Budget as a student

Hi, just here to ask about how much money I should have per month as an exchange student in Osaka. Excluding rent costs, since I'll be staying at the school's dorm. I'd have around 230k yen per month. I don't cook much so I plan to eat out/get konbini food, and I plan to do a fair bit of shopping and traveling. Does this seem realistic? I currently spend around that much here in Finland.
