The Tree-shinkai Medical Corporation Island Tower Clinic Shinjuku, located in Nishi-Shinjuku, Shinjuku Ward, Tokyo, is a specialized clinic for autologous hair transplantation. The clinic boasts over 39,000 treatment cases, achieving the No.1 market share in Japan. It records a high graft survival rate of 94%, with its track record and reliability as its strengths. The clinic has developed the proprietary "i-Direct" technique, commanding over 54% market share in the domestic market. This technique combines graft extraction, recipient site creation, and implantation, enhancing design aesthetics and graft survival rates. Using a self-developed tube punch and pneumatic implanters, the clinic minimizes physical burden on patients and damage to hair follicles. Adopting a non-surgical extraction method and "No-Shave Direct" first introduced in Japan, there is no need to shave hair in advance, enabling treatment with postoperative appearance consideration. The clinic offers transportation and accommodation expense support for patients traveling from afar, as well as a full refund guarantee if no hair growth is observed. Credit cards and electronic payments are accepted.
