About the Clinic

What is GoCLN Longevity Clinic?: GoCLN Longevity Clinic is a preventive and longevity medicine clinic in Roppongi, Tokyo. We conduct structured diagnostic assessments and develop personalized protocols designed to identify and address health risks before they progress to disease.
How is GoCLN Longevity Clinic different from a traditional hospital or Ningen Dock?: A standard Ningen Dock is designed for disease screening — it asks whether disease is present today. Our MIRAI programmes are designed for risk identification — it asks what is likely to develop over the next 10 to 20 years, and what can be done now to change that trajectory. Our assessments include markers, imaging, and analytic tools that most general health checks do not cover.
Is GoCLN Longevity Clinic covered by Japanese national health insurance?: Yes for sickness related consultations and some exams. However some preventive exams and longevity medicine treatments are outside the scope of the national insurance system. Some services at GoCLN Longevity Clinic are private (jiyū shinryō / 自由診療). Receipts are provided and may be submitted to private insurance or employer wellness programs where applicable.
Do I need a referral?: No referral is required. Patients may book an initial consultation directly.
Is English support available?: Yes. Physicians and Health coaches and front-desk staff are bilingual in Japanese and English. Clinical reports are available in both languages.

What is the MIRAI Program?: MIRAI is our comprehensive baseline diagnostic assessment. It includes advanced laboratory testing, imaging, body composition analysis, cardiovascular evaluation, biological age assessment, and an in-depth physician consultation. It is offered in three tiers with increasing depth of analysis.
How long does a MIRAI assessment take?: The in-clinic portion typically takes 3 to 5 hours depending on the tier selected. Results are prepared over 15 to 30 business days, after which a follow-up consultation is scheduled to review findings and protocol.
How often should I repeat the assessment?: Most patients repeat the core diagnostic annually. Certain markers may be monitored more frequently — typically every 3 to 6 months — depending on the protocol.
Can I choose individual tests instead of a full program?: Yes. À la carte diagnostics and single consultations are available. The full MIRAI program is recommended for patients seeking a complete baseline.

Do you prescribe hormone replacement therapy?: When clinically indicated and supported by laboratory data, yes. Hormone optimization is conducted under physician supervision, with follow-up monitoring as a core part of the protocol.
Do you offer IV therapy?: Yes. IV vitamins and nutrient therapy is available on an individualized basis.
Do you offer peptide or regenerative therapies?: Select peptide and regenerative protocols may be offered when supported by scientific evidence and appropriate clinical indications. Before any treatment decision is made, all potential benefits, risks, and expected outcomes are discussed in detail with the patient.
Are your therapies approved in Japan?: All therapies offered at GoCLN are within the bounds of Japanese medical regulation. Certain protocols are administered under a physician's responsibility under Japan's jiyū shinryō framework; informed consent is obtained in every case.

How much does the MIRAI program cost?: The MIRAI Program is personalized to each individual's health profile, goals, and clinical needs. Following an initial inquiry, our team will help determine which MIRAI Program is most appropriate for you and provide the corresponding pricing and program details. Please contact the clinic to arrange a consultation.
Is there a membership requirement?: No. GoCLN Longevity Clinic does not require a membership fee or annual retainer. Patients pay for the services they receive.
What payment methods are accepted?: We accept major credit cards and e-money payments.
Do you offer corporate or executive programs?: Yes. We provide structured executive health assessments for companies. Please contact the clinic for corporate inquiries.

How is my medical data stored?: All clinical data is stored in accordance with Japan's Act on the Protection of Personal Information (APPI) and medical record retention requirements. The GoCLN Longevity Clinic digital platform uses encrypted storage and access controls consistent with medical data standards.
Who has access to my records?: Your records are accessible only to the clinicians directly involved in your care and to authorized clinic administrative staff. Data is never shared with third parties without your explicit written consent.
