Japan's Minpaku Boom: Tokyo's Short-Term Rentals Grew 67% in 16 Months, with 87% Foreign Guests

• Tokyo's registered minpaku (short-term rental) properties grew from 7,527 (April-May 2024) to 12,576 (August-September 2025) — a 67.1% increase in 16 months. Foreign guests using Tokyo minpaku grew even faster: from 72,543 to 134,747 — an 85.7% increase over the same period.
• Foreign guests now account for 86.8% of all Tokyo minpaku guests (Aug-Sep 2025), up from 73.2% in April-May 2024. The Japan short-term rental market is predominantly a foreign inbound tourism product — not domestic travel — which puts it in direct competition with hotels serving international visitors.
• Kyoto's minpaku supply grew 40.8% (628 to 884 properties) in 16 months, but foreign guest penetration is highest here: 77.6% of Kyoto minpaku guests are foreign (Aug-Sep 2025), up from 70.9%. In peak periods Kyoto minpaku houses thousands of foreign guests who would otherwise book hotels.
• Summer 2025 saw a divergence: Tokyo's foreign guest count peaked at 165,262 in June-July 2025, then fell to 134,747 in August-September. Kyoto shows the inverse — foreign guests fell from 19,782 (Jun-Jul 2025) to 8,858 (Aug-Sep). The summer heat peak shifts guests from Kyoto to air-conditioned Tokyo stays.
• The competitive threat to traditional hotels is structural. 12,576 Tokyo minpaku properties at an average of 2 rooms per property represents approximately 25,000 effective room-equivalents — roughly a 5.4% addition to Tokyo's licensed hotel room supply — operating outside the traditional hotel price and inventory management system.

Japan's Minpaku Boom: 12,576 Tokyo STR Properties and Growing

Japan's short-term rental market — known as minpaku — has undergone a structural expansion since the Minpaku Act (June 2018) created a licensing framework for property owners. The COVID-19 pandemic compressed activity sharply in 2020-2022, but the recovery since 2023 has been dramatic. In Tokyo alone, registered minpaku properties have grown 67% in 16 months. This report analyses data from Japan's Ministry of Health, Labour and Welfare minpaku statistics, covering bimonthly reporting from April 2024 through September 2025.

Supply Growth: Rapid and Accelerating

Growth accelerated sharply in H1 2025, adding nearly 2,800 properties in a single bimonthly period. Osaka and Kyoto show more moderate growth:

Foreign Guest Dominance

The guest data reveals who is using Japan's minpaku market — overwhelmingly foreign inbound tourists.

Tokyo foreign guest share:

In August-September 2025, 86.8% of all Tokyo minpaku guests are foreign visitors — a share that grew from 73.2% in April 2024. The Japan short-term rental market is not primarily serving domestic travelers. It is competing directly with hotels for international visitors.

Kyoto foreign guest share:

Seasonal Patterns by City

Tokyo: Foreign guest count peaked in June-July 2025 (165,262), then pulled back to 134,747 in August-September — counterintuitive for a traditionally strong August. Possible factors: Japanese domestic summer travel reducing international guest share, and the extreme 2025 summer heat shifting some visitor preferences toward higher-specification hotel cooling.

Kyoto: Shows the inverse. June-July 2025 had 19,782 foreign minpaku guests — the highest in the dataset — but August-September dropped sharply to 8,858. Kyoto's outdoor-heavy tourist itineraries (temples, bamboo groves, geisha districts) lose appeal in extreme summer heat, and many machiya-style minpaku properties have inferior air conditioning compared to modern hotels.

Osaka: Relatively stable with 8,386-12,241 foreign guests across study periods. The Osaka market is more balanced between foreign and domestic use than Tokyo or Kyoto.

The Competitive Threat: How Significant?

Supply equivalence calculation:

• 12,576 Tokyo minpaku properties at average ~2 rooms = approximately 25,000 room-equivalents
• Tokyo's total hotel room supply (greater prefecture): approximately 460,000+ rooms
• Minpaku competitive supply as % of total: approximately 5.4%

At 5.4%, the aggregate impact seems modest — but the threat is concentrated:

Neighbourhood concentration: Minpaku clusters in Shinjuku, Shibuya, Asakusa, and Ueno. In these micro-markets, competitive supply proportion may reach 15-25%.

Peak-period pricing pressure: Minpaku properties do not use yield management. They are often priced below market on OTA platforms during peak demand, absorbing demand that would otherwise book hotels at premium rates. This is most damaging during cherry blossom and Golden Week.

Segment displacement: Minpaku competes hardest for the mid-market international leisure segment ($150-300/night equivalent) — the volume segment for most Tokyo hotels outside the luxury tier.

Growth trajectory: At half the 2024-2025 growth rate, Tokyo minpaku reaches 16,000-18,000 properties by end of 2026, representing 7-8% equivalent supply.

Revenue Management Response

Differentiate on services: Minpaku cannot offer 24-hour front desk, daily housekeeping, on-site F&B, or concierge services. Marketing these explicitly reinforces the value differential for the international visitor segment.

Rate intelligence: Monitor Airbnb/Vrbo pricing in your catchment area as part of competitive rate intelligence. When minpaku prices spike during events (concerts, sport, festivals), hotels have greater pricing latitude than they may realise.

Minimum-stay strategies: 2-night minimums during peak periods reduce the one-night stopover segment most likely to comparison-shop against minpaku.

Group and MICE focus: Minpaku cannot accommodate conference groups or tour groups. Hotels with strong group capability insulate themselves structurally from the STR competitive dynamic.

FAQ

Q: What regulations govern Japan's minpaku market?

A: The Minpaku Act (2018) allows hosts to rent residential properties for up to 180 nights per year. All properties must be registered with prefectural governments. Local municipalities can impose additional restrictions — Kyoto restricts minpaku in central residential zones during certain periods.

Q: Is the 67% Tokyo growth rate sustainable?

A: Unlikely at full speed. The 180-day annual cap limits operator economics. Based on STR market cycles in other cities (Barcelona, Amsterdam, New York), sustained growth above 20% YoY is unusual beyond 3-4 years. A market equilibrium will emerge as delistings of underperforming properties offset new registrations.

Q: How does the minpaku data relate to Airbnb listings?

A: Most registered minpaku properties are listed on Airbnb, Booking.com, and Japanese platforms (STAY JAPAN, minn). The government statistics count licensed properties only — there is an estimated unlicensed market not reflected in this data. The 12,576 registered count is a floor, not a ceiling, on total competitive supply.
