Dojin Clinic, located in Fukuoka, is a clinic that offers immune cell therapy as self-pay (non-insured) treatment. Its efficacy has not been established, and suitability is determined by a physician on an individual basis.

The Foundation: Dr. Tsuneo Kuramochi (deceased)’s Advance

The well-known "Six-Cell Combination Immunotherapy" was originally developed by the late Dr. Tsuneo Kuramochi, who researched cancer immunology. According to the clinic, the technique, which activates six types of immune cells at the same time, is patented in Japan and Korea.

Current Leadership: Dr. Toshihide Aso

Today, the clinic is directed by Dr. Toshihide Aso, a distinguished graduate of the Kyushu University School of Medicine. With an extensive background in cardiovascular surgery and international medical relief, Dr. Aso brings a global perspective and rigorous scientific standards to the clinic.

Under Dr. Aso’s guidance, Dojin Clinic continues to refine and implement Dr. Kuramochi’s patented protocols, with cell preparation carried out in the clinic's Cell Processing Center (CPC).

Why Choose Dojin Clinic?

  • Six Cell Types: Simultaneously activates γδT cells, NK cells, NKT cells, CTLs, Dendritic Cells (DC), and Helper T cells.
