Japan’s medical system, predicated on universal health insurance, is one of the world’s best systems for receiving high-quality medical care at a low cost. However, the methods of accessing medical facilities and the rules for consultations have evolved in a uniquely “Galapagos” way, creating a highly complex infrastructure for newly arrived foreigners.
Bringing your home country’s common sense—such as “going directly to a big hospital for a cold” or “booking easily online and paying cashless”—carries the risk of being charged unexpected extra fees or being refused consultation entirely. This article logically outlines the objective practical procedures foreigners must follow to utilize Japan’s medical infrastructure correctly.
1. The Division of Roles Between Hospitals and Clinics (The Referral Wall)
[Summary] Going directly to a large hospital for a cold or minor injury will result in thousands of yen in extra penalty fees. The absolute rule in Japan is to first visit a small, local “Clinic.”
Japan’s medical infrastructure is clearly divided into “Clinics” (small medical offices) that treat everyday illnesses, and “General Hospitals” (large hospitals) that perform advanced tests and surgeries.
When foreigners fall ill, they often tend to go directly to well-equipped large hospitals, but this is a major practical mistake. Large Japanese hospitals operate basically on a “referral system.” If you visit a large hospital directly without a “Referral Letter” (Shokaijo) issued by a clinic doctor, you will be penalized with a special “Sentei Ryoyohi” (Selective Medical Care Fee) of about 7,000 to 10,000 JPY on top of normal medical expenses. When feeling unwell, strictly follow the procedure of visiting a nearby specialized clinic (such as internal medicine or ENT) first.
2. Outdated Reservation Systems and the First-Visit Hurdle
[Summary] Many facilities mandate “phone reservations only for first visits” or “no reservations (walk in and wait).” Even when online booking is available, registration on a proprietary app is often required.
The reservation systems of Japanese clinics are not unified; the rules vary completely from facility to facility.
For a patient’s very first visit (Shoshin), many clinics require you to either “walk in directly and wait your turn” or “make an advance reservation by phone.” Facilities equipped with English-friendly online booking systems are in the minority. If you walk in without a reservation, waiting for 1 to 2 hours is the norm. If making a phone reservation in Japanese is difficult immediately after relocation, the objective approach is to ask for interpreter support or request your company’s HR to make the initial phone call.
3. Strict Etiquette at the Reception and Waiting Room
[Summary] Presenting your “Health Insurance Card” at reception is an absolute requirement. Furthermore, phone calls are prohibited in the waiting room, and many facilities require you to take off your outdoor shoes.
The code of conduct upon arriving at the clinic also involves strict rules unique to Japan.
- Presenting the Health Insurance Card: You are legally required to present your “Health Insurance Card” (Hokensho) at your first visit and on your first visit of every subsequent month. Forgetting it means you must pay the full 100% of the medical costs out-of-pocket that day.
- No Outdoor Shoes Rule: Many small clinics and dental offices still enforce a strict “no outdoor shoes” rule, requiring you to take off your shoes at the entrance and change into slippers provided by the facility.
- Waiting Room Silence: Making or taking phone calls in the waiting room is strictly prohibited. The objective etiquette is to put your phone on silent mode (Manner Mode) and wait quietly for your name to be called.
4. Practical Q&A (Payment Methods and Medical Questionnaires)
[Summary] “Cash Only” clinics are still the majority. Also, you must fill out a “Medical Questionnaire” (Monshinhyo) in Japanese before the consultation, making advance translation preparation essential.
Q. Can I use a credit card to pay my medical bills?
A. While large general hospitals accept credit cards, privately run clinics (local doctors) that are “Cash Only” still form the overwhelming majority. As a practical defensive measure, always ensure you have several thousand to ten thousand JPY in cash in your wallet before visiting a clinic.
Q. If I explain my symptoms in English, will they understand?
A. At your first visit, you will always be required to fill out a paper document called a “Medical Questionnaire” (Monshinhyo), detailing your current symptoms, allergies, and medical history. Since this form is often only in Japanese, relying on a translation app after receiving it at the reception will waste a massive amount of time. By taking the objective step of noting down your symptoms and allergy information in Japanese beforehand (on paper or your smartphone) and presenting it to the receptionist, you can eliminate the risk of misdiagnosis caused by language barriers.
Conclusion: Secure Your “Family Doctor” Infrastructure While Healthy
If foreigners scramble to find a hospital only after falling ill, they will be blocked by the walls of reservation systems and language, leading to a situation where they cannot access appropriate medical care. To build a safe life foundation in Japan, it is essential to execute a roadmap: while you are still healthy, research “clinics with English support” or “hospitals that accept credit cards” near your home or workplace, and secure them as your practical medical infrastructure.
