A monthly rent of ¥60,000 but initial costs of nearly ¥300,000? A line-by-line breakdown of the deposit, key money and the other costs on your quote.

A studio flat with a small kitchen

"Why does a flat in Fukuoka with a monthly rent of ¥60,000 come with a quote that adds up to nearly ¥300,000?"

This is often the first reaction when clients from Hong Kong and Taiwan come to me for help. When renting in Hong Kong or Taiwan, we're used to the "two months' deposit plus one month's rent" model, but in Japan, on top of the rent, there is a hefty sum of "initial costs" to pay when you sign the contract. Today, let's break down the mysterious terms on this quote so you can spend your money where it counts and no longer feel lost.

The big two: deposit vs. key money

These two terms are the most commonly confused, but just remember that one is "held for you" and the other is "given away":

  • Deposit (shikikin, 敷金): This is the familiar security deposit. You hand this money to the landlord as security; in Fukuoka it is most commonly one month's rent. When you move out, the "cleaning fee" or "repair costs" agreed in the contract (restoration on moving out, genjō kaifuku, 原状回復) are deducted, and the rest is returned to you.
  • Key money (reikin, 礼金): This is a uniquely Japanese custom; it literally means "a gift to thank the landlord for renting the property to you". Key point: this money is not refundable.
Note: Although more and more properties in the Fukuoka market now have no key money, paying 1–2 months' key money is still normal in the following three situations, and a very small number of properties even ask for as much as 3 months' key money:
  1. Larger family-sized layouts (such as 2LDK, 3LDK and above).
  2. New builds (just completed) or fully renovated properties.
  3. High-end apartments in popular areas.

"Hidden" costs on the quote

Besides the deposit and key money, I divide the other costs into two groups, "essential" and "optional", to help you see clearly which money you "must pay" and which is "open to negotiation".

Essential costs (almost unavoidable)

  1. Two months' rent paid in advance: This usually covers pro-rated rent for the first month (calculated by the day) plus a full month's rent for the second month. This is the main reason the first payment looks especially large.
  2. Common-area fee / management fee: A maintenance fee for the building's common areas (lifts, cleaning).
  3. Brokerage fee: One month's rent plus consumption tax (10%).
  4. Fire insurance: Compulsory; about ¥20,000 every two years, rising or falling with the size of the property.
  5. Lock replacement fee: From about ¥20,000 for a standard lock; for keys with automatic sensor functions, or at some high-end apartments, it can be as much as ¥100,000.
  6. Guarantee company fee: Usually 50–100% of the total rent.
  7. 24-hour support service: About ¥800–1,500 a month. Provides emergency maintenance support late at night or on holidays (for example, water leaks or lost keys).
  8. Neighbourhood association fee: A community fee of about ¥200–500 a month.

"Optional services" added by the management company (mostly open to negotiation)

Some items are actually added by default by the management company:

  • Interior disinfection fee: About ¥15,000–20,000, mainly to prevent insects and other pests.
  • Air-conditioner cleaning fee: Cleaning the air conditioner before you move in.
  • Water purifier: A water filter for the kitchen, about ¥1,000 a month.
  • Security lock / fire extinguisher: Anywhere from a few thousand yen to ¥10,000.

Doing the maths: how much do you need to have ready?

For renting in Fukuoka, a general rule of thumb is: initial costs come to roughly 4 to 6 times the monthly rent.

  • For example: If the monthly rent is ¥60,000, you should budget about ¥240,000–360,000 for initial costs.

So…

When you look at a quote, don't just look at the monthly rent. Divide the total amount by the number of months you expect to live there; that is your real cost of living there.
