Its been a while since I've looked at Japanese etiquette but from what I can remember this may help.
Basically, you bow, bending from your waist with a straight back. Men usually keep their hands in their sides, and women usually put their hands together on their thighs with their fingers touching.
There are a range of bows for different situations but there are 2 that you should keep in mind Nick, the first one is to bow to 30 degrees (you may want to try this a couple of times beforehand as it will feel like a lot). Usually this is reserved for people of higher ranking that you but it should give a good first impression when you aren't sure where they are on the ladder in relation to you.
The second one is to bow to 45 degrees and is used when you really bugger something up (not that we are expecting you to be in the middle of a huge disaster or anything
) You won’t need to use this one very often, if you’re lucky.
Bear in mind that the Japanese don't expect foreigners to know the intricacies of bowing and they won't expect you to bow perfectly. The most important thing is that you don’t make it look rigid and unnatural, just try to relax and enjoy yourself.
On the business front it could be worth boning up on Kaizen and the latest incarnation of Six Sigma for the quality aspect.
