We have spoken many times before about the fact that Japan is built around rail-oriented urbanism. But if you have the time right now, I'm going to suggest that you read this longish article by Matthew Bornholt & Benedict Springbett called "Why Japan has such good railways," because nowhere else in the developed world uses rail for passenger kilometres more than Japan, and they explain why.
One common hypothesis, which is mentioned in the article, is that it's largely cultural. The Japanese are rule-abiding collectivists who are more willing to take public transit compared to us selfish and individualistic North Americans. But this doesn't seem right. In fact, one could argue that the Japanese solution is actually more free-market oriented.
The Japanese rail model seems to work so well because (1) most of the network is private, (2) liberal land-use policies have allowed Japan's urban centres to develop enough density to properly support the use of rail, and (3) the rail operators make money in a bunch of other ways beyond rail. They're typically also in the business of real estate.
Here's a quote from the article by the president of the Tokyu Group that I absolutely love:
I think that though we are a railway company, we consider ourselves a city-shaping company. In Europe for instance, railway companies simply connect cities through their terminals. That is a pretty normal way of operating in this industry, whereas what we do is completely different: we create cities and then, as a utility facility, we add the stations and the railways to connect them one with another.
This is a fundamentally different model that allows rail companies to capture some of the value that they inherently create. To use the example of Toronto's Eglinton Crosstown line, it's the difference between saying, "I'm going to build a rail line and then, presumably, other stuff will happen," and, "I'm going to develop this midtown corridor and then I'm going to run rail underneath it to maximize value creation."
If Japan can do it, so can we. Ironically, a big part of it means easing land-use controls and allowing transit-oriented development to simply be what it wants to be — dense and proximate to rail.

Where Americans flew in 2025
The top United Airlines international destinations by US state
Whether you live in North Dakota or Texas, there's a reasonable chance that when you travel internationally, you enjoy going to Cancun. Or perhaps you fly into Cancun and then go to a neighboring town like Tulum. United Airlines just released the following map showing the most-booked international destinations from every state for passengers traveling on United Airlines between January and October 2025. The top three destinations are London, Cancun, and Tokyo:
First, it's important to keep in mind that this data only includes people flying on United; it doesn't capture all international air travel. Second, maps like this are necessarily going to be influenced by an airline's biggest hubs. In the case of United, its hub-and-spoke model relies on major airports and routes like San Francisco-Tokyo and Newark-Heathrow.
Still, specific destinations appear on this map for a reason. Cancun is the number one "vacation" airport for Americans, which is an incredible success story, because it wasn't a place until the 1970s. Prior to Cancun, Acapulco was Mexico's top resort destination, but it was becoming constrained, and the government needed a replacement conduit for extracting US dollars from the American middle class. So, they developed Cancun.
The popularity of Tokyo is likely partly a result of a weaker yen, in addition to being an important Asian hub and an incredible place to visit. According to the Japan National Tourism Organization (JNTO), over 2.7 million Americans visited the country in 2024 — a 33% year-over-year increase and a 58% increase compared to 2019.
The country also saw 3.7 million international visitors in January 2025, which is the highest ever for a single month. Countries like the US and Canada also set all-time records for January arrivals. Part of this, I'm sure, has to do with Japan's legendary "Japow." I was part of this year's cohort, and I've never seen so much snow as I did on the island of Hokkaido.
There are also very specific one-off relationships that appear on United's map. The number one destination for the state of Arizona is, for example, Taipei. And this is being driven by a semiconductor boom, specifically Taiwan Semiconductor Manufacturing Company's direct investment in the state. At the time, it was heralded as "the largest foreign direct investment in a greenfield project in American history."
So, there's a lot that can be gleaned from a map like this. If we were to zoom out and look at all international air travel, we would likely see some reordering. I suspect Paris would jump ahead of airports like Vancouver, given its hub status for other airlines. But it's unlikely you'd see a completely different list. Americans fly east to London, south to Cancun, west to Tokyo, and north to Toronto. These are the primary hub airports.
It's fun to examine projects that I could never underwrite or build in Toronto. Here's another one from Tokyo — a 10-storey, single-stair apartment building on a busy street, next to a metro station.
The site itself is only 59.49 m2 (~640 ft2), and the building footprint is 47.97 m2 (~516 sf), for a total of 388.28 m2 (~4,179 ft2). There's retail on the first and second floors, one home per floor on levels 3 through 8, and then a two-storey home on levels 9 and 10. All of this is serviced by a single elevator, and a single open-air egress stair off the back.
The building itself uses a simple structural system involving 6 columns (which you can see evenly placed on the plans). According to the architect's notes, they started with a simple 4-column design, but apparently the columns were too large and compromised the suite layouts.
Tokyo is a unique city and this kind of housing wouldn't work everywhere. But there's a universal lesson here: removing barriers and allowing small infill projects is a good thing for cities. Until these projects are feasible, we won't know exactly what the market actually wants and could support.
