Understanding Japanese Business Customs
Japan has some of the most rigid and time-honored customs in the world. If you are not able to understand these customs and respect them, business travel to Japan could be just a waste of airfare.
However, if you don't have time to master every detail before you travel, don't worry: most business contacts won't expect a non-Japanese native to understand the intricacies of their culture. The key is always treating everyone, particularly those older than you, with respect. If you are respectful, then you can be restrained in your mannerisms until you start getting a feel for what makes your business partners comfortable.
A very respectful version of traditional Western etiquette is your best fallback plan if you're ever unsure how to behave.
What Not To Do
Above all else, avoid an overly enthusiastic imitation of Japanese culture while you travel the country. Don't try to imitate traditional Japanese customs exactly -- always let your business contact set the tone. Remember, he or she knows that you are coming from outside Japan, and is unlikely to expect that you will understand the intricacies of Japanese traditions. In fact, he or she may even try to cater to more Western etiquette, or may even do so naturally. Imagine how embarrassing it would be if you were to try aping Japanese culture only to discover that your new contact prefers more Western-style customs!
Polite And Impressive In Japan
The best rule to follow in Japan is to do as you see others doing. If you step into a building and see that there is a shoe cubby and slippers available, you will need to take off your shoes and put on the slippers. Continue observing how your hosts behave as you move further into the building. If your hosts prefer to bow from the hip and greet people with honorific titles, you will be well advised to do the same.
When meeting your business partner for the first time, it is equally appropriate to give a Western greeting or to give a bow from the waist. When bowing, keep your arms straight at your sides. Be careful not to over bow -- different depth bows indicate different things, and the meaning is all but impossible to learn without years of study.
The best way to bow correctly is by watching how others bow toward you, or how others bow to the contact before you. In addition, don't be afraid to start bowing after arrival. Your business contacts will only be impressed if you show adaptability by learning traditional customs.
