Can you find a rental apartment in japan for 50000 yen?

50,000 yen monthly rent is probably a bit above average for a single person living alone. However, there will usually be additional fees to pay, including key money, deposit, lease renewal fees, insurance fees and utilities. These can vary quite a bit so it's hard to give an estimate of how much they add to the cost, but the bottom line is, Y50,000/month is quite possible.
