Make an office plan
These are the people your going to work with for at least the next year, so wouldn't it be nice to know who they are?
Many doors will open faster if you can preface your questions with, "Sumimasen, [insert name]-sensei, how/ where/ when/ why do I . . .?"
For very simple things like the office plan, speaking English very slowly will usually work.
One technique to learn names is to draw a mud map of your office, and then ask each teacher to write his or her name in English and Japanese (Kanji and Hiragana) on it in the appropriate place.
This can also double as an icebreaker for introducing yourself, and might even be your first experience with meeting a new friend.
Remember that teachers are often busy, so pick the right moment before disturbing them, but other than that, go for it.
Introduce Yourself to as Many Teachers as Possible
Your first meeting with teachers will probably involve you standing up in the staff room and making a short speech about who you are and where you come from. Don't be worried about this. Nobody expects you to speak Japanese. Just speak English VERY slowly and VERY clearly. One thing you will learn about using English here is that many Japanese can speak a little, as most people did at least six years of it at school. If you speak slowly and clearly you will often be rewarded with nods of understanding (this can deceive you into believing that you're actually being understood, but I'll leave you to discover that on your own). And don't forget to say how happy you are to be here. It may well be a fiction, but it's a fiction that will ingratiate you to your co-workers.
So now that you're all introduced, that's all you have to do? Well, unless you want to spend your school hours sitting by yourself, you're going to have to get off your butt and start networking. Can't speak the language, well that doesn't matter. Later on you'll need to articulate your demands, but for now if you nod, smile, appear interested in what is going on, nod, then smile some more, you'll be pushing the barrow of internationalization lemming-like towards its final destination.
Carry photos from home, and talk about what it's like. If someone asks you to have a cup of coffee, go for a drink, or even attend one of those interminable ceremonies you'll become so adept at sleeping while sitting upright in. Say yes as often as you can! Don't underestimate the influence of having a positive attitude and trying to communicate with your peers. Meeting new people with a different outlook on life was, after all, one of the reasons you've ventured here, right?
Make a Poster about Yourself and/or Your CountryYour first weeks of the school year may well be reminiscent of Princess Diana and the Paparazzi, although hopefully not as fatal. Everyone at school will want to know everything about you - Who are you? Where do you come from? What's it like there? What did you do there? How tall are you? What's your favorite Japanese food? Then, inevitably questions will drift into - Are you married? Do you have a boyfriend/girlfriend/both? For a short time you may well have celebrity status. Don't worry, however, this will wear off. You will be treated like a star until it's realized that you're just as boring as everyone else. One way to hasten the demise of these gentle enquiries, and to pad a slow day made even slower by pointless busy work, is to put the information up on the wall for all to see.
Get together as many pictures of yourself and your home as you can. A quick trip to a colour photocopier, the brightest marking pens you can find, a large piece of card, a little imagination, and hey presto! You've got yourself a poster. If you ask for the pens and stuff the school will probably give them to you if you say that you want to make a poster.
When making the poster consider, only include information you are comfortable sharing with strangers.
If you don't want people to know it, don't write it up. While the poster is probably not the best place to out yourself, you should still be able to produce a fun and informative expurgated autobiography.
Also, consider the timing of when to put the poster up. You don't want to shoot your self-introductions in the foot by having everyone know everything about you before they've met you. What fun is that self-introduction standard - the "Guess my age" game - if everyone is under whelmed by the fact that you're actually only twenty-three when a lifestyle of Marlboro blues and vodka shots has given you the appearance of an over-the-hill thirty-something?
