Ometedou Thomas56. Restaurant food fetches around 600-1200 yen/meal. Although one could also subsist on eating Yoshinoya (around 270-500 yen/meal) good portion size (for me) or just cup noodles. Accomodation is approximately 5000 yen/day. Although there are some places that charge lower, I couldn't know if it would be that okay. Business class hotels of course draw around 20,000 yen/day.
