CoreHealth

What CoreHealth does

CoreHealth Inc. (株式会社CoreHealth) is a Japanese health-tech startup founded September 13, 2023, by Professor Kobayashi Hiroshi of Tokyo University of Science, who serves as Board Chairman. The company is an academic spin-off that was officially certified as a Tokyo University of Science venture startup on October 26, 2023, and is operated by President and Representative Director Yoshida Tomya. CoreHealth is structurally distinct from Innophys Co., Ltd., the founder's earlier 2013 commercialization vehicle for industrial Muscle Suit applications in logistics and caregiving; CoreHealth exclusively targets healthcare, wellness, and posture-correction use cases, operating under license to the Muscle Suit trademark held by Innophys. The headquarters is located at Cross Point Iidabashi in Chiyoda-ku, Tokyo, and the company serves the Japanese domestic market only.

CoreHealth's product platform centers on Muscle Suit CARE, a wearable posture-correction device powered by McKibben-type pneumatic artificial muscles. The proprietary McKibben actuator — EPDM rubber covered with polyester monofilament — weighs approximately 100 grams and generates contractile force exceeding 2,000 times its own weight when supplied with compressed air, with validated durability of more than 1 million cycles under a 2,000N load. The mechanism uses a back-frame and thigh-frame architecture: compressed air contracts the artificial muscle, rotating the back frame around a pivot axis to transmit reaction force into the thigh pads, allowing the wearer to maintain upright posture and lift without bending the knees. Claimed health effects include pelvic and spinal alignment correction, expanded hip joint range of motion, opened thoracic cavity for improved breathing, stabilized center of gravity for fall prevention, inner muscle strengthening, and back pain relief. The device achieves posture correction on donning with a claimed setup time of approximately 10 seconds.

The business model is hardware sales of the Muscle Suit CARE device supplemented by professional consultation, demo, and implementation services handled through a direct website consultation form. Pricing is not publicly disclosed. Go-to-market is sales-led and event-driven, targeting six verticals: care facilities, training gyms, pilates studios, yoga studios, physical therapy clinics, and chiropractic offices. Demand generation is executed primarily through earned media (FNN Live News It! and FNN Prime Online features in October 2024), industry exhibitions (beautyworld JAPAN TOKYO April 2025; CareTEX Tokyo July 2025), and organic social channels on Instagram, TikTok, and YouTube. No funding rounds, revenue figures, headcount, or institutional investors are disclosed in the available data.

Core offering

CoreHealth sells the Muscle Suit CARE, a healthcare-focused wearable device that uses McKibben-type pneumatic artificial muscles to provide ultra-quick posture correction, spinal alignment, joint mobility expansion, breathing improvement, and back pain relief. The company also provides consultation and implementation services to care facilities, fitness studios, and rehabilitation clinics in Japan. Its purpose is to extend healthy life expectancy and support independent living in Japan's super-aging society.

Product overview

CoreHealth offers a unified product portfolio centered on the Muscle Suit technology for posture correction and physical support. The core offering is マッスルスーツCARE (Muscle Suit CARE), a healthcare application that uses pneumatic McKibben-type artificial muscles to provide ultra-quick posture correction. The underlying マッスルスーツ (Muscle Suit) is a waist-assist device originally developed for worker support, now adapted for healthcare use. The McKibben-type artificial muscle is the foundational technology enabling all products—providing powerful yet lightweight actuation for posture correction, joint support, and physical assistance.
