Other social tips
Respect
The suffix "san" is often used when you refer to someone else and is a term of respect. If referring to Mr/Mrs Suzuki, you would say, "Suzuki-san". However, you would never refer to yourself as "-san" and would only use your name on its own.
Eating
Before eating a meal, the Japanese put their hands together and use the term "Itadakimasu" (I humbly receive). After the meal, it is polite to say "Gochiso sama deshita" (thank you for the meal).
Japanese people will understand if visitors do not have proficient use of chopsticks, but there are some rules you should try and follow:
Do not stick your chopsticks into your bowl of rice or pass food around with them. As well as being slightly uncouth, these actions have relevance to the Japanese funeral ceremony.
It is also advisable not to douse your rice in soy sauce. The Japanese are very proud of their rice and this seemingly innocent action may surprise and even offend some ryokan/restaurant owners.
It is not common practice to walk and eat in public and is considered bad manners. You may sit down in a public place and eat or stand at tachi-gui restaurant/shops, but walking and eating is not polite.
Tipping
There is no tipping in Japanese restaurants or other places that many westerners will expect to tip. The Japanese will always give the best service they can and do their jobs proudly. A waiter or chef would certainly not accept a tip for doing their jobs and if you tried to leave one, they would awkwardly return your money, so don't tip
