100,000 lets see:
if your renting: 30,000 - ( min) for room
if you ride a train everyday , just buy a monthly pass its cheaper and you can use it in between stations , but most of the time this is company provided .
but for non-work related train: get the "kaisuu" ticket, its cheaper, like if you buy the 1000yen pre-paid you have a 200yen extra
for food , if you cook you can really save, on working days I get only to spend 2000yen on food, cause I cook my food.
then theres fone and internet which I budget around 10,000 per month.
then water and electricity usually not more than 5000yen
alone I think I can live comfortably.. just have to know to budget your money well and know where to buy food and clothes.
but that also depends upon the lifestyle that you have/want.
oh by the way, this is Osaka way of budgeting
