Why Tokyo furnished rentals often start at a month

If your Tokyo trip is nearly a month long, you may keep finding furnished apartments whose minimum is slightly longer than your stay. Before adding nights, ask for the earliest checkout date the company accepts and the full price from your intended arrival.

A monthly minimum may reflect the company's rental arrangement and booking policy. It doesn't mean Japanese law turns every accommodation stay into a residential lease on the thirtieth night.

What the one-month guidance says

A 2018 joint government notice recommends that local authorities generally treat stays shorter than one month as lodging. An authority already using a different period can keep using it.

For a website to list a home as a residential rental under the notice, the planned stay must be at least as long as the period the local authority uses as its guide. The listing must also say that you will sign a lease to rent the home and that the company does not take responsibility for keeping it clean and hygienic. A month-long booking alone does not remove the need for any required lodging licence.

MHLW's explanation of the Hotel Business Act looks at who is responsible for keeping the property clean and hygienic, and whether the person lives in the room as their home. It also includes a lodging category with charges calculated in periods of one month or more. A long booking can therefore still be lodging.

If a listing explains its legal status only by saying it has a 30-day minimum, ask which agreement you'll sign and how the home is managed. Our guide to the government notice walks through its conditions.

A calendar month is not always 30 nights

Different companies can express their minimum differently. Oakhouse advertises apartments from one month. MetroResidences' FAQ is more specific about its own policy: its initial minimum is a calendar month, with an example of 10 April to 10 May meeting the minimum while 10 April to 9 May does not.

Ask for the full price for your intended stay, including any extra nights the minimum requires you to pay for. Multiplying the advertised daily rate by the nights you need may understate the bill.

A platform can use a different threshold again. Airbnb applies its long-term cancellation policy to reservations of 28 nights or more. A 29-night Airbnb booking already uses those terms, even though the same dates may fall short of another company's calendar-month minimum.

Is it cheaper to pay for the unused nights?

Suppose you need 27 nights. An apartment company might offer a monthly contract even if you leave earlier, but ask it to agree to that plan in writing and quote the full price. MetroResidences describes that possibility under its own minimum-stay policy; confirm the arrangement for the apartment you're considering.

Here is a made-up comparison with mandatory charges included:

In this example, paying for the longer apartment period still costs ¥27,000 less. If its mandatory charges instead take it to ¥270,000, the shorter booking costs ¥27,000 less.

Then compare what the homes include. A kitchen helps only if it has the equipment you need. A hotel rate with housekeeping may save you work. Keep a refundable deposit separate from the total cost, but include it in the cash you need upfront.

Leaving early and shortening the bill are different

Tell the company if you intend to hand back the apartment before the paid period ends. Ask when to return the keys, whether you can re-enter after checkout and how the deposit will be returned. Leaving the apartment early doesn't necessarily cancel the remaining payment or entitle you to a refund.

Also ask what happens if your trip changes before arrival. If your work assignment might be cancelled, compare what each company would charge if that happened. An apartment that costs less for the full stay may cost more to cancel. Ask what you would owe if you cancelled on the date you expect your plans to be settled.

If you may stay longer, ask whether extensions can be shorter than the initial minimum. Some companies distinguish the first booking from additional nights. Confirm that the apartment is available for the extra days too.

Keep the housing dates separate from permission to stay

Check how long you are allowed to stay in Japan before choosing your apartment dates. Paying for a month, signing a lease or extending an apartment booking doesn't itself extend that permission. If you must leave Japan before the company's minimum rental period ends, explain when you will leave and ask whether it accepts that plan before paying.

Keep the company’s written agreement about your departure date, key return and any refund with your booking.
