What Personal Health Tech does

Personal Health Tech is a Japanese healthcare DX company founded in February 2022 and headquartered in Osaka. The company operates two interconnected products: けんさぽ (Kensapo), an enterprise health management SaaS priced at ¥100/employee/month that bundles system access with operational outsourcing (health checkup booking, data entry, industrial physician coordination, stress check administration); and ログシル (Logsiru), the underlying consumer-facing PHR platform app that connects enterprises, medical institutions, pharmacies, and individuals for health information management, visualization, and selective data sharing.

The technical foundation is a cloud-based PHR platform with role-specific dashboards (employee, corporate HR, occupational health physician), selective health-data sharing, telemedicine consultation, vaccine and COVID-19 management, and wearable/testing-kit API integrations. A proprietary algorithm under in-house development analyzes accumulated vital data (blood pressure, heart rate, examination results) to produce AI-generated health scoring and personalized prevention/treatment recommendations, branded as a 'personal AI doctor'.

The business model is primarily per-seat subscription (¥100/employee/month base, with optional add-ons at similar pricing such as Central Sports' CS Live@HOME), supplemented by OEM/white-label development fees, API partnership revenue, and enterprise customization services. Distribution combines direct B2B sales to enterprise HR/management, self-serve app downloads via App Store and Google Play, OEM/white-label deployments, and a channel partnership with Central Sports reaching 370 nationwide fitness facilities. The company serves over 1,400 enterprise customers and has raised approximately ¥800M (~$5.3M USD) cumulatively across a July 2023 seed round, a July 2025 NTT Docomo Ventures strategic investment, and an October 2025 Series A.

Direct peers

• JMDC Inc. (Pep Up): JMDC operates Pep Up, a directly comparable employee-facing PHR/health management platform in Japan. Both serve enterprise customers with health checkup data management, vital tracking, and incentive-driven engagement - the most direct functional and buyer overlap in the Japanese market.
• Wellness Communications Co., Ltd. Specialist in corporate health management platforms for Japanese enterprises, including stress check systems and health checkup management. Closely comparable scope and target buyer to Kensapo/Logsiru.
• E-Well Corporation: Japanese corporate health management cloud platform focused on stress check programs and industrial physician coordination. Direct overlap on enterprise health management SaaS for the same industrial-physician-driven buyer.
• Centenarian (Kenko.com / KENKO & CO.): Japanese online health platform providing health management, supplements, and corporate wellness services. Overlaps with Personal Health Tech on consumer/enterprise health content and management distribution channels.

Broad incumbents

• Benefit One (Benefit One Inc.): A larger employee-benefits and welfare administration platform with corporate health management and EAP capabilities. Overlaps with Personal Health Tech on the enterprise welfare/health management buyer but with a much broader benefits portfolio.
• DeNA Co., Ltd. (Healthcare Division): Operates healthcare MyDNS and consumer health apps in Japan. Larger, publicly listed company with overlapping enterprise and consumer PHR functionality, providing a competitor with significantly greater capital and data resources.
• M3, Inc. Large digital health platform operating medical portals and healthcare professional networks. Broader Japanese digital-health incumbent with adjacent enterprise and physician-oriented capabilities that could expand into PHR/health management.

Emerging players

• SmartHR, Inc. Dominant Japanese HR/cloud SaaS platform that serves the same enterprise HR/management buyer and co-exhibits with Personal Health Tech at trade events. Indirect overlap today, but a credible platform-extension threat into health management features.
• freee K.K. Major Japanese SaaS provider in HR/finance cloud that addresses the same SMB/mid-market enterprise buyer wallet. Reasonable platform-extension threat into employee-benefits and health management adjacencies.

Others

• NTT Docomo (Healthcare Services): Strategic investor and distribution partner rather than a direct competitor. NTT Docomo's healthcare initiatives (dHealthcare, etc.) and its enterprise/consumer channel represent both a partnership vector and an adjacent strategic risk if NTT chose to deepen internal capabilities.
