Who approves changes to your Tokyo apartment booking?

If a company says “the building won’t allow it,” ask which rule applies and who can say yes or no to your request. They may be able to offer another option. You shouldn’t have to work out how the companies behind your booking fit together.

The roles can be combined or separate

The owner, a company renting the home from the owner, the booking team and the building’s management association can have different responsibilities. One company may handle several of these jobs, or your booking may involve several companies. Tokyo monthly apartments don’t all work the same way.

Start with the agreement. Who is renting the home to you? Who takes payment? Who handles building maintenance? If the company is a tenant subletting the apartment, landlord consent matters. The law requires that consent, so the booking team may need the landlord’s agreement before saying yes to how you want to use the home.

A company named on an elevator maintenance notice may only look after the elevator. Ask the company you booked with who handles your request, rather than calling a number you happen to find in the lobby.

The landlord and building association answer different questions

Japan Tourism Agency's minpaku filing guidance gives a concrete example. A tenant applying to run a minpaku, a home used for paid short stays, needs evidence of the landlord's consent. For a unit in a building with separately owned apartments, the application also needs the condominium rules; if those rules say nothing about the business, it needs evidence that the management association does not intend to prohibit it.

Suppose the booking team sends you the owner’s permission to run a minpaku, but says it’s still checking with the building’s management association. The owner’s permission doesn’t settle the association’s rules. Even if the price is good and the team is willing to take your booking, ask for confirmation that the paperwork about those rules is complete before you book.

The reverse matters too. A building may allow minpaku, but the landlord still has to agree to their tenant running one. If you’re signing an ordinary residential lease, ask which rules apply to that rental; the same lodging paperwork may not be needed. Start by asking what kind of agreement you’ll sign and how the apartment is rented out.

Different requests need different answers

For an extra night, the questions may be availability, the existing agreement and the price. For an additional occupant, the company also needs to consider how many people may stay and guest rules. For a pet or smoking request, the unit or building policy may rule it out entirely.

These aren't necessarily negotiable. Ask for an available option that meets your need rather than assuming the right phrasing will produce an exception. If a pet is essential to your trip, for example, a confirmed pet-accepting home is more useful than a pending exception at one that advertises a ban.

Minimum stay and occupancy need careful handling

The company may set a minimum stay for the kind of rental it offers. That doesn’t mean every stay under thirty nights is illegal. The 2018 national guidance on short-term rental listings uses one month as a starting point when considering whether a rental needs a lodging licence. It also considers how the property is run and who is responsible for keeping it clean. A local authority may already use a different stay length for that decision and continue to use it.

If your dates fall below a stated minimum, ask what can lawfully be booked and what the full charge would be. Don't ask the company to describe one stay in the contract and knowingly operate a different arrangement to avoid a rule.

If you want a visitor or another person to stay, say who they are and which nights they’ll be there. Adding a name to the booking doesn’t make a visitor ban go away. If the company agrees, ask whether it needs to change the guest list or agreement and whether there’s an extra charge. See the pre-booking email guide for the other terms worth settling together.

Make the request easy to answer

A short, specific message gives the team enough information to check:

I'd like to change [current arrangement] to [requested dates/occupants/other detail]. Is the restriction part of my agreement, the building rules or your booking policy? If approval is possible, please confirm who will review it, any extra cost and when I should expect a decision. I need a confirmed plan by [date].

If you booked through a platform, keep the decision in its messages as well as in any separate email.

Keep a fallback while approval is pending

Imagine you need nine more nights after a fixed-term stay. The calendar appears open, but the team says an extension requires review. Ask whether those dates are being held during the review. If not, price another home while waiting.

An illustrative comparison might be ¥60,000 to remain in place against ¥55,000 elsewhere plus ¥10,000 for moving and luggage. With those prices, staying would cost ¥5,000 less and save you a move. But you still need the company to confirm the extra nights before you can rely on them.

Once the company agrees, ask for the new agreement and payment deadline. If it says no, ask what other homes or dates it can offer.

Before you act on an answer, check that it confirms the apartment, dates, people staying and price in writing. Save it with your agreement. If approval is still pending when you need to decide, make sure your fallback is available and check what changing the original booking would cost.
