Health & safety
No vaccinations are required for Japan. Your routine vaccinations should be up to date, though travellers at special risk should additionally consider the following:
Japanese B encephalitis There is no risk in Tokyo, but there is risk in rural areas of all islands. The risk is highest in the western part of the country from July to October.
Tick-borne encephalitis This is present only in the wooded areas of Hokkaidō and is transmitted between April and October. The vaccine is readily available in Europe but can be difficult to find elsewhere.
