pancreatic diseases, vascular diseases, and endoscopic surgery), emergency, and anesthesia works for about 20 years.

In addition, I also have the experience as the director of a clinic in a rural area.

My specialty is esophageal diseases, but people could call me a "medical generalist".

Therefore, I am confident in skills to address all kinds of diseases.

The reason why I have worked to date as a doctor is that patients became healthy physically and mentally, and shared that joy with me. That is my greatest pleasure.

I am happy to help you with full force so that all of you can send a prosperous life.

Please feel free to consult us anything!

Physician certified by Japan Gastroenterological Endoscopy SocietyDirector of Department of Gastroenterology


The 1st cause of death is cancer in Japan. Among that, colon cancer, lung cancer, and gastric cancer are the top 3 in both men and women.
There are many gastrointestinal cancers.
If cancer is found at an early stage, the possibility of curing increases. Early detection and early treatment are very important. We recommend to take a regular medical checkup.

I have engaged only in the Department of Gastrointestinal Medicine at general hospitals. I was certified by The Japanese Society of Gastroenterology and Japan Gastroenterological Endoscopy Society. I have performed more than 6,000 cases of Gastroenterology including gastric cameras and colon cameras.
Most gastric cancer is said to be caused by H. pylori. To use health insurance, firstly we need a gastric camera for checking H. pylori.
Colon cancer is said to occur by polyps first. These polyps will be cancerous with growth.Therefore, we recommend to take a colon camera at an early stage to find and treat polyps early in order to decrease the risk of colon cancer.
If you have any concern, such as "I have never taken a checkup", "I would like to take a gastric camera or colon camera, but I am scared...""How is popular transnasal endoscopy?", please contact us first.
We are also waiting for those who having concerns about symptoms of the body.

I returned from Chang Gung Memorial Hospital, one of the largest hospitals in the world in Taiwan in the spring of 2016.At the place where plastic surgeons all over the world gathers and compete with each other, I had challenged how much the techniques of a Japanese plastic surgeon can work through excited discussions, surgeries, and researches for 1 year.

In the fellowship with ups and downs, I faced and seriously considered the problems which the Japanese medical system inherently has, while confirming Japanese technologies and knowledge. The answer is that I will challenge to the beauty industry.

There is no clear line between plastic surgery and cosmetic surgery overseas, and treatments for both of diseases and beauty are provided seamlessly.
Medical professionals will provide the service which the persons receiving service selected.The Japanese health insurance system clearly divides treatments into hospitals treating diseases and beauty care seeking beauty.On the other hand, if you have a disease or cosmetic complex, you cannot draw a line between diseases and beauty.For example, a patient with a cleft lip wants to make his/her nose higher and beautiful, a patient with breast cancer wants to treat the sagging breast on the healthy side for balancing, and a patient with ptosis wants to make a forehead lift in order to lift sagging eyebrows. There is no clear criteria for these requests now, and that confuses the medical industry.The ultimate goal of both treatments is to seek quality of life (QOL) to "spend social life with smile and confidence".

However, how about treatments for those who between diseases and beauty? I believe that to provide more treatments for them is my lifetime job.

The SBC group has dreams. I agree with their dreams, and I think I can pursue my dream here.

I have actively reported my researches by papers, and at presentations at academic conferences based on my past experiences.We have a pride that we are doing the right things, and we confirm that by objective evaluation. Thereby, we can enhance ourselves.

It will not change forever.We can achieve good results based on correct analysis and clear logic.Then, we will strictly examine the results, and make people receiving the service happy. It is my belief.
