Those who dress according to their status or position impress the Japanese.
Casual dress is never appropriate in a business setting.
Shoes should be easy to remove, as you will do so often. Slip-ons are the best choice.
Women's dress should be conservative. Little emphasis should be placed on accessories. They should be minimal.
Women should only wear low-heeled shoes to avoid towering over men.
A kimono should be wrapped left over right to do otherwise symbolizes death.
Avoid using large hand gestures, unusual facial expressions and any dramatic movements. The Japanese do not talk with their hands and to do so could distract your host.
Avoid the "OK" sign; in Japan it means money.
Pointing in not acceptable.
Do no blow your nose in public
Personal space is valued. Because the Japanese live in such a densely populated area, they value their personal space.
A smile can have double meaning. It can express either joy or displeasure. Use caution with your facial expressions. They can be easily misunderstood.
The Japanese are not uncomfortable with silence. They use it to their advantage in many situations. Allow your host to sit in silence.
Behavior
The word for toasting is kampai, pronounced 'kahm-pie'. When toasting the glass is never left unfilled. Drinking is an important part of Japanese culture.
Never pour a drink yourself; always allow someone else to do it for you.
If you are invited to a social event, punctuality is not expected. It is the custom to be "fashionably late."
If you do take your host out insist upon paying. The Japanese will refuse but insist. They will prefer that you choose a Western-style restaurant when entertain them.
Key phrases to learn are "itadakimasu" at the beginning of dinner, and "gochisou-sama-deshita" at the end. It is polite use these phrase and it will show you host that you have enjoyed the meal.
"Sumimasen" (excuse-me) is a very useful term to add to your vocabulary along with the phrase "kekko desu" (I've had enough).
It is perfectly acceptable to slurp your noodles. Doing so will exhibit your enjoyment of your food. To do otherwise, indicates that your meal was not a pleasant one.
Do not openly display money. It is rare to see it given from person to person in Japan. It is important to use an envelope to pass money.
In Asia the number 14 is bad luck, because in Japanese it sounds like the word 'shuh-shuh', which sounds like the word for death.
Tipping is not expected.
Gift giving is very important both business and personal gifts
Style is tantamount. The gift itself is of little importance, the ceremony surrounding it is very important.
Always wrap gifts. The selection of the wrapping paper is critical. Do not give anything wrapped in white as it symbolizes death. Do not use bright colors or bows to wrap the gift. It is better to have the hotel or the store wrap the gift to ensure that it is appropriate.
Give the gift with both hands and accept gifts with hands.
Generally, gifts will not be opened in your presence. If your host insist that you open the gift do so gingerly. They take pride in gift wrapping, show that you appreciation the effort.
Do not give gifts in odd number or the number four, as odd numbers are bad luck and four sounds like the word for death in Japanese.
Gifts should be given at the end of a visit.
Do not admire anything belonging to your host too closely. The Japanese strive to please; you may be rewarded for your admiration.
Good gift ideas include top choice beef, fruit and alcohol such as brandy, quality whiskey and Bourbon along with excellent wines. They also appreciate gifts from high-end department stores like Saks and Neiman Marcus.
The Japanese frown on open displays of affection. They do not touch in public. It is highly inappropriate to touch someone of the opposite sex in public.
Communications
In Japan, business cards are called meishi. Japanese give and receive meishi with both hands. It should be printed in your home language on one side and Japanese on the other. Present the card with the Japanese language side up.
The customary greeting is the bow. However, some Japanese may greet you with a handshake, albeit a weak one. Do not misinterpret a weak handshake as an indication of character.
If you are greeted with a bow, return with a bow as low as the one you received. How low you bow determines the status of the relationship between you and the other individual. When you bow keep your eyes low and your palms flat next to your thighs. This is very important to remember.
In introductions use the person's last name plus the word san which means Mr. or Ms. The Japanese prefer to use last names. Do not request that they call you by your first name only. If you are uncertain about the pronunciation of a name, ask for assistance.
Understand that the Japanese prefer not to use the word no. If you ask a question they may simply respond with a yes but clearly mean no. Understanding this is critical in the negotiation process.
