That off course highly depends on you, how you consume,....

when i lived in Tokyo i spend around 1000 to 1300 a day for food (i did some cooking) and around 350 a day for transportation (that will depend how far away from school you live).
10 hours will maybe get you 10000yen (before tax) if you are lucky, more if you teach/give private lessons.

If you are drinking you will have to safe some money, beer isnt cheap (around 500yen). Cigarretes are cheaper than in Europe (300yen). A night out with food and a few drinks can be 5000yen very fast.

I spend between 30000 and 40000 a month on other things like playing games at the arcade, sending some stuff home, buying a shirt, Shampoo, doing the washing,...... you can off course minimise that to maybe 10000 but you would want to have some fun as well!

My accomodation was 1850 a night wich included Internet, Electricity,.... I lived in a Guesthouse with shared Bath and Kitchen.

Also remember, the more free time you have, the more you will spend on the other things. I worked Monday to Friday 8 hours, so i didnt spend alot during the week.
