Japan Get adequate insurance, both travel and medical - medical treatment can be very expensive in Japan.       Check the Foreign and Commonwealth Office Travel Advice before travelling.       Don’t carry drugs or parcels or packages for 'friends'. Penalties are severe.       Bring enough money for the duration of your stay.       Keep belongings, especially your passport, safe.       Enter next of kin details into the back of your passport.       Don’t break the law - detention for minor offences can result in considerably longer stays in local police stations than is the case in the UK.       Obtain a proper visa if you intend working in Japan.       Don’t assume you can use you UK-credit or debit card to obtain cash from Automatic Cash Dispensers - many machines will not accept them and do not operate 24 hours a day, closing at   9pm or earlier.       If resident in Japan or staying for more than 3 months, register with the Consular Section in Tokyo (for those in Eastern Japan) or the British Consulate-General in Osaka (for those in Western Japan).       Don’t bring Vicks Inhalers purchased outside of Japan into the country (Vicks Inhalers contain a substance, 1-desoxyephedrine, which is banned for use or possession under Japan's strictly enforced Anti Stimulant Drugs Law).       Keep some cash for the departure tax if you are departing Japan from Kansai International Airport.       Western Union Money Transfer does not have any facilities in Japan.
