N2Clinic Ginza

N2Clinic Ginza opened in 2015, at the time when regenerative medicine began. Since then, we have accumulated a large number of treatment achievements as a medical institution specializing in regenerative medicine. We have gained the trust of many guests from Japan and abroad. We relocated our clinic from Shirokane-Takanawa to Ginza in March 2021. In addition, we have opened two new clinics in Tokyo, one in Hotel Chinzanso Tokyo and another in Yotsuya.

N2Clinic Ginza will continue to provide the most advanced regenerative medicine with an emphasis on safety.

Implementation System for Regenerative Medicine

Medical institutions that provide regenerative medicine using cultured cells must perform a process to prepare a plan for the provision of regenerative medicine for each regenerative medical technology they intend to implement. This process must be reviewed by Certified Special Committee for Regenerative Medicine approved by the Ministry of Health, Labor and Welfare to determine whether it complies with the standards.

The N2Clinic is a medical institution specializing in regenerative medicine that has submitted a regenerative medicine provision plan to the Kanto-Shinetsu Regional Bureau of Health and Welfare through this process and obtained a code of the plan.

Regenerative medicine

We provide stem cell therapy (Class II Regenerative Medicine) using adipose-derived stem cells. In addition to cell-based regenerative medicine, we also provide culture supernatant therapy by using functional components secreted by stem cells.

Experienced physicians in regenerative medicine who are active on the front lines will propose highly safe regenerative medicine.

  • Stem Cell Therapy
    Your own adipose-derived stem cells are multiplied by cell culture and administered by intravenous injection or local injection, which is expected to repair and regenerate damaged tissues.

  • Immunotherapy
    mmunity can be enhanced by administering various immune cells such as NK cells, T cells, and dendric cells that have been proliferated and activated by cell culture treatment.

  • Stem Cell Culture Supernatant
    Functional components such as various cytokines and exosomes secreted by stem cells are applied for tissue repair and anti-aging medicine.

Stem Cell Therapy

This is a regenerative medicine that uses stem cells from adipose tissue. Since the cells are your own, there is no rejection, and the treatment is highly safe.


Blood tests and explanation of treatment
Blood test and explanation of the treatment will be given by a physician before the collection of adipose tissue.

A very small amount of adipose tissue is collected from the abdomen by liposuction, which minimizes damage to the body. The procedure is performed by an experienced plastic surgeon certified by the Japanese Orthopedic Association.


The collected adipose tissue is immediately transported to a cell processing facility under optimal storage conditions. A very small amount of the stem cells contained in the tissue are isolated with extremely high precision and multiplied tens of millions of times by cell culturing treatment. In order not to impair the tissue repair function of the stem cells, a precise cell management environment is maintained.

You can take a shower from the next day.


No more restrictions on bathing and exercise.


The stem cells are cultured and ready to be administered for the first time. The stem cells will be cryopreserved until the day of administration to preserve the quality, after which they can be administered at any time.

For the second and subsequent doses, the frozen stem cells can be thawed and cultured to achieve the target number of cells on the scheduled day of administration. Cell culture allows for a highly efficient increase in the number of cells, making it possible to administer stem cells multiple times in a single liposuction.



Depending on the severity of the symptoms, we recommend a second and subsequent treatment after an interval of one to three months. However, we suggest a treatment schedule that suits the physical condition and convenience of our guests.
