Japan - Local Customs
The Japanese are formal and reserved and visitors are expected to behave politely. Their system of etiquette is one of the most complex in the world, with a strict code of conduct for almost every situation. It is important to avoid causing 'loss of face' by insulting or criticizing someone in front of others. Bowing is the customary greeting. The possession of common prescription, or over the counter medicines, particularly for allergies and sinus problems, are forbidden under Japanese law, and it is highly advisable to check with a Japanese embassy before travel.
