Choose an area, buy the land, and build a home. So far, we have followed the process of building a home in Ashiya, but there is one final—and important—perspective to consider: how does that home perform as an “asset”? While it is, of course, a place to live, a home in Ashiya is also the largest asset many people will ever own. This time, we take a look at Ashiya real estate from the perspective of owning and selling.
First, the basics: Land prices in Ashiya continue to rise
Ashiya’s strength as an asset is clearly reflected in the numbers. In 2026, Ashiya’s officially published land prices across all uses rose 4.8% year-on-year, marking the 15th consecutive annual increase. Even in residential areas alone, prices averaged approximately ¥1.3 million per tsubo, up 3.96%, while the average annual growth rate over the past decade has been about 3.7%—a steady upward trend.
Of course, prices will not rise forever. They reached approximately ¥1.99 million per tsubo in 1995 during the bubble era, before falling to around ¥820,000 per tsubo in 2005. Even so, over the long term, Ashiya’s status as one of Japan’s premier residential areas has sustained strong demand, making it a place where property values tend to hold up well.
A guide to actual transaction prices
So how much are properties actually selling for? According to data from various companies, the median price of a pre-owned condominium in Ashiya is generally in the mid-¥30 million range, assuming a unit near a station with roughly 21 tsubo of floor space. Prices have risen by approximately 50% over the past decade. The momentum has continued recently as well, with sale prices for pre-owned condominiums up more than 13% year-on-year in the first half of 2026.
However, these figures are only a starting point. Even among condominiums, prices per tsubo rise sharply in popular areas near stations, such as Oharacho. For detached homes and hillside estates, prices can range widely—from tens of millions to hundreds of millions of yen. There is one key principle to remember here: the single biggest factor affecting a condominium’s asset value is its distance from the station. Even within the prestigious Ashiya market, properties closer to a station remain less likely to lose value.
But selling a high-end home in Ashiya is a different matter
This is where we get to the issue that is unique to Ashiya. In the luxury market, looking at an average-price table and assuming that your home will sell for a similar amount can be misleading.
Reason 1: The pool of buyers is limited. There are not many people who can purchase a home worth several hundred million yen on something close to an all-cash basis. With fewer potential buyers, a sale may take longer, and the final price may differ significantly from expectations. Average figures on market-price tables are not particularly reliable in this segment.
Reason 2: The best properties rarely reach the open market. Grand residences in Rokurokusocho and similar neighborhoods are seldom listed for sale in the first place. Many are traded discreetly through networks of affluent buyers or locally established real estate companies before ever appearing on public property portals or REINS. In this price range, the properties visible to the public are far from the whole market.
Reason 3: That means the sale price depends on whom you entrust with the property. Standardized appraisals from major companies can only price a property as an extension of general market data. By contrast, the ability to articulate qualities that do not appear in market-price tables—such as the views, architectural quality, and rarity of the land—and present them to the right buyers depends heavily on the expertise of an agent experienced in Ashiya’s luxury market. As mentioned in our guide to Ashiya’s neighborhoods, “Rokurokuso cannot be measured by price per tsubo.” That becomes especially important when it is time to sell.
Because it is an asset, consider both your “exit strategy” and succession
There is another consideration unique to high-value assets. Because homes in Ashiya can be worth so much, taxes on the profits from a sale—and the burden of eventually passing the property on to the next generation—can also be substantial.
That is why the people who ultimately benefit most are those who consider their exit strategy from the time they buy or build: when and how they might someday sell the home—or leave it to someone else. A home in Ashiya is both a place to live and an asset to manage over the long term. Whether you can see it from both perspectives may ultimately determine how much value it brings to your life.
