Japan offers something for everyone all year round. Stunning scenery and cherry blossoms in Spring, snow activities in Winter and great cuisine 12 months of the year. You can even climb a mountain to demonstrate your level of fitness.

Many Australians work in Japan and use it as a base for more extensive travel. This must be considered when preparing an expatriate worker.

Health advice for Japan will vary depending on your reason for travel (holiday, work, volunteering, visiting friends or relatives), your accommodation (hotel, homestay or long term rental), length of stay, and time of year (eg typhoon season or winter flu season). Urban settings like Tokyo or Osaka may pose different considerations compared to rural areas or mountainous regions. Your current health status may also influence your travel plans. 

Japan has health concerns similar to Australia. However, travellers may face a greater risk of exposure to respiratory tract infections, particularly due to time spent in crowded spaces such as airports, bullet trains, subways and busy tourist attractions.

Travel Considerations

Japan  FAQs

Japanese encephalitis is a notifiable disease in Japan and very few cases are reported annually.

Just 55 cases were notified for the period 2007-2016. Most cases were reported between August and September (monsoon months) with the earliest in April and latest in November. Most cases came from the western regions.

For most travellers to Japan, the risk of Japanese Encephalitis is very low. JE vaccination might be considered for those planning to live in Japan for extended periods. It might also be considered for those undertaking rural travel in areas of risk during the monsoon months.

Risk of exposure can be influenced by outdoor activities and the type of accommodation.

If you are planning to spend a short period of time in a major urban area (Tokyo, Osaka, Kyoto etc) vaccination is less likely to be recommended.

Japan has always been prone to earthquakes. They can occur at any time and almost anywhere. There is at least 1 felt per day by many people somewhere in Japan.

Over 200 people died in the most recent one in early 2024 in western Japan.

Those causing the most damage – mega earthquakes – are fortunately rare (one in a hundred years event). Modern buildings are built to withstand most earthquakes and procedures are in place should a quake occur. Always read what information is available during your stay. In the event of a quake, follow advice.

Natural disasters come in many forms. Australia has its cyclones and bushfires.
