Cost of living / Rough Number

Hello dear Japanese people,

I would like to stay in your wonderful country for one year next year on a Working Holiday Visa.

Since I do not necessarily plan to work (although I would have no problem doing so if the right opportunity comes up), I am currently trying to figure out how much money I would need.

I would love to hear from real Japanese people about how much you personally spend per month in total, including rent and other living costs. I would like to get a rough idea of the general monthly expenses in Japan.

I would also be interested to know how much the average Japanese person earns per month.

Thank you very much for your input. I am already looking forward to exploring your amazing country!
