What Mediplat does

Mediplat (株式会社Mediplat) is a Tokyo-based, privately held Japanese company founded on November 25, 2015, and operating as a wholly-owned subsidiary of Advance Risk Management Co., Ltd. (株式会社アドバンテッジリスクマネジメント). The company operates "first call" (ファーストコール), a cloud-based occupational health management platform that consolidates the legally and operationally fragmented set of corporate health obligations faced by Japanese employers—occupational physician placement, workplace inspections, stress checks, health examination recordkeeping, and 24/7 employee medical consultations—into a single web and mobile application.

The platform is delivered as a subscription SaaS product with tiered pricing based on registered employee headcount for the health examination management module (¥15,000 to ¥100,000 per month across seven tiers from 1 to 5,000+ employees), annual contracts for occupational physician placement, and a transactional spot consultation option at ¥25,000 per 30-minute session. Technical components include an online industrial physician interview scheduling system with calendar synchronization, OCR-based digitization of paper health examination results, and SSO integration via NTT Docomo's d account. The platform is ISO 27001 certified (IS 737837, February 2021). Underlying medical interactions rely on registered human physicians (covering 12 specialties) rather than autonomous AI, with chat-based and video-based delivery channels plus 24/7 anonymous employee access.

The go-to-market combines direct enterprise field sales targeting HR/labor management at companies with 50+ employees (the threshold triggering mandatory occupational physician appointment under Japan's Industrial Safety and Health Act) with a channel partner program covering social insurance labor consultants, accounting firms, banks, insurance companies, and consulting firms. Pricing tiers and customer evidence span SMBs (e.g., Showa Gas, Yamanashi Yakult, Technos, Samepage), mid-market firms (Sold Out), and enterprise buyers (JAC Recruitment). As of August 2024, first call served 1,500+ contracted business sites nationwide, ranging from companies with fewer than 50 employees to those with over 10,000 employees.

Broad incumbents

• MedPeer, Inc. Tokyo-based platform that aggregates Japan's physician community for knowledge-sharing and clinical decision support, and operates AskDoctors for consumer Q&A. Comparable because it monetizes Japan-wide physician engagement and consumer health access, overlapping with Mediplat's nationwide doctor-network and online medical consultation surfaces.
• LINE Healthcare (LINE ヘルスケア): Consumer telehealth service operated by LY Corporation (LINE's parent) offering online medical consultations and asynchronous physician chat via the LINE messenger super-app used by most Japanese consumers. Comparable as a Japanese online consultation platform with broad consumer reach; overlaps with Mediplat's anonymous chat/TV consultation surface but lacks Mediplat's employer and occupational physician focus.
• M3 Inc. Tokyo-headquartered, publicly listed Japanese medical information and platform company operating m3.com and a broad suite of physician- and pharma-facing digital services, including corporate marketing tools and clinical trial platforms. Comparable as a Japanese digital health platform sitting between physicians, employers, and consumers, but with a much broader portfolio than Mediplat's focused occupational health stack.
• SOMPO Health Support / SOMPO Wellness: SOMPO group health-support entities providing corporate wellness, health guidance, mental health support, and stress check services to Japanese employers through insurance carrier and HR channels. Comparable as a well-capitalized Japanese incumbent bundling occupational and mental health services into corporate benefits programs, competing for the same employer wallet Mediplat pursues via direct sales and partner channels.
• DeNA Co., Ltd. (MySOS / Healthcare): Tokyo-headquartered Japanese internet company with a healthcare vertical that includes MySOS (emergency medical information and online consultation) and various digital health initiatives. Comparable because DeNA operates Japanese consumer health apps and online consultation infrastructure that intersect Mediplat's 24/7 anonymous chat consultation product and corporate distribution ambitions.

Emerging players

• Welby, Inc. Tokyo-based Japanese digital health company providing self-management apps and SaaS for chronic disease patients (diabetes, hypertension, oncology, lifestyle diseases). Comparable because it layers patient engagement, data capture, and physician-sharing on top of employer and pharma relationships, overlapping Mediplat's health-examination data, OCR ingest, and chronic-condition tracking surfaces.
• Asken, Inc. Tokyo-based Japanese health-tech company behind the calorie/meal-tracking app and corporate wellness programs built on nutrition and lifestyle data. Comparable because it sells subscription wellness services into Japanese employers and insurers, channeling behavioral and biometric data back into population-health dashboards analogous to Mediplat's stress check and health-exam modules.
• CureApp, Inc. Tokyo-based Japanese digital therapeutics company developing prescription digital therapeutics for conditions including nicotine dependence and hypertension. Comparable as a Japanese specialist digital health player selling clinically validated, condition-specific programs through health systems and employers, intersecting Mediplat's chronic-condition and corporate wellness footprint.

Direct peers

• Cority Software Inc. Toronto-based occupational health, safety, and environmental SaaS platform delivering industrial hygiene, medical surveillance, and employee health records to global enterprises. Highly comparable as a purpose-built cloud occupational health platform with clinical modules (including mental health and health surveillance) sold to employers with 50+ employees across multiple jurisdictions — the same wedge Mediplat targets with first call.
• Medgate AG: Swiss physician-led telemedicine and occupational health provider operating a global 24/7 multilingual medical contact center for employees of multinational employers. Directly comparable as a clinician-staffed virtual care platform whose occupational health, absenteeism management, and employer-paid consultation model mirror the corporate compliance and online consultation orientation of Mediplat's first call service.
