It was only last week i walked into a classroom and found on the secondary blackboard at the back of class had mnay of the students chalk drawings of various male and female body parts and a naked lady that took up half the board - all labeled in japanese. And because they knew i didnt know japanese they decided to share some of there newly learnt words...in this case i ignored those students and continued with the class whilst the JTL (japanese language teacher)  erased the boards.

Every week its always the same few who act up in the one class... occasionally i do find it funny but if i laugh it will make it worst so i usually give myself a reason to write on the bord and smirk a little whilst they cant see me...but the best method is to give them that stern look of disaproval...they will stop and it will give you 5 mins to teach before they act up...Even today i was trying to teach giving directions which is something that would have taken maybe 40mins but i only just managed to get half way through the lesson plan when the bell rang because of the few kids that like to act up.

As for the local customs there are many in japan...the main one is dont wear a black suit with a a white shirt and then a whist or black tie - wearing it with a white tie means your going to a wedding and a black tie means funeral - best to wear a coloured tie.

Dont use a mobile phone on public transport unless you have to and then move to the end of the cart and talk quietly, have the phone on silent as well - texting is ok.

MP3 players are OK but the person next to you should not be able to hear the music.

When saying someones name add 'san' to the end...there are others you can add but this is the one to use if in doubt.

Remember to bow - the deeper you bow the more respect you are giving - always great the teachers and students

This is just a few but there are loads
