Osaka Resale Detached-House Asking Prices Jump 13.0% in October to a Record; Up 6.9% Year on Year

The short version: Osaka detached-house asking prices hit a record, but discount the monthly jump

On November 9, 2026, the private research firm Tokyo Kantei published its October 2026 average prices for resale and newly built wooden detached houses ^[1][3]. The headline: the average asking price for resale detached houses in Osaka Prefecture was ¥36.82 million, up 13.0% from the previous month and the highest since the series began. Compared with a year earlier, however, it was up only 6.9% ^[2]. A large monthly rise paired with a much smaller annual rise suggests that a good part of this month's jump reflects a change in the mix of listings, not similar homes becoming more than 10% more expensive in a single month.

First, the scope of the data. Both series cover detached houses on land of 100 to 300 square meters, within a 30-minute walk or 20-minute bus ride of the nearest station, of wooden construction, with both land and building held as freehold. Prices are seller asking prices, and the resale series also includes homes originally built to order ^[2][4]. These are not transaction prices.

Resale detached houses: records in both Kinki and Osaka Prefecture

• The Kinki region (Osaka, Kyoto, Hyogo, Shiga, Nara and Wakayama) averaged ¥31.76 million, up 11.8% month on month and the highest since the series began in April 2014; year on year it rose 2.2% ^[2].
• Osaka Prefecture averaged ¥36.82 million, up 13.0% month on month and 6.9% year on year, with an average land area of 144.8 square meters, building area of 112.9 square meters and building age of 25.6 years ^[2].
• Hyogo Prefecture averaged ¥30.77 million, up 11.1% month on month and 4.9% year on year ^[2].
• Kyoto Prefecture averaged ¥43.12 million, up 9.1% month on month and back above ¥40 million for the first time in four months; year on year it fell 2.2%, and the average building age was 37.4 years ^[2].

For comparison, resale detached houses in the Tokyo metropolitan area averaged ¥41.87 million in October, down 6.5% month on month ^[1]. Tokyo Kantei summarized Kinki as a month in which the major prefectures all rose by around 10% ^[2].

Osaka City: up 27.4% in a month, driven by high-priced listings

Among major cities, Osaka City moved the most. The average resale detached-house asking price was ¥74.04 million, up 27.4% month on month and 34.0% year on year, a new record. Tokyo Kantei noted that Osaka City saw high-priced listings in Tennoji Ward ^[2]. In the previous month (September), the Osaka City average was ¥58.12 million ^[2].

New detached houses show the same pattern. Osaka City averaged ¥63.31 million, up 18.7% month on month and 27.2% year on year, again with high-priced listings cited in areas such as Tennoji Ward. But the October sample of new detached houses in Osaka City was just 18 homes ^[4]. With so few listings, a handful of expensive homes can push the average up sharply.

New detached houses: much gentler increases

• New detached houses in Kinki averaged ¥39.97 million, up 4.5% month on month, the first rise in three months, and up 5.1% year on year ^[4].
• Osaka Prefecture averaged ¥45.07 million, up 5.5% month on month and 8.4% year on year; the month's sample was 177 homes, with an average land area of 124.4 square meters and building area of 101.5 square meters ^[4].

The same firm's condominium data offer a useful contrast. In September, the 70-square-meter-equivalent asking price for resale condominiums in Kinki was ¥36.93 million, up 1.5% month on month and the 16th consecutive monthly rise; Osaka Prefecture was ¥45.06 million, up 1.4% ^[5]. Condominium figures move far more smoothly from month to month because the samples are larger and the units more standardized.

What it means for buyers

First, a monthly average does not mean "the house you are looking at went up." Detached houses vary widely in location, size and age, and the figures are asking prices rather than sale prices. The gap between Osaka Prefecture's 13.0% monthly rise and 6.9% annual rise, and the sample of only 18 new homes in Osaka City ^[2][4], are both reminders to judge the trend by year-on-year changes and the direction over several months, rather than being alarmed or rushed by a single month's number.

Second, Osaka detached-house prices are still trending up overall. Setting the single month aside, resale detached houses in Osaka Prefecture rose 6.9% year on year and new ones rose 8.4%, which points to a market that remains firm ^[2][4]. For households with a fixed budget, the gap between what the same money buys inside Osaka City and in the suburbs may keep widening.

Third, compare individual homes like for like. When you look at the price of a particular house, recent listings and sales near the same station with similar land area and building age are a better benchmark than the prefecture-wide average. Also factor in repair costs that come with age, as well as road frontage and rebuilding conditions. In Kyoto Prefecture this month, the average building age rose yet the average price still went up, a typical example of how the mix of listings moves an average ^[2].

Summary

October's data show resale detached-house asking prices in Osaka Prefecture reaching a record, with Osaka City rising sharply on the back of high-priced listings in areas such as Tennoji Ward. Yet the smaller year-on-year rise and the small sample sizes are reasons to discount the single-month jump.
