There’s a huge variety of fees that need to be paid when renting a new apartment in Japan. In addition to an advance payment of your first month’s rent, there’s insurance, the security deposit, the realtor’s fee, and the dreaded “key money,” basically a sign-up cost that you pay to the landlord for the privilege of being allowed to start giving him money on a monthly basis.
Add it all up, and you’ll probably find yourself out several months’ worth of rent before spending the first night in your new home. But there’s a nice upside if you chose to go through one unique realtor, because while you’ll still have some fees to pay, you’ll also get a nice housewarming present in the form of several hundred dollars’ worth of anime merchandise.
