We’ve written extensively about Tokyo’s current condo boom without really addressing what it will lead to in the long run. Most commentators seem to expect a burst bubble, like the one that happened in the early 90s following a similar over-valuation of properties in the late 80s. However, there is an important difference in that the current Tokyo bubble is being pumped up by rich people. The average price of a new condo in the capital has exceeded ¥100 million. In the late 80s, the bubble was caused by everyone, since the huge boomer cohort had secured its lifetime employment and banks were willing to lend them money. Even though housing interest rates are low in Japan compared to the bubble era, younger families with average incomes who still insist on buying new condos are finding it difficult to find anything they can afford in the 23 wards, according to local media.

A recent video on the YouTube real estate channel Rakumachi put the present bubble in perspective, especially in terms of what it holds for the future. According to Tomohiro Makino, a “real estate producer” whose career started in the 80s, people who say the Tokyo condo market is “over-heated” need to look at classic supply-and-demand. “Over-heated” suggests that the market will eventually cool, but since this particular bubble is being caused by rich people and institutional or business investors, it isn’t that simple. Scarcity is one of the factors fueling the over-heated prices: the number of new condos on sale in recent years is one-third the number that were on sale in a given year two decades ago. Much of the reason for this scarcity is the high cost of building materials and lack of labor. Building a condominium is much more time- and capital-intensive than it used to be, so developers have scaled down. And with prices so high, buyers trend toward people who benefit from certain financial realities, such as foreign investors who can exploit the historically cheap yen. Even rich elderly Japanese who don’t necessarily need a new place to live are buying high-end condos in Tokyo as hedges against taxes their heirs will have to pay when they die. So they invest their cash in real estate, which can lower the inheritance tax burden by as much as 70 percent. Those who do buy new Tokyo condos for living purposes tend to be so-called power couples—married people whose combined incomes exceed ¥15 million a year. 

So the high condo prices are essentially being maintained by a small group of people. Nomura Securities says the number of “very wealthy” households in Japan, meaning they are worth more than ¥500 million each, is around 90,000, for combined assets (not counting debt) of ¥105 trillion. Merely “wealthy” households (¥100-¥500 million) number around 1.4 million with ¥259 trillion in assets; “less wealthy” (¥50-¥100 million) number 3.3 million with ¥258 trillion; upper middle class (¥30-¥50 million) number 7.2 million with ¥332 trillion; and the vast middle class (less than ¥30 million), numbering 42 million, is worth ¥678 trillion. Though the top two tiers account for a bit more than 2 million households, the amount of assets they control is considerable. Much has been made of the global income gap in recent years, and Makino says the top 1 percent in Japan has seen its wealth increase by 80 percent since 2013, when Abenomics. The investment market was flooded with easy money, but average households received no comparable benefit from the policy. Makino says that its effect on real estate has led to the over-heated condo market, putting Tokyo real estate out of the reach of the middle class. Developers don’t even think about this group of consumers, because they know that even if every condo they build is luxury-class, they can still sell them. Consequently, they don’t have to build that many in order to make as much money as they used to make when they sold to everyone. The average price of a new condo in the 23 wards as recently as 2015 was ¥60 million. Last year it was ¥115 million. And due to the lag in construction costs, prices will continue to go up for the near future. 

And it’s construction costs that are the main concern for developers, since right now they account for 70 percent of the cost of a condo, the other 30 percent being land. This aspect is very significant, because while land prices vary greatly depending on location, construction costs do not. It costs almost the same to build a condo in the suburbs as it does to build one in the center of Tokyo, so most developers are putting as much of their money and resources as they can into the city. Even mid-sized developers that tend to do all their work in the suburbs are foregoing new construction to invest in new condos in Tokyo by borrowing money to buy them from major developers. Then they quickly resell them to make money. The most prevalent example of this kind of practice in the news right now is the Harumi Flag complex on the waterfront, which was built as the Tokyo 2020 Olympic athletes village and then sold or rented out afterwards. A substantial number of the condos remain empty because they’ve been bought by corporations, including developers, as investments, thus pushing the price of individual units up. According to Makino, some companies have bought from 10 to 20 units in Harumi Flag.

