Move-in costs in Tokyo, line by line.

The size of Tokyo's move-in bill is mostly historical. After the war, central Tokyo was rebuilt under chronic housing shortage, and landlords held the leverage. Two of the largest line items still on a modern lease, key money (礼金) and the security deposit (敷金), come from that period. Key money is a non-refundable gift to the landlord, traditionally one or two months of rent. The deposit is refundable, but the landlord deducts repair and cleaning costs when you leave.

A second layer is the brokerage system. Most central Tokyo rentals are listed through a real-estate agent who collects a commission from the renter, capped by law at one month's rent plus consumption tax. The legal cap is firm but the practical floor is not. Well-priced listings sometimes carry no agent fee at all, especially when the agent represents the landlord directly.

A third layer is the guarantor system. A renter without a Japanese guarantor (someone who agrees to cover unpaid rent) is routinely required to use a guarantor company instead. The fee is usually about 50 percent of one month's rent at signing, plus a smaller renewal every year or two.

Stack those three on top of the first month of rent, the management fee, fire insurance, key replacement, and a move-in cleaning charge, and four to six months of rent is a reasonable baseline.

These are the lines you should expect on almost any central Tokyo lease. Amounts vary by property, but the categories themselves are stable enough that you can read a contract from any agent and find them all in roughly the same order.

First month's rent and the management fee are simply paid in advance. If you move in mid-month, you'll see a prorated daily rent line on the contract instead.

The security deposit (敷金, shikikin) is held by the landlord against repair costs at move-out. In Tokyo most listings ask for one month, occasionally two, sometimes zero. The portion that is genuinely refundable depends on the wear-and-tear assessment and any agreed amortisation (see hidden surprises below).

Key money (礼金, reikin) is the line most foreign to non-Japanese renters because there is no Western equivalent. It is not a deposit, not a fee, simply a one-time payment to the landlord. Listings range from zero to two months. Zero-reikin units exist in every price band and are worth filtering for.

The agency fee (仲介手数料) is capped by the Real Estate Brokerage Act at one month's rent plus 10 percent consumption tax. Most agents charge the cap. Some charge half a month or zero, especially on units the agency itself manages.

The guarantor fee (保証会社利用料) replaces the older personal-guarantor system. The company underwrites your rent in case of default, in exchange for an initial fee around half a month's rent and a small annual renewal. For renters without a Japanese family member able to guarantee, this is no longer optional in practice.

Fire insurance (火災保険) covers personal contents and minor liability for the unit. The landlord typically requires a specific provider, with a two-year premium of around ¥15,000 to ¥25,000.

Lock change (鍵交換費用) is a one-time charge to replace the entry cylinder so previous tenants cannot return. ¥20,000 to ¥40,000 depending on the lock type.

Move-in cleaning (ハウスクリーニング) covers a deeper clean than the standard turnover. ¥30,000 to ¥60,000, occasionally bundled into the deposit's amortised portion.

Three line items often surface late in the application and surprise renters who only studied the headline numbers.

Negotiation works best when you know which lines have any room. Asking for everything reads as inexperienced and often loses goodwill on the lines that could have moved.

Key money is the most negotiable line. Many listings advertise zero reikin already; on units where reikin is one or two months, a polite request through your agent succeeds often enough to be worth asking. Move-in cleaning and lock change can sometimes be reduced or waived, particularly on units that have sat on the market for a few weeks. The agency fee is capped by law, occasionally waived entirely on landlord-direct listings, but rarely negotiated downward case by case.

Insurance, the guarantor company, and the management fee are essentially fixed. The landlord chooses the provider, the company sets the rate, and the management fee reflects the building's actual cost. Asking for changes here usually goes nowhere.

Here is what the breakdown typically looks like for a representative unit. Your actual numbers will vary by property, but the shape is reliable.
