The Impact of the 180-Day Minpaku Rule on Revenue
Under Japan’s Minpaku Law (the Private Lodging Business Act), the number of operating days per year is capped at a maximum of 180. In other words, for the remaining 185 days, you cannot legally earn accommodation revenue as a minpaku. This 180-day rule fundamentally shapes the profit structure of any minpaku business, and in regions like Hokkaido—where demand fluctuates dramatically by season—how you utilize the non-operating period can make or break the entire venture.
Let’s say your average nightly rate is ¥15,000 and your occupancy rate is 80% over the 180 operating days. In that case, annual revenue would come to roughly ¥2.16 million. However, fixed costs such as rent, utilities, and cleaning fees continue to accrue across all 365 days. If you try to cover a full year of expenses with only 180 days’ worth of revenue, your profit margin gets squeezed dramatically. That’s exactly why deciding in advance “what to do with the remaining 185 days” becomes the lifeline of a successful minpaku business.
Why the 185-Day Gap Is Especially Serious in Hokkaido
Hokkaido has two major high-demand seasons—summer outdoor activities and winter skiing—but between them lie clearly defined off-peak periods. Specifically, the stretch around Golden Week in April–May and the shoulder season in October–November tend to see fewer tourists and lower room rates. If you concentrate your 180 operating days entirely on peak season, the off-peak periods end up overlapping directly with your 185-day gap, making it easy for your property to sit idle for extended stretches.
On top of that, heating costs for Hokkaido properties during winter can easily reach ¥30,000–¥50,000 per month. If you leave a five-month stretch from November through March completely idle, you’d rack up ¥150,000–¥250,000 just in heating and freeze-prevention costs alone. That’s a pure cost incurred with zero occupancy—a real drag on your annual bottom line. Given Hokkaido’s unique cost structure, it’s essential to concretely plan out how to supplement revenue during those 185 days.
Filling the Gap with Monthly Rental Conversion
How Monthly Rentals Work and Typical Revenue Levels
Monthly rental refers to renting out your property under a fixed-term lease of 30 days or more during periods when you can’t operate as a minpaku. Since this falls outside the scope of both the Hotel Business Act and the Private Lodging Business Act, it doesn’t count against your 180-day cap. In Hokkaido, there’s steady demand for one-to-three-month housing from ski instructors, seasonal agricultural workers, and people on temporary work relocations. A studio apartment in central Sapporo typically rents for ¥70,000–¥100,000 per month, while resort properties around Niseko can command ¥120,000–¥180,000 per month.
Suppose you fill 150 of your 185 non-operating days with a monthly rental at ¥100,000 per month—that’s roughly ¥500,000 in additional revenue. Combined with the ¥2.16 million from minpaku operations, your annual revenue reaches about ¥2.66 million. Even after subtracting annual fixed costs (rent ¥1.2 million + utilities ¥300,000 + other ¥200,000 = approximately ¥1.7 million), you’d still net a profit of ¥960,000. Simply converting “zero income” gap periods into “flat monthly income” dramatically improves your break-even point.
Key Contract Considerations When Converting to Monthly Rentals
With fixed-term leases, you need to provide written advance notice to ensure the tenant reliably vacates once the contract term ends. To avoid the risk of not getting the property back in time for minpaku peak season, set the contract end date two weeks before you plan to resume minpaku operations, giving yourself time for restoration and cleaning. Also, be sure to check your lease agreement with the property owner to confirm whether subletting is permitted. Some condominiums prohibit monthly rentals under their management bylaws, so upfront research is essential.
Eliminating the 180-Day Wall with a Hotel Business Permit
The Difference Between a Hotel Business Permit and a Minpaku Notification
Minpaku operated under a notification filed per the Private Lodging Business Act is capped at 180 days annually. However, if you obtain a permit under the Hotel Business Act (specifically, a simple lodging house license), you can operate 365 days a year—eliminating the 180-day problem entirely. Requirements for a simple lodging house permit include front desk facilities (or equivalent ICT-based alternatives), compliance with fire safety standards, and confirmation of the applicable zoning district. Renovation costs to meet these requirements typically run from ¥500,000 to ¥2 million.
Concrete Hurdles to Obtaining a Hotel Business Permit in Hokkaido
In many Hokkaido municipalities, hotel business permits are not granted if the property falls within a “residential-only zone.” In Sapporo, this includes Category 1 and Category 2 Low-Rise Exclusive Residential Districts and Category 1 Mid/High-Rise Exclusive Residential Districts—making conversion to a simple lodging house difficult for properties in these areas. On the other hand, if your property is in a commercial or neighborhood commercial zone, the barrier to obtaining a permit drops significantly. Checking the zoning designation at the property selection stage is a critical decision point that shapes your long-term revenue strategy.
