No vaccination certificates are required for entry to Japan.
There have been recent outbreaks of the deadly bird flu, but no
human infections have been reported. Travellers to Japan are
unlikely to be affected, but live animal markets and places where
contact with live poultry is possible should be avoided, and all
poultry and egg dishes well cooked. Medical facilities are very
good, but medical assistance in Japan can be very expensive and
visitors have to pay the whole cost up front. Travellers should
ensure that they have adequate medical insurance before travelling.
The possession of Vicks inhalers and other common medications used
for allergies and sinus problems are banned under the strictly
enforced anti-stimulant drugs law, and visitors are advised to
check with the Japanese embassy if in doubt.
