What Call Doctor does
Call Doctor (legal entity: 株式会社コールドクター, DBA: みてねコールドクター) is a Japanese telemedicine operator headquartered in Shibuya, Tokyo. Founded in October 2020, the company runs a mobile-first (iOS/Android) online medical consultation platform that connects patients with physicians for 24/7 video consultations covering internal medicine, pediatrics, dermatology, allergies, and infectious diseases. The service is integrated with Japan's national health insurance system — adult patients pay ¥1,240–¥2,430 per consultation depending on time of day (30% co-pay), while children covered by municipal medical financial assistance programs (e.g., Tokyo 23 wards up to age 18) pay ¥0 — and prescriptions issued during consultations can be picked up same-day at nearby partner pharmacies. The company also offers self-pay (保険適用外) services including aesthetic medicine, low-dose oral contraceptives, and AGA treatment, and maintains a nationwide hospital/clinic search directory covering all 47 prefectures of Japan.
The underlying technology is a consumer-grade mobile telemedicine stack — iOS and Android apps distributed via the App Store and Google Play, with QR-code-driven web-to-app conversion, in-app video consultation, prescription routing, and digital issuance of medical certificates and school absence permits. Payments are processed via GMO Payment Gateway (credit card and GMO post-pay) and atone (deferred payment for self-pay services). Marketing uses a multi-channel mix including paid acquisition on Google, Meta, LINE, Yahoo Japan, Twitter/X, TikTok, and Smartnews, alongside organic content (medical articles, user testimonials) and social accounts on Instagram and X. A home-visit (往診) service was previously offered but has been discontinued, with focus now concentrated on the online consultation platform.
The business model is transactional: patients pay ¥0 in system usage fees, and Call Doctor collects per-consultation fees from partner medical institutions whose doctors deliver the consultations on the platform. Primary customer segments are families with children (pediatric acute care, especially nights/weekends/holidays) and working adults with acute symptoms; a secondary segment is chronic disease patients. The company is privately held, founder/management-owned, with no parent company disclosed, and has raised approximately $1.93M in a single disclosed seed/early round (December 2020) from CyberAgent and XTech Ventures.

Revenue model
- Per-Consultation Fees (Insurance-Covered): Patients pay a consultation fee per session under Japan's national health insurance system. For adults the fee ranges from ¥1,240–¥2,430 depending on time of day (weekday/daytime lower, night/late-night higher). For children covered by municipal medical assistance programs (e.g., Tokyo 23-ku up to age 18), the patient cost is ¥0. Call Doctor collects a platform fee from partner medical institutions.
- Per-Consultation Fees (Self-Pay / Free Medical): For uninsured services such as beauty treatments, low-dose oral contraceptives, and AGA (hair loss treatment), patients pay out-of-pocket at a per-consultation rate.
- Platform / System Usage Fee (¥0 to user): The service explicitly states that system usage fees are ¥0 for patients. Revenue is derived from per-consultation fees collected from partner medical institutions rather than directly from consumers.

Call Doctor competitors and assessment
Company assessmentBroad incumbents
- Teladoc Health: Global leader in virtual care offering 24/7 video consultations, chronic condition management, and integrated pharmacy. Comparable on the underlying telehealth business model Call Doctor operates, though at vastly greater scale and breadth.
- Amwell: US-based telehealth platform serving payers, providers, and patients with on-demand and scheduled virtual care. Comparable as a broader incumbent offering insurance-integrated virtual urgent care and primary care at national scale.
- M3 (m3.com): Large Japanese medical internet company operating m3.com physician portal and adjacent telehealth/online consultation services. Comparable as a broad incumbent in Japanese digital health with overlapping physician supply and consultation capabilities.
Emerging players
- Practo: India-based digital healthcare platform offering online consultations, prescription delivery, and clinic discovery. Comparable as a mobile-first, multi-specialty telehealth platform combining consultations with a healthcare provider directory.
- Doctor Anywhere: Asia-Pacific telehealth platform offering video consultations, prescriptions, and chronic care across Southeast Asia. Comparable on the mobile-first, insurance- and self-pay-blended telehealth model targeting acute and family health use cases.
- Kids Public: Japanese digital health startup operating pediatric-specialized online consultation services (e.g., '小児科オンライン'). Closely comparable on the pediatric telehealth niche Call Doctor emphasizes, with overlap in parent-facing acute care use cases.
- Halodoc: Indonesia-based telehealth and pharmacy-delivery platform. Comparable as an app-first online consultation and prescription-pickup platform in an Asian market with similar regulatory and consumer dynamics.
Direct peers
- LINE Healthcare (LINE Doctor): LINE's telehealth platform offering online consultations via the LINE app in Japan. Directly competes on the same D2C telehealth channel, leveraging LINE's massive Japanese user base for distribution — a key competitive risk to Call Doctor's mobile-app growth strategy.
- Medley (CLINICS): Japanese digital health company operating CLINICS, one of the leading online consultation platforms in Japan. Directly comparable on insurance-covered video consultations, prescription delivery, and a broad specialty footprint serving both pediatric and adult patients.
Others
- Novartis (telehealth-adjacent pharma): While not a direct telehealth operator, Novartis and similar pharma players are ecosystem participants integrating with platforms like Call Doctor via prescription fulfillment and chronic disease programs. Useful as an adjacent reference for pharmacy-integrated telehealth models.