The process of obtaining a permit—from document preparation through application and review—generally takes two to four months. Since you’ll need to conduct preliminary consultations with the health department, coordinate with the fire department, and handle building code use-change procedures simultaneously, this route requires considerably more time and cost than a simple minpaku notification. However, if you achieve 365-day operation, annual revenue based on our earlier calculation rises to approximately ¥4.38 million (¥15,000 × 80% × 365 days)—more than double what you’d earn with 180-day operation. In many cases, the initial investment can be recovered within one to two years, making this the highest-return strategy over the medium to long term.
Using Your Property as an Hourly Event Space or Photo Studio
Features and Revenue Examples of the Hourly Rental Model
Another option is to use your minpaku property as an hourly-rate space rather than for overnight stays. When rented out for meetings, workshops, photo shoots, parties, and similar purposes, it isn’t subject to lodging business regulations. Using platforms like Space Market or Instabase, you can set rates of ¥2,000–¥5,000 per hour. For detached houses in Hokkaido, spacious interiors and scenic, nature-rich locations can also generate solid demand as photo studio rentals.
Say you operate 6 hours a day at ¥3,000 per hour for 15 days a month—that’s ¥270,000 monthly, or roughly ¥1.35 million across five months out of your 185-day gap. Even after subtracting cleaning and equipment maintenance costs, this can outperform monthly rentals in some cases. That said, keep in mind it typically takes three to six months to build a stable client base, and you’ll need to be mindful of noise concerns for neighbors.
Property Conditions That Favor Hourly Rentals in Hokkaido
Hourly rentals tend to see stable demand for detached houses within a 30-minute drive of central Sapporo, or in locations like the Furano and Biei areas, which are popular filming and photography locations. Stylish interiors, parking for at least two vehicles, and reliable Wi-Fi are prerequisites for attracting bookings. As for initial investment, budgeting roughly ¥50,000–¥100,000 for equipment such as a projector and whiteboard should be more than enough.
Targeting Peak Seasons with Weekly/Seasonal Rentals
Hokkaido-Specific Short-Term Rental Demand
Hokkaido sees demand for stays lasting a week to several weeks from long-stay visitors during ski season (December–March), seasonal residents escaping summer heat elsewhere (July–August), and event staff working the Sapporo Snow Festival. These short-term rentals don’t fall under the Hotel Business Act and aren’t subject to the 180-day cap. In the Niseko area, weekly winter rentals have been known to close at ¥80,000–¥150,000 per week, making it possible to concentrate substantial revenue during minpaku off-season months.
The key is to work backward and design which periods to allocate to your 180 days of minpaku operation. For example, you might secure ¥200,000+ per month through weekly rentals in winter, then concentrate your full 180 days of minpaku operation during the summer peak season. By clearly dividing minpaku and weekly rental periods on an annual calendar and routinizing the cleaning, linen changes, and contract procedures involved in switching between them ahead of time, you can keep operational burden to a minimum.
Maximizing Annual Revenue by Combining Multiple Strategies
How to Build a Concrete Annual Schedule
The most effective approach isn’t to rely on a single supplemental strategy, but to combine the best method for each season. For example, for a 1LDK unit in central Sapporo, you might run minpaku operations for 180 days from June through November (roughly ¥2.16 million in revenue), switch to a monthly rental for 120 days from December through March (roughly ¥400,000 in revenue), and use the remaining 65 days from April to May as an hourly rental space (roughly ¥300,000 in revenue)—bringing total annual revenue to approximately ¥2.86 million.
If you estimate annual costs at ¥2 million—rent ¥1.2 million, utilities ¥350,000, cleaning and supplies ¥200,000, platform fees ¥150,000, and miscellaneous expenses ¥100,000—your annual profit comes to roughly ¥860,000. Compared to the profit from running minpaku alone for 180 days (about ¥460,000), that’s nearly double. Running this kind of annual profit-and-loss simulation before acquiring a property dramatically sharpens the accuracy of your investment decisions.
Practical Tips for Streamlining Operations When Switching Between Models
The most labor-intensive part of switching between multiple operating models is managing listing changes and cleaning/linen logistics. When switching from minpaku to a monthly rental, you’ll need to block off the calendar on platforms like Airbnb and create new listings on classified sites or weekly-apartment brokerage platforms. Doing this manually every time can eat up 5–10 hours a month, which is why outsourcing the whole process to a property management company often ends up being far more cost-effective.
