Your Health, Measured.
Your Future, Designed.
GoCLN is a physician-led longevity clinic in Roppongi, Tokyo. We combine advanced diagnostics, biological age analysis, and personalized intervention to detect risk years before symptoms appear.
Evidence-based preventive medicine.
Conventional healthcare intervenes after disease manifests. We identify risk at its earliest detectable stage — often 10 to 20 years before symptoms develop. This model shifts the focus from treating disease to preserving long-term health through early detection, continuous monitoring, and precision intervention.
- 01
Comprehensive Diagnostic Assessment
Up to 200 biomarkers across cardiovascular, metabolic, hormonal, inflammatory, and organ-system categories. Advanced blood panels, DEXA body composition, cardiovascular imaging, vascular assessment, and functional performance testing — every test selected for clinical relevance.
- 02
Integrated Analysis & Biological Age
Our physicians synthesize all data into a unified clinical picture. A validated platform developed by a Stanford biomathematician calculates the biological age of individual organ systems and compares them against 6,000+ patients — identifying which systems are aging fastest.
- 03
Personalized Intervention & Follow-Up
Each patient receives a structured, evidence-based action plan addressing specific risk factors. Interventions may include nutritional optimization, exercise prescription, sleep architecture improvement, hormone management, or targeted therapeutics. Progress is tracked longitudinally.
Your future health, starting today.
MIRAI is our flagship executive health assessment — designed for individuals who want more than a standard screening. A complete, medically rigorous evaluation of your current health trajectory and a clear plan to improve it.
The name reflects our philosophy: your health future is not fixed. It can be measured, understood, and changed.
What the assessment includes
Cardiovascular Risk
Advanced lipid profiling (ApoB, Lp(a), small-dense LDL), hs-CRP, homocysteine, ECG, vascular age measurement, and carotid intima-media thickness ultrasound — detecting atherosclerotic risk years before standard tests.
Metabolic & Endocrine
Fasting glucose, HbA1c, insulin, HOMA-IR, full thyroid panel with autoimmunity markers, and comprehensive hormone assessment (testosterone, estradiol, cortisol, IGF-1, SHBG).
Body Composition & Performance
DEXA scan for bone density, lean mass, and visceral fat. Grip strength, cardiovascular fitness, mobility assessment — among the strongest predictors of all-cause mortality.
Organ Function & Cancer Screening
Full hepatic and renal panels, CBC with inflammatory ratios, tumor markers (PSA, CA 19-9), abdominal ultrasound, urinalysis, and stool analysis with gut inflammation markers.
Biological Age Profiling
Organ-system biological age — cardiovascular, pulmonary, neurocognitive, musculoskeletal — compared against your chronological age. This identifies your body's weakest links for targeted intervention.
Physician Consultation & Action Plan
A dedicated consultation reviewing all findings as an integrated health narrative — not isolated numbers. You leave with a structured, prioritized, personal action plan.

Three pillars of healthspan.
We integrate the three pillars the evidence consistently shows matter most: sleep, nutrition, and exercise. Each is assessed, prescribed, and monitored as rigorously as any pharmaceutical intervention.
Sleep Medicine
Poor sleep architecture accelerates cardiovascular risk, impairs metabolic function, and degrades cognition. We assess patterns and incorporate circadian rhythm management, behavioral protocols, and clinical monitoring.
Nutrition Science
Data-driven and individualized. Based on your metabolic markers, micronutrient levels, inflammatory indicators, and gut health — our team designs a strategy that addresses your specific physiology.
Exercise Prescription
Cardiorespiratory fitness (VO₂ max) and muscular strength are the single strongest predictors of longevity. We assess your functional capacity and prescribe a structured program with in-house expert coaching.
Targeted optimization.
Based on diagnostic findings, our physicians may recommend targeted therapeutic interventions. All therapies are evidence-based, physician-supervised, and prescribed only when clinically indicated.
- Hormone OptimizationTestosterone, estrogen, and thyroid management guided by comprehensive laboratory data and clinical assessment.
- IV TherapyTargeted micronutrient infusion protocols including NAD⁺, glutathione, and custom formulations based on individual deficiency profiles.
- Peptide TherapyClinically supervised peptide protocols for metabolic support, recovery, and physiological optimization, including GLP-1 agonist management.
- Regenerative MedicinePRP therapy for joint, tissue, and hair restoration. Advanced stem cell therapy programs for systemic and localized regeneration.
- Lifestyle CoachingOngoing access to longevity coaches, nutritionists, and exercise specialists as part of membership programs.
All therapeutic interventions require prior diagnostic assessment and physician clearance.
The GoCLN Health Platform.
Every patient receives access to a secure digital platform where all results, biological age assessments, and recommendations are centralized. Biomarker trends are tracked longitudinally. The platform supports wearable device integration for ongoing sleep, activity, and metabolic monitoring between visits.
Designed for precision and privacy.
Located in Roppongi, Tokyo. Purpose-designed for comprehensive diagnostics — with dedicated zones for blood collection, imaging, cardiovascular testing, body composition, consultation, and therapeutic treatments. A low-volume model ensures unhurried, thorough care.
Join a new model of clinical practice.
GoCLN is building a clinical team at the forefront of preventive and longevity medicine in Japan. We seek physicians, nurses, and technicians who share our commitment to evidence-based practice and the emerging discipline of healthspan medicine.
