Japan housing inventory continues to climb faster than sales

The number of properties registered for sale through Japan’s Real Estate Information Network System, or REINS, continued to increase in June 2026, outpacing growth in reported sales.

Key Points:

The number of properties registered for sale on REINS increased 4.7% year on year in June, while reported sales rose 1.0%.

The figures suggest that supply recorded on the agent-only network is building faster than transactions, although they do not by themselves establish a nationwide buyer’s market.

Rental activity recorded through REINS continued to decline across new registrations, reported transactions and total inventory.

Nationwide REINS usage data released by the Real Estate Transaction Promotion Center Foundation on July 21st showed that for-sale inventory increased 4.7% from a year earlier to 443,165 properties.

Reported sales rose by a more modest 1.0% to 22,518, marking the 20th consecutive month of year-on-year growth.

The figures indicate that inventory recorded on REINS is accumulating faster than transactions. However, additional indicators - including pricing, time on market and regional conditions - would be needed to determine whether negotiating power is shifting decisively toward buyers.

What is REINS?

REINS is a property-information network operated by four organizations designated by Japan’s Ministry of Land, Infrastructure, Transport and Tourism.

Real estate companies use the system to share listings and transaction information with other member firms.

The public cannot search the full system directly. Its statistics therefore provide an important view of activity handled through participating real estate companies, but they should not be treated as a complete count of every property available or every transaction completed in Japan.

For-sale inventory increases for seventh month

New for-sale listings on REINS edged down 0.5% year on year to 123,255 in June. This was the sixth straight month in which fewer properties were newly added to REINS than a year earlier.

Despite the decline in new listings, total for-sale inventory increased for a seventh consecutive month.

One possible explanation is that existing listings are remaining registered for longer, or that properties are being added faster than completed transactions remove them from the system.

For buyers, a larger selection of registered properties may create more opportunities to compare location, condition and price.

For sellers, rising inventory may increase competition, particularly where similar properties are available nearby.

Nevertheless, the continued increase in reported sales indicates that demand recorded through REINS has not stalled. The data point to a gradual change in the balance between listings and transactions rather than a clear nationwide transition to buyer-favourable conditions.

Overall REINS activity remains lower

Across properties offered for sale and rent, new registrations fell 6.8% year on year to 310,414.

This was the 27th consecutive month of decline.

Reported transactions decreased 7.3% to 52,288, marking a fifth consecutive monthly decline.

The total number of listed properties fell 2.9% to 779,136, extending its decline to 25 months.

The contrast between the overall figures and the for-sale segment was largely associated with continued contraction in rental registrations recorded through the system.

Rental registrations continue to decline

New rental listings on REINS fell 10.6% year on year to 187,159, their 52nd consecutive monthly decline.

Reported rental transactions decreased 12.7% to 29,770, marking a sixth straight monthly fall.

Total listed rental inventory declined 11.4% to 335,971, its 46th consecutive month of contraction.

These figures show reduced rental activity recorded through REINS. They are not a comprehensive measure of Japan’s rental market, as rental properties are also advertised and transacted through other industry networks and consumer-facing platforms.

Why this is significant

The June figures show that Japan’s residential sales and rental segments are moving in different directions within REINS.

Rental listings continued to lessen, while the number of properties listed for sale is increasing even as reported sales remain above their year-earlier level.

For international buyers and investors, the national totals are best treated as an early market signal rather than a direct guide to an individual purchase. Conditions vary substantially by region, property type, price range and building age so always consult a licensed realtor for your property specific needs.
