It is only necessary to follow the standard rules of conduct in public places. Everything else is nuances.

Yes, of course, as in any other country. In Japan, the basis of etiquette is courtesy and restraint in behavior.

Also, it is customary to greet each other with obeisances. In Japan, there is no tradition to use a handshake during a greeting. This is considered an intrusion into a person's personal space, so do not stretch the palm of your hand for the handshake first. If the Japanese himself wishes to greet you with this "European" way, he will first extend his hand.

In Japan, there are a lot of different rules and regulations, unusual for Europeans and Russians, but local residents are rather loyal, making a discount for foreigners, but do not forget that it behaves politely, and respect the culture of the country not only in Japan, but in any other country.
