Company profile
researched Aug 2026FastDOCTOR Inc. (ファストドクター株式会社) operates the "FastDoctor" medical platform in Japan, combining online (video) consultations with emergency house-call visits to patients' homes. Services run year-round, including nights, weekends and the year-end/New Year period, and are delivered through medical institutions that participate in the FastDoctor network rather than by the company itself; the company runs the underlying system and operations.
Online consultation covers internal medicine and pediatrics, dermatology, allergy/hay fever, gastroenterology, respiratory medicine, urology, lifestyle-disease outpatient care, psychosomatic medicine/psychiatry, child psychiatry and counselling, with prescriptions issued at the physician's discretion for conditions such as influenza, COVID-19, streptococcal and adenovirus infections, cold symptoms, allergies, headache, gastrointestinal and respiratory symptoms, rashes, otitis media and cystitis. Emergency house calls, restricted to cases the company deems urgent, allow on-site testing (influenza, COVID-19, strep tests, vital signs, otoscopy), procedures such as suturing, drips and fixation of injured areas, and direct handover of medication; some internal-medicine and orthopedic house-call categories are available only in parts of Tokyo. Health insurance cards and medical certificates are accepted, and consultations can be requested through a dedicated app.
Alongside the consumer service, the company runs business lines aimed at institutions: an after-hours house-call cooperation service for home-care medical providers, 24-hour medical support offerings for local governments, a corporate/BtoB division, and newer units covering acute-phase online care, mental health clinics and online lifestyle-disease care. Product and engineering work sits under FastDOCTOR Technologies.
Founding story
Ryo Kikuchi graduated from Teikyo University School of Medicine in 2010 and worked in orthopedic surgery at Teikyo University Hospital and affiliated hospitals before founding FastDOCTOR in 2016 and becoming representative director. He co-founded the company with Yuji Koishi, who had previously worked in new business units at Opt and Macromill before going independent in 2013.
Business model
The company operates a medical platform: patients request online consultations or emergency house calls, and care is provided by participating partner medical institutions, with FastDOCTOR running the system, operations, logistics, physician coordination and quality management. Care is delivered under Japanese health insurance, with certain services (e.g. medical counselling) outside insurance coverage. Additional lines serve home-care medical institutions (after-hours house-call cooperation), local governments (24-hour medical support) and corporate clients.
Consultations and house calls are provided as insured medical care, with health insurance cards and medical certificates accepted; some services such as medical counselling are stated to be outside insurance coverage. The company also offers contracted services to home-care medical institutions, local governments and corporate clients.
Traction
The platform reported 2.52 million cumulative uses as of the end of March 2026, and the company listed 210 employees as of November 2023, with roughly half of staff engaged in business or product planning and development.
Latest developments
The company continues to expand its partner medical institution network nationwide with the stated aim of enabling online consultations without reimbursement procedures, and has added newer business lines in acute-phase online care, mental health and online lifestyle-disease care. Platform usage reached 2.52 million cases as of the end of March 2026.
