Your average expenses without counting rent as a single person?

Hi all, I am a MEXT scholar and I am trying to fit a 85,000円 rent (including maintenance fee but no utilities) monthly into my budget. I'd like to know how much do you spend monthly on food, utilities, insurance and miscelaneous expenses? My total budget is 147,000円

Any real life advice is appreciated, I have seen approximate grocery and transportation budgets but the ranges are too wide to be accurate. I will have the chance to move everywhere by bike or walking, so i am not really in need of having a transportation budget.

Thanks!
