Lie Your Ass Off
You will be asked many many times how old you are, if you have a significant other, where you're from--and in extreme examples--if you can use chopsticks. They'll also compliment your Japanese ability even if you have none. Any foreigner who has lived here for a time knows the questions and protocol of which I speak. Refuse outright to answer these questions, or better yet, lie your ass off. It will add greatly to the mystery surrounding you, and drive them freakin' crazy in a good way. Japanese love comic book fantasy. Fulfill that for them.
Eat Lunch Alone
If you're a non-smoker, then you'd better eat lunch alone. If your coworkers are mostly Japanese guys, and you eat with them; you're officially a chain smoker. If they persist, then take them to a non-smoking restaurant (good luck finding one). You'll never be asked to lunch again. If you're a smoker, then eat lunch with your Japanese coworkers everyday. Free cigs!
Ask a Woman
If you have a question or need help, ask a Japanese woman. She does all the work and knows absolutely everything. Don't waste your time with the dudes (esp. the older ones). They won't have a clue and will inevitably refer you to the hardworking, underpaid, under-appreciated Japanese woman. The entire weight of the company rests on her shoulders. If you're a woman, then welcome to Japan!
Leave On Time
Leave on time from day one. This is very important, and you have to set this up from the outset. For me this is at 6:00pm and 00 seconds exactly. All of your Japanese coworkers will look at you strangely--as if you're dressed like a rodeo clown. Resist the pressure to sit back down and work until 10:00pm everyday like they do. Work to live, don't live to work.
The Japanese company will try to make you feel like they are your new family and they come first. This is their culture--not mine, I say. This is a job, and that's all it is. Personally, my real family and friends (Japanese included) are a lot more fun to be with, and I structure my schedule accordingly. I'm cautiously optimistic and hoping my leaving-on-time ethic will rub off on my Japanese coworkers; but realistically I'm probably dreaming. So far they just give me dirty looks; and needless to say, I haven't made any friends.
Take Acting Lessons
Japanese are terrible actors on TV, but Oscar award-winning in the office. I stand dumbfounded at how some coworkers can do absolutely nothing all day, yet appear busier than NYSE trader soccer moms attending medical school in the evenings. As such skills are invaluable in life, I advise studying this. Observe them closely and watch how they pretend to work. Mimic their movements and eccentricities. Sign up for acting lessons after work (or during work) with an emphasis on "the workplace." Mad drama skills like these will take you very far.
Be Aloof and Weird
Nice guys finish last, and this is 200% true at a Japanese company. Research has found that women in general are nicer than guys, and this is why Japanese women end up doing all the work. Nobody likes work, so do everything in your power to avoid it. The ideal working equation should be pretending to work, while avoiding real work and collecting an undeserved paycheck. Nothing accomplishes this better than being aloof, weird, and a bit of an asshole.
Since they consider you family, Japanese managers do everything they can to avoid confrontation (something about harmony or whatever). So playing the part of the abused autistic middle child will endow you with sympathy, tolerance, and a whole lot of free time. When you sense the tolerance threshold wavering into the red, then play the reverse discrimination angle and dismiss their frustrations with "It's because I'm a foreigner!" This will remind them that you're not Japanese and thus have "special needs." In time they will learn to be proud of their backward, retarded child, and you will enjoy a relaxing, stress-free workweek devoid of work.
So dear fellow foreigner--I wish you the best of luck at your Japanese company and pray these tips prove advantageous. Now, get back to work...just kidding!
Wait...is that his hand down- what?!? Oh, shit. This is real life. Being half asleep coming back from an exhausting job in Shibuya and on my way to a photoshoot...
