Vaccines for Japan: What Travelers Need to Know

Do you need vaccines to enter Japan?

Recommended vaccines before traveling to Japan

Although Japan does not require vaccinations for entry, healthcare professionals generally recommend that travelers be up-to-date on their routine immunizations before visiting any international destination.

The following vaccines may be recommended depending on your age, medical history, and travel plans.

• Routine vaccinations: Ensure you are current on routine immunizations such as measles, mumps, rubella (MMR), tetanus, diphtheria, pertussis, polio, chickenpox (varicella), and seasonal influenza, according to your country's vaccination schedule.
• COVID-19: Although proof of vaccination is not required to enter Japan, staying up to date with recommended COVID-19 vaccinations may still provide additional protection while traveling.
• Hepatitis A: Some healthcare providers recommend this vaccine for travelers, particularly those planning longer stays or extensive travel throughout the country.
• Hepatitis B: This vaccine may be recommended for long-term visitors or travelers who could require medical treatment during their stay.
• Rabies: Most tourists do not need a rabies vaccination. However, it may be recommended for travelers spending extended periods in rural areas, working with animals, or participating in activities that increase exposure to wildlife.
• Japanese Encephalitis: This vaccine is generally recommended only for travelers spending significant time in rural or agricultural areas during mosquito season, particularly for trips lasting one month or longer.

If you are unsure which vaccines are appropriate for your trip, consult your healthcare provider or a travel medicine clinic before departure.

Is Japan safe regarding infectious diseases?

Japan is considered one of the safest destinations in Asia with regard to infectious diseases. The country maintains high public health standards, excellent sanitation, and a modern healthcare system, all of which contribute to a relatively low risk for most travelers.

Visitors can safely drink tap water throughout most of the country, and food hygiene standards are generally excellent. Restaurants, hotels, convenience stores, and public facilities maintain high levels of cleanliness, making food- and water-borne illnesses relatively uncommon.

Like any destination, seasonal illnesses still occur. Influenza circulates during the winter months, while occasional cases of measles or other vaccine-preventable diseases may be reported. Staying current with routine vaccinations remains the best way to reduce these risks.

During the warmer months, mosquitoes are present throughout much of Japan. While mosquito-borne diseases are uncommon for most visitors, using insect repellent and wearing appropriate clothing when hiking or spending time outdoors is always recommended.

Healthcare in Japan

Japan has one of the world's most advanced healthcare systems, with modern hospitals, well-equipped clinics, and highly trained medical professionals. Travelers can expect excellent standards of care throughout the country, particularly in larger cities.

English-speaking doctors and international medical clinics are widely available in destinations throughout the country, especially in major cities, although English services may be more limited in smaller towns and rural areas.

Pharmacies are also common throughout Japan, and many carry over-the-counter medications for minor illnesses such as headaches, allergies, colds, and stomach discomfort. However, some medications that are readily available in other countries may require a prescription in Japan or may not be sold at all.
