Running a short-term rental in Japan, you quickly notice something: some of your best guests are the ones who stay for weeks. Less turnover, no check-in chaos every two days, and somehow the property ends up cleaner at the end of a long stay than after a weekend party group. But blending monthly guests into your calendar alongside regular short stays isn’t as simple as just offering a discount. There are legal lines to be aware of, pricing math that changes, and OTA mechanics that work differently at longer timescales.

Here’s how I think about the long-stay mix at our properties — and what I’d tell any operator considering it.

TL;DR

  • Guests staying 30+ nights fall outside Japan’s minpaku (民泊) framework entirely — they become tenants under residential lease law, which changes your obligations significantly.
  • Monthly stays on Airbnb and Booking.com are operationally different: lower commissions, but platform protection is reduced.
  • The “right” long-stay mix depends on your property type, location, and seasonality — there’s no universal formula.
  • Revenue per night drops with discounts, but costs drop faster: fewer cleans, fewer guest communications, lower OTA fees.
  • Structure long stays correctly upfront; a month-long “guest” who refuses to leave is a very different legal situation than a weekend visitor.

What Counts as a “Long Stay” in Japan?

In the short-term rental world, “long stay” usually means anything from 7 nights to a full month or more. But Japan draws a hard legal line at 30 days.

Stays under 30 days (consecutive nights) fall under the minpaku law (住宅宿泊事業法) if you’re operating under a minpaku license, or under the ryokan/hotel licensing framework if you’re a full inn. The minpaku regime caps you at 180 nights per year per property — those nights get used regardless of whether the guest stays 1 night or 29.

Stays of 30 days or more cross into a different legal world entirely: residential tenancy. At that point, the Borrower Protection Act (借地借家法) applies, and your “guest” is legally a tenant. This means standard lease provisions, deposit regulations, and — critically — you cannot simply ask them to leave at the end of the agreed period the way you can with a hotel guest. You need a proper fixed-term lease (定期借家契約) to retain control over the end date.

This isn’t a reason to avoid long stays. It’s a reason to structure them correctly from day one.

Why the Revenue Math Often Works in Your Favour

Here’s a back-of-envelope comparison for a Tokyo property at ¥15,000/night:

4× 7-night stays 1× 28-night stay
Gross nights 28 28
Gross revenue ¥420,000 ¥294,000 (30% disc.)
Cleaning costs (×4 vs ×1) −¥40,000 −¥10,000
OTA commission (15% vs ~12%) −¥63,000 −¥35,280
Linen/supplies −¥20,000 −¥8,000
Net ¥297,000 ¥240,720

Short stays win on paper — but only when you fill every night. If you’re sitting at 70% occupancy, a 28-night guaranteed booking at 70% of your nightly rate still beats a month of gaps and partial weeks. The calculation tilts further in favour of long stays during shoulder season, when marketing effort is high and ADR is already under pressure.

How the OTAs Handle Long Stays

Airbnb has a dedicated monthly discount setting (separate from the weekly discount). Airbnb also reduces its host service fee for longer stays. The main downside: resolution centre support for long stays is noticeably weaker than for short ones — disputes over condition at checkout tend to be harder to escalate.

Booking.com doesn’t have a native monthly discount tier in the same way, but you can configure minimum-stay deals with rate adjustments. Monthly guests often book through the “non-refundable” or “genius” rates, which means you get paid regardless of early departure.

Direct bookings are where long stays really shine. Monthly corporate guests or digital nomads who find you through Google or word-of-mouth often prefer paying directly — especially if they want a simple bank transfer arrangement. We handle a meaningful chunk of our extended stays off-platform, which means zero commission and a direct relationship.

What Types of Guests Book Long Stays?

In Japan’s current inbound market, the long-stay guest tends to be:

  • Digital nomads on tourist visas who want a comfortable base for 2–4 weeks
  • Business visitors on project assignments (construction, consulting, tech) who need furnished accommodation near a job site
  • Language learners doing intensive courses in Tokyo or Kyoto
  • “Bleisure” travellers tacking leisure weeks onto a work trip

Domestically, workation (ワーケーション) travellers — Japanese remote workers escaping city heat or taking a regional trip — also skew toward 5–14 night stays. These guests are valuable: they’re familiar with Japanese norms, tend to be considerate with the property, and often rebook.

Does a Long-Stay Strategy Work for Every Property?

Honestly, no. Studio apartments in central Tokyo and Osaka work well for extended stays — walkable to everything, practical for a solo worker. A large house in Nara that sleeps six is designed for family groups who stay 3–4 nights, not a solo nomad who needs a desk and fast Wi-Fi.

At our properties we’ve found a rough 20–30% allocation to stays of 7+ nights as a healthy floor during low-demand months. During peak seasons (cherry blossom, Golden Week, autumn foliage), we restrict long stays to protect nightly rate — a discounted 28-night block that locks out peak dates is money left on the table.

If you’re taking 30-day bookings, use a fixed-term residential lease (定期借家契約 — teikil借家契約). This contract type, established under the 2000 revision to the borrower protection law, gives you a guaranteed end date with no automatic renewal rights for the tenant. Without it, you’re under a standard open-ended lease, and termination requires either the tenant’s agreement or demonstrable “justifiable cause” — a legal standard that strongly favours the tenant.

A fixed-term lease template drafted by a licensed real estate agent (宅地建物取引士) or judicial scrivener costs a few thousand yen and is worth every one of them.

FAQ

Q: Does taking a 30-night booking violate my minpaku license?

A minpaku license only covers stays under 30 consecutive nights. A 30-night-or-longer booking is a residential tenancy, not a minpaku stay, so it doesn’t consume your 180-night annual cap — but it also isn’t covered by the minpaku framework. You need a separate lease agreement.

Q: Should I offer monthly rates on Airbnb, or just negotiate directly?

Both. Listing monthly rates on Airbnb captures guests who wouldn’t otherwise find you, and Airbnb’s lower long-stay commission helps. But once a guest expresses interest, it’s worth offering a direct booking for the next stay — with a small additional discount to offset the platform fee. Most monthly guests are happy to repeat-book directly.

Q: How do I handle utilities for a monthly stay?

The simplest approach is all-inclusive pricing with a fair-use utility cap stated in the booking terms (e.g. ¥10,000/month electricity allowance included; excess billed at cost). This avoids monthly reconciliation headaches. For stays over 60 days, some operators add the guest to the electricity contract directly — more admin, but cleaner if consumption is unpredictable.
