Culture and etiquette: what to do, and what to say
Bow from the waist with a straight back. Foreign visitors are not expected to be precise; a small bow with a greeting is always welcome.
Short answer: Japanese etiquette and language are tied together: each gesture comes with set words. A bow goes with よろしくお願いします, entering a home with お邪魔します, handing over a gift with つまらないものですが. Underneath is the idea of 空気を読む, “reading the air”: noticing what others feel without being told, which is why so much in Japanese is said indirectly.
Visiting a home
Each step has its phrase.
Gifts and souvenirs
Give and receive with both hands. お土産 (souvenirs, usually food from your trip) are expected after travel, for colleagues as well as friends.

Chopsticks and the table
Two chopstick habits are linked to funerals, which is why they are avoided at meals.
Hot springs and public baths
Wash and rinse fully at the showers before entering the shared bath, keep towels out of the water, and check the sign for tattoos, which some baths still refuse.
Manners on trains
Public transport has quiet rules everyone follows.
Seasonal gifts
Two gift seasons, お中元 in summer and お歳暮 in winter, thank people for their help through the year.
