It’s a good idea to take a little time to understand the culture of the Asian countries you are visiting. Generally speaking, extreme politeness is important, as is taking the time to greet people, and remaining softly spoken.
Many Asian countries are Buddhist, in which case, always show respect to Buddha statues and temples and do not touch Buddhist monks. Do not point at people and do not be surprised if a local avoids eye contact during a conversation; this is a sign of respect. In Thailand, it is an offense to say anything negative about the royal family.
Try to understand the sense of “face” that is prevalent in Asian countries. Saving face is important; so, for example, a person may tell you what they think you want to hear rather than the reality, to avoid losing face. Shouting at someone causes you to lose face.
Japan in particular is a country with a complex social etiquette. Just a few include not tipping (it’s just not done here); never blowing your nose in public; taking off your shoes before entering a temple; and not blocking busy sidewalks in the densely populated cities.
If you’re visiting somewhere on a tour where specific etiquette is expected, your guide will point out all you need to know.
