• Yes, the most surveilled cities in the world are in China

  Toronto has a lot more CCTV cameras than I would have thought.

  According to this (2022?) data from Comparitech, there is estimated to be about 19,236 cameras installed around the Greater Toronto Area. With a population of around 6.31 million people, this translates into a per capita rate of 3.05 (CCTV cameras per 1,000 people). What this means is that there is almost surely footage of me enjoying a late-night shawarma sandwich after the bar somewhere on the streets of Toronto.

  In some ways, this is a high number of cameras. Tokyo, which is usually considered to be the largest metro area in the world with nearly 40 million people, only has 1.06 cameras per 1,000 people. Dhaka is 0.71. Sao Paulo is 1.04. Osaka is 1.57. And Montreal is 1.03. Though to be totally fair here, Rio de Janeiro is up at 3.34 (and it may be the most dangerous city mentioned in this post). Paris is 4.04. New York is 6.87. Los Angeles is 8.77. And London is 13.35.

  But where things get really exciting is in authoritarian places. Moscow is estimated to have 16.85 CCTV cameras per 1,000 people. And in China as a whole, there is estimated to be roughly 540 million cameras scattered around its cities, which works out to an average of 372.8 cameras for every 1,000 people. For a city like Shanghai, this crudely equals something like 10.6 million cameras.

  It turns out that surveillance is pretty important for things other than shawarma-eating videos:

  Vyborov wasn’t arrested that day, but the police informed him that he was under surveillance through Sfera, one of Moscow’s face recognition systems, for participating in unsanctioned rallies. Considered one of the most efficient surveillance systems, Sfera led to the detention of 141 people last year. “Facial recognition, and video cameras in general in a totalitarian state, are an absolute evil,” Vyborov says.

  Here’s the other thing. Safety is usually touted as the reason to have lots of cameras. But Comparitech’s data suggests that there’s an almost non-existent correlation between lots of cameras and lower crime. I mean, just look at Tokyo. It is basically the model megacity, and its per capita camera rate is only 1.06. The real utility, it would seem, is using cameras and face recognition software to restrict personal freedoms.

• The Tokyo Toilet – Part 2

  You can tell a lot about a place by the quality of its public toilets. I don’t know about you, but if I’m at a restaurant and the toilets are filthy, I automatically assume that the kitchen is at least as filthy.

  And so what does it say about Japan that it decided to hire the country’s leading architects to design 17 new public toilets in Tokyo?

  I first wrote about “The Tokyo Toilet” back in the summer of 2021. But now that the majority of them have been constructed, I figured it was time to revisit the project.

  The two toilets designed by Shigeru Ban are particularly noteworthy in that they are clear glass boxes that become automatically opaque when in use. This was done so you can see if there’s anyone lurking inside.

  I also love this one by Kazoo Sato.

  But of course, all of them are remarkable and all of them are probably better than the general level of public architecture that you’ll find in most other cities.

• Japan pays people to leave Tokyo

  We have spoken over the years — here, here, and here — about the centralizing and decentralizing forces that play out within our cities. Agglomeration economies, for example, are a centralizing force. There are real economic benefits to people and firms clustering together in cities.

  However, there are also many decentralizing forces. Traffic congestion is one. And of course, the pandemic also proved to be a powerful one for many cities.

  But the fact that we even have cities in the first place should tell you that the centralizing forces do tend to win out over the decentralizing ones. And a perfect example of this is Tokyo. Usually considered to be the largest metropolitan area in the world, Tokyo has about the population of Canada in one city region.

  And here, the centralizing forces are so great — even for families — that the government actually pays people to relocate to places outside of Tokyo’s 23 wards (and its immediately surrounding areas). Previously the maximum figure was ¥300,000 per child (~CA$3,056), but this has now been increased to ¥1 million per child (~CA$10,188).

  A key driver of this is surely Japan’s demographic problem (namely a shrinking and aging population base). But it doesn’t change the fact that lots of people appear drawn to the world’s largest city.

• Distributed Japanese capsules

  

  Japanese Metabolism was a post-war architectural movement that was based around the idea that cities and buildings should be able to grow and transform just like other organisms. There are other elements to the movement, but this was at its core. And perhaps the best example of the Metabolism movement was the Nakagin Capsule Tower in Tokyo (pictured above).

  Constructed between 1970 and 1972, the 13-storey tower consisted of two structural elements and 140 self-contained / prefabricated capsules that were hung off the building’s cores.

  The original intent was that these capsules could be removed and replaced over time and that the building could evolve just like any other organism might. But that never really happened and, coming on the end, only about 30 of the 140 capsules were apparently still being lived in, with the others being used for various purposes, such as storage, or not at all.

  And so after a whole lot of debate, the building was disassembled earlier this year, which isn’t quite the same as a straight demolition. The pods were removed and then the core came down.

  But a number of the pods have been salvaged. The architect’s family took 4 pods and created an Airbnb retreat a few hours outside of Tokyo. And a longtime resident in the building decided to quit his job, acquire 23 of the capsules, and dedicate his life to now getting these things into museums and other commercial settings.

