When on a train it is usually customary to respect peoples space where possible. This includes usage of mobile phones in trains. It is generally considered rude to be talking on a phone in a train, for those who do need to take calls the etiquette is to keep the conversation to a minimum and suggest you call back later or not take the call at all and message why you cannot talk. It is also polite to keep the phone volume down so as not to disturb other passengers.
In Japan, people greet each other by bowing. The bow will range from a small nod of the head (casual / informal) to a deep bend at the waist (indication of respect) in more formal situations. For tourists to Japan a bow of the head is usually sufficient as most Japanese people don’t expect foreigners to know Japanese rules on how to bow appropriately. Shaking hands in Japan is uncommon so a bow is often preferred.
INDOOR – RYOKANS ETC
There are rules regarding indoor manners and an important one to remember is regarding footwear. Shoes are removed in homes, some hotels and most traditional ryokans (Japanese style accommodation), some restaurants, temples, castles and other historic buildings. There is usually an entrance area which is called “genkan”, and shoes should be always pointed towards the door rather than into the building.
The Shinto religion is as old as the Japanese culture, while Buddhism was imported from overseas in the 6th century. Both religions have co-existed in relative harmony and Japanese tend to observe both. Some holidays in Japan are following the Buddhist traditions and others follow Shintoism. Religion does not play a big role in the everyday life of many Japanese and is more customary than a strong belief. A person will follow the rituals during a wedding, birth or death and when they visit a shrine or temple but many are not strong in their beliefs. At New Year and during festivals (matsuri), most of which have a religious background, Japanese will adhere to the religious protocol.
