Legal Differences Between Minpaku and Weekly Rentals: Comparing Revenue Models

Launching a short-term rental business without understanding the difference between minpaku (vacation rentals) and weekly apartments can leave you exposed to legal trouble and disappointing revenue. While these two business models might look similar on the surface, they’re built on entirely different legal frameworks, licensing requirements, and revenue structures. This article breaks down the differences between minpaku and weekly apartments—covering both the legal classifications and the underlying revenue models—so you can determine which option best fits your property and management style.

As demand for short-term stays continues to climb, more property owners are looking to turn vacant rooms into income. But the registration process under the Minpaku Act (Private Lodging Business Act) and the licensing required under the Hotel Business Act work very differently, with different restrictions attached. Weekly apartments, meanwhile, operate as an extension of standard lease agreements, putting them on entirely different legal footing. Understanding these distinctions correctly is the first step toward running a stable, sustainable operation.

Sorting Out the Legal Differences Between Minpaku and Weekly Apartments

Minpaku refers to a business model in which residential properties are used to provide lodging services. Legally, it falls into two main categories. The first is registered minpaku under the Private Lodging Business Act (commonly known as the “new minpaku law”), which caps the number of days a property can be used for lodging at 180 per year. The second is minpaku operated under a simple lodging license granted through the Hotel Business Act, which comes with no 180-day cap and allows year-round operation. Both are classified as lodging businesses, meaning that accepting payment to host guests requires either registration or licensing from the relevant authorities.

Weekly apartments, on the other hand, operate within the framework of standard lease agreements. Because they’re treated as “residences” rather than “lodging,” they fall outside the scope of the Hotel Business Act. The typical format involves accepting tenants for stays of roughly a week or more, and this model has become a go-to solution for corporate business travelers, construction workers on assignment, and people in temporary housing situations during a relocation. Given the nature of the contract, weekly apartments also aren’t subject to lodging tax.

Minpaku’s Legal Classification and Operational Constraints

Registration Under the Private Lodging Business Act

Enacted in 2018, the Private Lodging Business Act created a system that lets property owners and managers offer lodging services simply by filing a registration. The registration process itself is fairly straightforward—you just submit the required documents to your prefectural governor (or the head of a designated city or core city). That said, annual operating days are capped at 180, which inevitably means periods when the property can’t be used for lodging.

Many municipalities also impose their own additional restrictions on top of the national rules—for example, ordinances that limit operations in residential-only zones to weekends, or that ban minpaku outright in certain areas. Before moving forward with registration, it’s essential to check the specific ordinances governing your property’s location. Many condominium associations also prohibit minpaku in their management rules, so if you own a unit in a condo, checking with the management association is a must as well.

Licensing Under the Hotel Business Act (Simple Lodging)

Obtaining a simple lodging license under the Hotel Business Act frees you from the 180-day cap imposed by the Private Lodging Business Act, allowing year-round lodging operations. To get licensed, though, you’ll need to meet a range of requirements: installing fire safety equipment, securing sufficient guest room space (roughly 33 square meters or more as a benchmark, though this varies with guest capacity), and setting up a front desk or an equivalent alternative.

Initial costs tend to run higher than for registered minpaku. Once you factor in fire safety equipment installation, interior renovations, and licensing application fees, total costs often land somewhere between ¥1 million and ¥3 million. That said, year-round operation means significantly higher revenue potential. Properties with a hotel business license also face fewer restrictions on OTA (online travel agency) listings, making it possible to attract guests through multiple channels—Airbnb, Booking.com, Rakuten Travel, and more.

The Legal Classification and Operational Structure of Weekly Apartments

Positioned as a Lease Agreement

Legally speaking, weekly apartments provide residential services under a lease agreement. The Hotel Business Act defines “lodging” as “using a facility with bedding provided,” but weekly apartments operate on the interpretation that tenants are using the space as their “base of living,” which places them under the lease framework instead. As a result, they require neither a Hotel Business Act license nor Private Lodging Business Act registration.

That said, if a property is repeatedly rented out for extremely short periods (just a few days at a time), authorities may treat this as unlicensed operation of a lodging business. In practice, many operators set a minimum contract period of seven days or more—a common practice that’s also the origin of the term “weekly.” To avoid falling into a legal gray zone, it’s important to keep your contract terms consistent with how the property is actually being used.

Facility Requirements and Management Structure

Weekly apartments are typically furnished with everything a tenant needs for daily life—furniture, appliances, and household essentials. Refrigerators, washing machines, microwaves, bedding, and towels are standard offerings, and pricing often includes utilities. Cleaning is generally done only at move-out, so the daily cleaning typical of lodging businesses usually isn’t required.