  I don’t feel like it’s my place to comment on whether disassembling the tower was a good idea or not. But I do think there’s something poetic about an icon of Metabolism having its capsules removed, restored, and then sprinkled around various places. Wasn’t that always kind of the intent?

• Swimming in the Seine

  There is an ongoing debate about the value of cities hosting the Olympic Games. And that’s because this is usually how it works: You, the host, spend a lot of money (Tokyo 2021 was over $25 billion), it feels really good during the games while the world is watching you on TV, and then everyone leaves and you have a big bill to pay.

  As I understand it, this has generally been the case for almost all of the games. One rare exception is Los Angeles in 1984, which supposedly managed to make over $230 million from hosting. In pretty much every other case, the rough value was, at least in theory, things like exposure, ego, and hopefully a bunch of assets that will remain useful to other people once the games are done.

  But as I have argued a few times before, perhaps the most important hard-to-quantify benefit is this: Hosting the Olympics creates an immutable city-building deadline. Because, what could be worse than not being ready when your global guests show up?

  A perfect example of this is what Paris is now trying to do with the Seine ahead of the 2024 Olympics. The goal is to clean up the Seine so that it’s actually safe enough for the athletes to compete in it. That would obviously be really cool for the games, but it would also be a wonderful legacy for Paris.

  Would Paris still be doing this if it weren’t hosting the games? Perhaps. Paris has a habit of doing some obviously good things. But I bet it wouldn’t be moving nearly as quickly.

• [Book] Emergent Tokyo — Designing the Spontaneous City

  

  I just ordered a copy of this book. So I haven’t read it yet. But I did just read this Q&A with the authors (and it clearly piqued interested). The central idea is that Tokyo — which is a massive city that is famous for somehow being both massive and exceedingly livable — is the product of something that the authors refer to as emergent urbanism.

  What they mean by this is that Tokyo’s order, functionality, and livability is actually largely the result of emergent bottom-up actions, rather than top-down central planning. This isn’t to say that some top-down planning isn’t required for things like parks and transit. You still need some of that. But this is to say that Tokyo’s approach to urbanism is very different from what you’ll find in cities likes Paris and many others.

  Here’s an example of what I’m talking about (taken from the above Q&A):

  This is going to sound wild to anyone who lives in the US, but for any two-story rowhouse in Tokyo, the owner can by right operate a bar, a restaurant, a boutique, a small workshop on the ground floor — even in the most residential zoned sections of the city. That means you have an incredible supply of potential microspaces. Any elderly homeowner could decide to rent out the bottom floor of their place to some young kid who wants to start a coffee shop, for example. When you look at what we call yokocho alleyways — charming, dingy alleyways that grew out of the black markets post-World War II, which are some of the the most iconic and beloved sections of the city now — it’s all of these tiny little bars and restaurants just crammed into every available space.

  What’s fascinating about all of this is that we’re talking about a kind of self-organizing urbanism. One that goes against everything that traditional city planning stands for. Using the above example, instead of saying that retail should go here, bars should go here, and residences should go only over here, Tokyo is basically saying you can do whatever you’d like.

  If you’d like to open a tiny 4-seater bar that only serves Long Island iced teas to people wearing cosplay outfits on neon pink plastic chairs, you are free to do that. Oh, and by the way, we’re also going to make it a lot easier and cheaper for you to get a liquor license. This might sound chaotic, but it works for Tokyo. And it’s evidence that maybe a lot of our cities would be better off if only we let them be what they want to be.

• What might Toronto learn from this infill rental project in Tokyo

  This is a lovely little infill rental project in Tokyo by ETHNOS (architect) for Real Partners (developer):

  The building is 4 storeys plus a rooftop terrace. From the plans, it looks like there are 8 units, all of which are two-storey suites.

  

  The A and B suites are accessible from the ground floor. For the A suites, you enter at grade, and then go down into the first basement level. And for the B suites, you enter at grade and then go up to your second level. One of the entrances (suite B-3) is via an exterior walkway.

  The middle of the ground floor is the lobby entrance and there’s a single elevator that services the second and third floors (it then drops off for the fourth floor). On the second level is a co-working space, and so the upper C suites (these sound fancy) are all accessible from the third floor.

  The fourth floor and fifth floor terraces are all accessible from within the C suites, which means that the only real common area corridors in this building are on the third level. And it looks like they wanted this particular corridor to have a view to the street, because they could have easily reduced it even further to increase the building’s overall efficiency.

  

  What is also interesting to look at this building’s dimensions. Based on the above section, the floor-to-floor heights are 2500mm, which is low compared to the 2950/3000mm that is typically used here in Toronto for new reinforced concrete builds.

  In terms of the overall building, it is only about 10m deep and it is less than 10m tall if you exclude the stair popups on the rooftop terraces. For context here, our Junction House lot is about 30m deep and the build is about 30m tall, so actually a similar kind of box proportion.

  But let’s scan more of Toronto.

