Omotesando Helene Clinic in Tokyo, Japan, offers autologous stem cell therapy for erectile dysfunction; initial counseling is free. The clinic holds ISO 9001 certification and Japan’s MHLW approval for this treatment plan.
Dr. Takaaki Matsuoka, MD, PhD, specializes in regenerative medicine and stem cell therapy. He has over 20 years of experience and is a Diplomate of the American Board of Regenerative Medicine.
The clinic’s MHLW plan, PB3240038, covers MSC treatment for erectile dysfunction. The cells are cultured in HELENE Medium, a serum-free medium registered with the FDA’s Drug Master File. An ISO Class 5 cleanroom and barcode tracking are used during processing. Takara Bio conducts third-party sterility and non-tumorigenicity testing.
The clinic says MSCs may support blood vessel growth and reduce inflammation in the corpus cavernosum, the erectile tissue. It reports that effects may develop over 3 to 6 months. The clinic has treated 17,000+ stem cell cases, with no serious complications reported.
Patients can request a consultation through Bookimed to discuss whether assessment or treatment may suit their needs.

Omotesando Helene Clinic is a private regenerative medicine facility in Tokyo's Omotesando district. Dr. Matsuoka founded it in 2014. The clinic specializes in stem cell therapy using autologous mesenchymal stem cells (MSCs). These cells come from the patient's own body to support tissue repair and reduce inflammation. The clinic operates under Japan's Regenerative Medicine Provision Plan framework, approved by the Ministry of Health, Labour and Welfare.
In 2017, the clinic became the first stem cell facility worldwide to receive GCR (Global Clinic Rating) certification. It also maintains ISO 9001 certification for quality management. MEDTECH Outlook APAC named it a Top Regenerative Medicine Solution Provider in 2025.
Between 2013 and 2026, the clinic treated more than 15,000 patients. Several international awards reflect its quality standards:
The clinic holds multiple MHLW authorizations for manufacturing cell-processed products. These licenses confirm compliance with strict Japanese regulatory standards for biological safety.
Specialists treat 15 different medical conditions with autologous stem cell therapy. The process starts with collecting the patient's own MSCs. These cells are then cultivated and activated before administration. Physicians adjust the cell dosage based on each patient's constitution and health goals.
This personalized approach covers several key areas:
The medical team includes Dr. Takaaki Matsuoka, the first physician to receive Stem Cell IV Therapy under Japan's Regenerative Medicine Act. Professor Ravindra Gupta from the University of Cambridge serves as an advisor – Time Magazine named him one of its most influential people. Dr. Nana Kobayashi, certified by the Japan Society for Regenerative Medicine, oversees clinical regenerative plans.
The clinic has an integrated Omotesando Cell Culture Lab, also called a Cell Processing Center (CPC). This laboratory handles cell collection, storage, culture, and testing in one location. A barcode system tracks every cell sample throughout cultivation. The lab uses an ISO Class 5 clean air environment to prevent contamination.
Key technologies include the proprietary HELENE Medium, a serum-free culture medium with FDA DMF registration. The laboratory can cultivate up to 2.25 billion MSCs within one month. The clinic also publishes research on the long-term safety of high-dose intravenous stem cell therapy.
Omotesando Helene Clinic offers full support for patients traveling from abroad. Multilingual interpreters assist during consultations and treatment. Support is available in:
Patients can schedule online pre-travel consultations to discuss their medical history before arriving in Japan. After treatment, the clinic provides a dedicated recovery area and emergency contact guidance. Staff give specific aftercare instructions, including activity limits and home care steps. Long-term maintenance plans are also part of post-treatment support.