When it comes to management structure, staffing a front desk isn’t mandatory, and many operators handle key handoffs by mail or through key lockboxes. This is possible because the Hotel Business Act’s front-desk requirement doesn’t apply here. That said, having a point of contact for emergencies is essential—being able to respond quickly to tenant issues directly affects the quality of your operation.

Comparing Revenue Models Side by Side

Differences in Average Rate and Occupancy

For minpaku (especially the hotel-business-licensed type), nightly rates in areas with strong tourism demand typically fall in the ¥8,000 to ¥15,000 range. Occupancy varies by location, season, and management quality, but it’s not unusual to see rates of 80–90% during peak season and 40–50% during the off-season. If you can maintain an average annual occupancy of 60–70%, monthly revenue starts to stabilize nicely.

For weekly apartments, weekly rates typically run from ¥60,000 to ¥120,000, which translates to roughly 20–40% more income per month than a standard lease. That said, vacancy periods between tenants are common, so actual monthly occupancy often lands around 75–85%. In urban areas with a strong base of corporate contracts, demand tends to be more consistent, making it easier to stabilize occupancy.

Differences in Initial Investment and Operating Costs

For registered minpaku under the Private Lodging Business Act, initial investment is mostly furniture and appliances, and some operators get started with as little as ¥300,000 to ¥800,000. With a hotel business license, you’ll also need fire safety equipment and interior renovations, often pushing total costs above ¥1 million to ¥3 million. Don’t forget to factor in ongoing platform fees—about 3% of revenue for Airbnb, and anywhere from 15–20% for some OTAs.

Initial investment for weekly apartments is similarly centered on furniture and appliances, but you’ll also incur monthly listing fees or commissions paid to brokers. Since cleaning only happens at move-out, you avoid the frequent cleaning costs (¥3,000–¥8,000 per turnover) associated with minpaku. The downside is that lower turnover makes it harder to deliberately create “revenue peaks.”

Legal Risk and Compliance Costs

Because minpaku operates under clearly defined laws, there’s real risk of administrative penalties if you fail to register or obtain the proper license, or if you run afoul of local ordinances. Operating minpaku without registration is a violation of the Hotel Business Act punishable by criminal fines (up to ¥30,000), and platforms will also suspend your listing. You’ll need to stay on top of regular legal and ordinance changes, which means ongoing time and cost devoted to compliance.

Because weekly apartments fall outside the scope of the Hotel Business Act, the risk of administrative penalties as a lodging business is lower—but it’s not zero if authorities determine that the operation is, in substance, no different from a lodging business. And because the arrangement is based on a lease agreement, there’s a risk of complicated legal proceedings if a tenant asserts occupancy rights or refuses to move out. Using fixed-term lease agreements is an effective way to manage this risk.

Differences in Target Guests and Marketing Channels

Minpaku’s core audience is tourists, inbound travelers, and domestic leisure guests, and bookings are driven primarily through OTAs like Airbnb, Booking.com, and Jalan. Since accumulated reviews directly influence booking rates, operators need to focus on delivering a high-quality guest experience. With frequent one-night turnovers, check-in support, cleaning, and linen changes happen often.

Weekly apartments, by contrast, appeal to business travelers on assignment, training program participants, people in temporary housing during a move, and healthcare workers. Demand often comes through corporate contracts or as part of company employee benefits, with bookings typically coming through a company’s own website, monthly-rental booking sites aimed at corporate clients, and partnerships with real estate agencies. Lower reliance on OTAs is a plus, since it reduces the burden of platform fees.

Which Should You Choose? Key Decision Points

If your property is located in a tourist area or near a major train station, minpaku (particularly the hotel-business-licensed type) tends to command higher rates and occupancy, giving it stronger revenue potential. On the other hand, properties in business districts, industrial areas, or near universities and hospitals may be better positioned to capture steady corporate demand as weekly apartments. The smart move is to research demand in your property’s surrounding area first, then decide which format is the better fit.

In terms of operational workload, minpaku involves frequent cleaning, check-in support, and guest communication, making a property management service a practical option. Management fees typically run 15–25% of revenue, but they significantly reduce the burden on owners. Weekly apartments involve less frequent turnover, which means less day-to-day work, but managing vacancy risk becomes the key challenge. Whichever format you choose, building the right operational systems is what ultimately drives stable revenue.
