Working in a Japanese company can be vastly different from say working for an American company. Respect for elders, promotion by seniority and unconditional submission of subordinates are just some of the rules one have to comply with, if not...
Well, here are top 10 tips on how to survive working for/with the Japanese:
(1) No Opinions please: Don't ever voice out your opinion unless they are praises for the company. Remember, even when the boss asks you for suggestions on improvements, don't stupidly reveal them. This will only lead them to identify you as a potential problem.
(2) Always show that you are happy: Don't ever sulk, or come to work looking bored or tired. The Japanese expect their workers to look happy and full of energy every minute. Once, I had a female colleague who rested her elbows on the table, cupping her chin with her hands reading a report. The boss told her not to sit like that even when she was doing genuine work. Image counts.
(3) Don't be Punctual, BE EARLY: Japanese expect their staff to report to work at least 30 mins before the official start time. That means, you must be seated at your desk (remember don't rest your elbows), have drunk your morning coffee and be all ready to start work at least 15 mins before official start time. I once had a friend who came into work at 8:15 am when the official start time was 8:30am. The boss pulled her aside and told her to come in and be seated by 8am. No later. And it does'nt matter that there was'nt really much work to do until 10am because the boss himself came in at 6:30am everyday (God knows what he was doing)
(4) Don't Take Afternoon Naps, unless you are Japanese : Japanese culture has it that employees will usually take short naps at their desks after lunch. However, this is an entitlement only for the Japanese. If you are non-Japanese, you will get stares if you do the same (some of the Japanese will lie flat on their desks, looking like real gonners - to show that they have been working really hard). Oh, and if you are a woman, naps are absolute no-no.
(5) Lunch, 30 minutes at most: Even if you are entitled to 1-hour lunch break, your boss will probably tell you to come back 30 mins latest. Don't even bother telling him it is stated in your employment terms because he will then take underhand actions to make you return earlier for work reasons or something.
(6) Don't Eat/Drink at your desk: I know there are times when you just want to lunch-in. However, Japanese do not like their staff to eat at their desks because the food smell might permeate the office (this rule however will not apply to the boss who can bring in curry rice bento as often as he likes). Eat-in only if by doing so you can show that you are so hardworking that you are sacrificing your lunchbreak to do your work. If not, this a big no-no.
(7) Don't Talk Loudly: My ex-Japanese manager said he did not like to talk to Americans because they were loud, brash and intimidating. Japanese find it unacceptable when Americans come to them saying "hi, how are you" in their loud, friendly voices. So what might seem harmless and courteous on your part, actually peeves them. really.
( No Personal Calls/Emails: It doesn$B!G(Bt matter that your boss might be talking really loudly in Japanese on a very obvious personal call. You cannot do the same. Don't start laughing or chatting away even when it is with your clients. I once had a Chinese sales manager who was making work-related calls in Mandarin. The Japanese boss immediately assumed it was a personal call, just because the guy was laughing and chatting with the client. The boss obviously did not know it was the way to build relationships with Chinese clients.
(9) Do not speak in a Foreign Language with your peers: Speaking in a language besides English (maybe mother tongue languages) will cause unnecessary suspicion from your boss. A Japanese company once banned the usage of Mandarin and other dialects in a Southeast Asian office among the locals. However, the Japanese continued to speak in their own language among themselves.
(10) Don't EVER go home before your boss: This is probably the most famous rule for Japanese corporate. Even if it means just hanging around doing nothing, you must not leave before your boss. It's a sign of insubordination and disrespect.
Of course, some Japanese corporate have evolved to be more modern over time. However, traditional office culture like the ones above still exist. So before you join a Japanese corp, think twice and do ample research!