Makino sees this trend continuing as long as interest rates remain low, since most investors don’t use their own money to buy real estate. Once rates start to rise, he says, the market will cool as investors pull out. Now that the era of the “negative interest rate” has ended in Japan, he thinks that such a change is on the horizon, even if many experts believe the Bank of Japan won’t increase interest rates due to the amount of government bonds it has. But the BOJ doesn’t control interest rates. Other factors, including environmental disasters, international politics, even rumors, will always come into play, and once they do “the party will be over,” meaning even foreign investors will bail regardless of the exchange rate. This could prove to be a huge shock to the system. After all, young Japanese adults today know nothing about interest, having been born without any experience of bank deposits earning interest. It’s unrealistic to think that this kind of environment will persist indefinitely, but until it does change it’s also unrealistic to thing that average Japanese people will step in when wealthy investors drop out. It’s just too risky for the average household to buy a condo in Tokyo now or in the near future.

If Makino were to give advice to potential middle class homeowners who want to live in Tokyo, it would be to wait, probably until 2030, by which time he says the “market will surely change.” Not only will prices for condos, used and new, go down, but so likely will rents. And his reasons for thinking so are grounded in an unavoidable truth. Households headed by people over 65 in the Tokyo metropolitan area now number 9 million, with half of those headed by people over 75. That number will steadily increase. After 2025 all the 1.5 million boomers living in the metro area will be over 75, and while lifespans are also increasing, it won’t be long before this cohort starts dying out in record numbers, which means their property will either be left to heirs or abandoned, if it hadn’t already been sold. These people came to the metro area in their youth to work, and they bought homes. But their children, now middle aged, mostly own their own homes, too, and so won’t need their parents’, which means they’ll sell it or do something worse (pretend to ignore it?), but in any case there will be a lot of empty homes on the market. This, as Makino points out, is the heart of the akiya problem, which will only intensify by the end of the decade, throwing the real estate market, including Tokyo’s, into turmoil. Oversupply will become a chronic issue unless the construction industry and the authorities change their tune with regard to building new residences, which is pretty much all they think about now. 

But that means the possibilities for homeownership will shift 180 degrees from what they are right now and Generation Z will be able to buy homes with cash. Of course, there will be exceptions. Neighborhoods like Roppongi will always be available only to the well-off, but Tokyo could again be affordable to younger families. In a different Rakumachi video, Makino talks briefly about renting versus owning, and admits that people often mistake him for being “pro-rental” simply because he tends to dwell on the risks of ownership. Once you buy a house in Japan, you’re stuck with it, he points out, but if you rent you can always move. His main problem with renting has nothing to do with the concept but with the way it’s looked down upon, especially by the government, whose policy of pushing home ownership is so monolithic that they have completely ignored the rights of tenants and the matter of affordable rental housing. But he thinks that after 2030, the market itself will make rental properties more favorable to renters to the point that it may end up being more financially wise to rent than to own, since the surplus housing that is constantly accummulating will make it more and more difficult to sell one’s home, much less make any money from it, and that includes homes in Tokyo. What’s the difference between renting and owning if the house you own has no resale value or equity? The only thing you can say is that if you own you don’t have to worry about being kicked out.

But your heirs will likely be stuck with the property when you die. As mentioned above, when everyone owns their own home and finds it difficult to sell, inheriting a home can be a lot of trouble, and Makino urges people to think about this carefully when their parents become old, since one of the biggest problems with inheritances is that the designated heirs don’t know what to expect until they receive that inheritance. By that time, says Makino, “it’s too late.” Makino relates the story of his own father, who was born during the Taisho Era “but could use a computer,” which he used to list all of his assets before he died so that his children could better be prepared to handle those assets. In that regard, he advises people to get rid of “unneeded real estate” as soon as possible, which will become more of a chore in the future. Already, there are suburbs of Tokyo where it is close to impossible to sell homes, including condos located close to train stations. Being able to just sell a home in such locations, even for a few million yen, will become more a matter of luck than anything else. His only two pieces of advice are asking a neighbor if they want to buy the land cheap in order to expand their property; and donating the property to the local government. But with the latter, such donations come with very strict conditions, including in many cases a management fee for a fixed period of time, usually ten years, that can be very costly. Again, if you’re in Tokyo, you can probably still sell your property (though not necessarily for more than what you bought it for), but elsewhere it will be a brave new world of every seller for themself, and may the best property owner win.