  If you move away from designated “Avenues” (which is where Junction House sits) and look at some of our other major streets (which is something the City of Toronto is in fact doing), you can sometimes/oftentimes find even deeper lots.

  Below is a random area that I quickly panned too on Dufferin Street — these single-family house lots are around 36m deep:

  

  Now obviously Toronto is not Tokyo and Tokyo is not Toronto. But my point with all of this was to demonstrate just how much space we actually have within our existing boundaries, should we ever feel the need to increase our overall housing supply.

  As I have argued many times before, I think one of the greatest opportunities to quickly do this sits along our majors streets.

• Do the best cities have a lot of immigrants?

  The best cities have a lot of immigrants.

  — Brandon Donnelly (@donnelly_b) February 13, 2022

  I tweeted this out last night while watching old reruns of Anthony Bourdain’s Parts Unknown series. This was a great show. If I were to give everything up and become a YouTuber, this is the kind of travel and food channel I would want to make, except that I would naturally have to add in some equal parts around architecture, planning, and real estate.

  The responses to my tweet were of course mixed. Some people agreed and some people didn’t. And a few people provided examples of great cities that aren’t particularly known for their openness to new entrants — places like Tokyo. This kind of response is not at all surprising given how divisive this topic has always been throughout history.

  But here’s what I was thinking:

  1/ There are some obvious current case studies. Consider places like Toronto and Miami, where foreign born residents now make up the majority of the population. These are two fast growing and dynamic cities that wouldn’t be anywhere near as interesting without their immigrant populations. Certainly the food wouldn’t be as good.

  2/ Many of the most beautiful cultures in the world are the result of different cultures coming together. Brazil is one example that comes to mind. Throughout history they have been one of the largest recipients of immigrants in the western hemisphere. Sadly, Brazil was also the last country in the western world to abolish slavery.

  3/ Rome and Tokyo were cited (in the comments) as two great cities that frankly aren’t all that diverse. According to Wikipedia, less than 10% of Rome’s population is non-Italian. But Rome, while nice, is provincial these days. And Tokyo, while awesome, has a bit of a demographic problem.

  4/ Even if you think a place doesn’t have a lot of immigrants and maybe isn’t all that diverse, it is still probably the result of diverse cultures coming together at multiple points throughout history. Maybe because of immigration. Or maybe because of something bad like war. Think of the Moors from northern Africa who crossed the Strait of Gibraltar and conquered the Iberian Peninsula.

  5/ An openness to new people could signal and probably does signal an openness to other things. And since we are living in a world that thrives on innovation and new ideas, being open strikes me as being a fairly good and useful characteristic to have.

  6/ Lastly, I come from a family of immigrants. I self-identify as being entirely Canadian. But I had to come from somewhere (multiple places, in fact). And so it strikes me as being odd and entirely selfish to want to block the flow of people now that I’m here and established.

  What are your thoughts?

• Slime mold may be better than us at transportation planning

  So slime mold, which is a fungus-like single-celled organism, has a tendency to build highly optimized networks across its food sources. In other words, if you scattered a bunch of food on a surface and then dropped in some slime mold, it would naturally create an interconnected web of linked veins across this surface. And this web would be based on the shortest and most efficient paths of travel between the various food sources.

  I am mentioning this odd factoid because ten years ago researchers in Tokyo used this naturally occurring phenomenon for the purposes of trying to improve transportation planning. What they did was map out greater Tokyo. They then placed oat flakes (i.e. food) in spots that correspond to the various cities and urban centers that surround the city. Alongside this, they blocked off the areas where transportation networks do not typically run, such as through mountains and into the water. They then dropped in some slime mold, wet the surface, and watched it grow.

  

  What they found was that the resulting network was remarkably similar to Tokyo’s actual rail network. The slime mold had found the most efficient routes, eliminated redundancies, and generally discovered the optimal way in which to connect its food sources. And if you think about it, this is basically what transit networks are supposed to do. They should connect clusters of people in the most efficient way possible.

  It has been a decade since this slime mold transportation discovery was first publicized, and it would seem that it hasn’t really caught on as an invaluable planning tool. So I’m going to go out on a limb and suggest that we should take out a map of every major city in the world, plot its population centers, drop down some oat flakes, and then let slime mold tell us all the ways in which we are screwing up and over-politicizing our transportation planning efforts.

  Thank you to Angus Knowles for making me aware of this study. Angus writes an occasional newsletter about cities and housing, over here.

• Largest cities in the world from 100 to 2015 CE

  I just discovered this set of maps (via Brian Potter) looking at the largest cities in the world from 100 CE all the way through to today (well 2015 CE). Here are what the two bookends of this map series look like:

  

  

  It is an interesting reminder of just how centralized the world was around the Mediterranean and parts of Asia, and also how nothing is guaranteed. As recent as 1900, cities like Manchester and Philadelphia were among the top 10 largest cities. Today they aren’t even close.

  For the full map collection, click here.

  UPDATE: The data behind these maps has been called into question. Look out for a follow-up post.
