What is the cost of living in Singapore, Hong Kong or Japan?

As part of my degree programme, I will be taking an international study year, most probably in Singapore, Hong Kong or a Japanese city (not Tokyo).

I am requesting estimates (in local currency) of costs for the following:
1. Rent on a small apartment/room, plus utilities: electricity, water, etc.
2. A week’s worth of food from the shop.
3. Eating out for a cheap breakfast/lunch/dinner.
4. Public transport.
5. A drink in a bar.
6. A beer from the shop.

Thanks, and if you’ve any other advice about living in one of these locations, now is the time! =}
