What Link & Communication does

Wellmira Inc. (formerly Link & Communication / 株式会社リンクアンドコミュニケーション) is a Tokyo-based Japanese healthtech company founded on 25 July 2002 by Watanabe Toshinari (still Representative Director, President and CEO) and headquartered in Chiyoda-ku. It builds PHR (Personal Health Record)-centric AI applications that deliver personalized guidance on diet, exercise and sleep, combining an in-house evidence-based algorithm with an AI engine that produces more than 200 million personalized advice variants. The flagship consumer product is the AI health app CaloMama Plus (カロママ プラス), with RenoBody (リノボディ) as its corporate walking/pedometer application and an Online Specific Health Guidance service that layers registered-dietitian and public-health-nurse counseling on top of the app for Japan's mandatory 特定保健指導 workflow. In January 2024 the company integrated the healthcare business of Neos Corporation, added the legacy Karada Manager to its portfolio and rebranded as Wellmira; TechMira Holdings sits as the top major shareholder and has installed its executives as Chairman, Director and Auditor, indicating a parent-strategic control structure.

The company sells through a hybrid B2B/B2C model with no publicly disclosed list pricing. B2B go-to-market is field/enterprise sales to Japanese corporations, kenpo health-insurance societies and municipalities/smart-city programs — exemplified by the 2026 'Yaizu Health Mileage de Gohoubi Campaign' — plus channel and partner recruitment of dietitians, doctors and web operators. B2C distribution runs through the CaloMama consumer app site and the RenoBody app. Around these, Wellmira monetizes (i) CaloMama Plus as recurring B2B SaaS for specific-health-guidance and corporate wellness, (ii) RenoBody as a managed walking-event service, (iii) outsourced healthcare app-development engagements that monetize its own product know-how, (iv) co-developed food/health content media including Toushitsu.jp, Olive Oil Life and kawaru.biz / かわPro for professional dietitians, and (v) a CaloMama Supporters consumer CRM channel for food manufacturers and retailers. The platform is recognized as a 健康経営優良法人 (Certified Health & Productivity Management Outstanding Organization) under Japan's METI-administered program, was selected for the METI/AIST 'KENKO Investment for Health' showcase at SPORTEC Thailand 2026, and is backed by a major-shareholder roster that includes Tokio Marine & Nichido, Meiji Yasuda Life Insurance, Kowa, Mizuho Securities, Mitsubishi UFJ Capital, SBI Investment, Toho Holdings and Relo Club.
