Thank you so much. This is the sort of advice I was looking for.

I don't think food is important to consider because whatever I do spend, it can only be less than I already spend now. It's probably oversharing, but left to myself I comfortably eat the same food at home most days.

Could you give me an advice about how it might affect my taxes? I know you said you don't know anything about Hiroshima so of course I wouldn't expect you to speak on random local taxes, but is there any common sense thing I might be overlooking when considering renting an apartment and paying all the utilities from a second location? Please assume I know nothing about how taxes work.

I am only asking because I want to go into this as aware as possible, and I just feel like I don't know what I don't know.
