Senken

What Senken does

Senken (株式会社センケン) is a Takamatsu, Kagawa-based Japanese healthcare consulting company founded on August 27, 2019 by registered dietitian Iwaki Hirohisa (岩木博久). The firm operates an integrated health management portfolio anchored by three pillars: the certified Nutrition Care Station (認定栄養ケア・ステーション) — the first and only Japan Dietitian Association credentialed facility of its kind in Kagawa Prefecture; the proprietary Health Core Coaching (ヘルス・コア・コーチング) methodology that combines nutrition consultation with coaching techniques and autonomic nervous system measurement; and the Wellnesta health support studio, which integrates high-precision HRV measurement devices, the Master V3 fully-automatic spinal adjustment machine, and Shikoku's only plasma therapy center. The company holds Shikoku-exclusive distribution rights for YKC's condiView, MindViewer, and TAS9View medical-grade autonomic nervous system measurement devices, and distributes complementary curated products from PMC (Alpha Stream far-infrared bedding), Alcoyiris (Amazon-sourced Omega-3 and protein), Okinawa Sea Salt Research Institute, and Genmai Enzyme.

The company serves four primary customer segments: SME owners/managers seeking corporate health management consulting; athletes and sports teams requiring performance nutrition and autonomic measurement; catering and welfare institutions needing menu planning, nutrition calculations, and operational improvement consulting; and individual consumers pursuing personalized one-on-one health coaching. Revenue is generated across roughly ten streams including one-on-one coaching subscriptions (27,000-90,000 yen for 1-6 month plans), a Health Core Coach certification training course (65,000 yen), nutrition care station services (menu planning at 30,000 yen/month, instructor dispatch at 50,000-100,000 yen), outcome-based cafeteria consulting (30,000 yen/month plus 15% of profit uplift), and curated product sales. Go-to-market is sales-led with an event-driven overlay: direct one-on-one delivery via Zoom/Skype/phone or in-person at Wellnesta, supplemented by online introductory seminars (e.g., a 2020 seminar to a Saga Prefecture customer) and content marketing through a blog, newsletter, Twitter, and Facebook presence.

The business operates from a single Takamatsu headquarters with a small team of approximately 2-5 registered dietitians (with one additional hire actively being recruited). The company is founder-owned, has no parent entity, and has no disclosed institutional investment beyond a 2022 FinAccelerate accelerator engagement with no reported capital. Geographic focus is the Shikoku region of Japan for in-person delivery, with online channels enabling individual consumer reach nationwide.
