Key money and deposits: the real upfront hit
Japan's rental system is unlike most of Asia. On top of a standard deposit, many landlords still charge key money (reikin) — a non-refundable gift to the landlord, often one to two months' rent — plus an agent fee of about one month's rent. Add these together with the deposit and first month's rent, and move-in costs can reach three to six months' rent in one lump sum.
Some employers, especially larger eikaiwa chains and ALT dispatch companies, help arrange apartments or offer company housing that softens this hit significantly — always ask exactly what's covered before comparing job offers on salary alone.
