How much $$ do i need for 3 months?

I am planning to study in japan for 3 months next year. I already looked up the course and everything. But i am not sure how much i need to bring over there...Is AUS $10000 enough for 3 months? That is not include the course and accommdation (student apart). Thank you so much for answering my question!

It is hard to say if this is enough. This is a good amount of money, but depending upon where you end up living you could be pretty comfortable or just getting by.

Japanese apartments tend to be unfurnished, but student apartments might have some things. Japanese appliances/furniture can be expensive.

Japan has come a long way since the economic bubble. You can live very cheaply here if you are willing to go without. If you prepare your own meals, food can be very inexpensive. However, transportation is pretty expensive. Where I am, one-way subway tickets are at the minimum 200 yen. To get downtown, it is closer to 300 yen one way.
