Tokyo rental costs: compare the full cost of two homes

Why monthly rent is only one part of the comparison

Suppose two homes both meet your space, commute and move-in requirements. One has a lower monthly rent; the other has no key money. The useful question is what each arrangement requires now and what it costs over the period you actually expect to stay.

The figures on this page are deliberately fictional arithmetic examples. They are not Tokyo rent averages, surveyed offers, available apartments or fee recommendations. Neither example represents a UR property. Use the calculator with written quotes from providers, including any applicable tax.

Compare your two rental quotes

Two complete worked examples: every input is visible

For both examples, monthly amounts stay constant, the stay is 12 whole months, and one month of rent plus common fees is prepaid at signing. We assume ¥40,000 is retained from each deposit and no additional exit bill. This is a modeling assumption, not a statement about a permitted deduction.

The one-off setup allowance is paid at signing in these examples. All other unlisted expenses are excluded. Renewal, later insurance or guarantor fees and early-exit penalties are set to zero here; an actual quote may require them. The six-month comparison keeps the same initial charges and assumed refund, without assuming a refund of unused insurance.

Over 12 months, A saves ¥12,000 each month in recurring costs, or ¥144,000 in total. Its non-refundable initial charges are ¥97,500 higher. Subtract the extra initial charges from the recurring saving: ¥144,000 − ¥97,500 = ¥46,500. The assumed deposit loss is identical in both examples.

Over six months the recurring saving is only ¥72,000, so B becomes ¥25,500 cheaper. B also needs ¥70,500 less cash at signing in either scenario. A home that fits the annual budget may still exceed the money available at move-in.

What the calculator counts, and when

Prepaid rent appears in the upfront budget but is subtracted from remaining payments. It is not an extra month of rent. Likewise, enter a cleaning cost either as a reduction in the expected deposit refund or as an extra exit payment, according to how it is charged. Do not enter the same amount in both places.

The calculator uses whole months and constant monthly charges. It does not model partial-month occupancy, rent changes, exchange rates, interest, financing, opportunity cost or the timing of a deposit refund. It cannot check whether a quoted fee is lawful or recoverable. For a partial month or a complicated contract, use an itemized dated payment schedule instead.

Furniture, moving, internet setup, parking, renewal fees, annual insurance or guarantor payments, and early-exit charges are included only if you enter them. Put one-off amounts into the field matching when you pay them. Update the total for later fees each time you change the stay length. Keep unknown costs in a separate uncertainty note; entering zero excludes them rather than confirming they are free.

A Japan-specific comparison: quoted private rentals and UR

MLIT’s English apartment-search guide explains the cost categories encountered in a Japanese rental search, including the deposit, key money, agency fee, insurance, rent, common service fees and guarantor charges. The exact amounts belong to the individual quote; there is no universal fee package assumed here.

UR’s terms above come from its own FAQ, consulted 7 October 2026. Eligibility requirements and the actual property still need checking. This comparison does not establish current availability or that a UR home is cheaper overall.

The National Consumer Affairs Center of Japan distinguishes a refundable security-deposit balance from non-refundable key money, notes that some homes have no key money, and advises checking move-out restoration terms. Its February 2026 leaflet also recommends recording the home’s condition at move-in. Those distinctions explain why the calculator separates a deposit from a fee.

Turn a Tokyo shortlist into three comparable briefs

Send the same brief to each provider: desired move-in date, expected length of stay, number of occupants, floor-space needs, required furnishings, regular destinations and support language. Ask for the exact unit, an itemized quote and the date that quote was prepared. A general building description is not enough to price one home.

Two apartments near the same Tokyo station can have different walking routes and handover arrangements. Compare the exact addresses and your own schedule. A broad area label cannot substitute for that check. Property.tokyo provides this independent comparison resource; send rental enquiries to the accommodation provider.

Questions & answers

Does no key money mean a cheaper Tokyo rental?

Not necessarily. Compare all initial charges, recurring costs, expected deposit settlement and the length of stay. In our fictional examples, the no-key-money option is cheaper over six months but more expensive over 12 months.

Are these current Tokyo rental prices?

No. All numbers in the worked examples are fictional inputs chosen to explain the calculation. Replace them with dated quotes and clearly identified assumptions.

Is a security deposit counted as a cost?

It is included in cash needed upfront. Net cost subtracts the expected refund after settlement. Any retained amount is counted once; the refund is an assumption until the actual settlement.

Can I rent an apartment through property.tokyo?

No. This website publishes independent Tokyo property guides and comparison tools. It does not supply live listings or broker physical property.
