Reece Martin is perhaps best known for his YouTube channel focused on transit. He has over 330,000 subscribers, and I have mentioned him a few times over the years on this blog. But he has since retired from YouTube and he now has a new blog called "Next Toronto," which you should all subscribe to. I just did that today.
In his latest post, he makes "the case for a 24-hour Toronto" and compares our city to various other global cities around the world including New York and Tokyo. This post really resonates with me and I agree with his view that there's something quintessentially urban about things being open all the time, or at the very least open late.
According to ChatGPT, Toronto is a "semi 24-hour city." Its deficiencies:

Here's how I generally think about it.
Step 1 is reasonable daytime hours. As a North American, I still find it frustrating how some/many restaurants in Europe close between lunch and dinner. Call me spoiled, but what if I got held up at work and couldn't eat during the generally accepted time? Or if I went to the gym in the morning and now I suddenly have a dire caloric deficit?
Step 2 is staying open kind of late, including on Sundays. A few weeks ago I was driving around the suburbs of Toronto — on a Sunday — and I decided to take advantage of this rare occurrence to stop in at what's called an enclosed shopping mall. So I got all the way there, pulled confidently on one of the front doors, and then realized it had closed 2 hours ago.
Step 3 is the rarified big leagues; you're a "24-hour city." Reece gives the example of Apple's Fifth Avenue store, which, in case you forgot, never closes. I don't typically shop for consumer electronics at 3AM, but I might. And there's something oddly comforting about knowing I could. This isn't possible in all cities, but it is in New York. That says something.
I have a new not-so-serious goal. I say not-so-serious because I'm busy with lots of other things and who knows if/when I'll actually get around to this. So let's just say that this goal is based on a strong interest. I would like to visit the 10 largest urban areas in the world.
I was careful to say urban areas, because largest cities can be misleading. City proper boundaries are an arbitrary measure. What matters more are the built up areas.
I have already been to a handful of them, namely the ones centered around Tokyo, Dhaka, and Mexico City. But there are more on the list that I haven't been to.
There are, however, two immediate challenges with setting a not-so-serious goal like this one. The first is that it's not easy to come up with a definitive list of the largest urban areas. It's nuanced and, for some cities, population estimates are very much rough estimates.
The second is that population figures are constantly changing. So by the time I get around to this, many of the largest cities might be in Africa (current forecast for this century) and I may be checking off the wrong list.
But let's not let perfect be the enemy of good. Here's what I came up with. And by "what I came up with," I mean that I asked ChatGPT its opinion. This is the list I got:

Then I asked the question in a slightly different way and got this list:

Then I asked it to tell me its definition of metropolitan area vs. urban agglomeration:

Finally, I asked it why Lagos, Nigeria was not on the list. Current estimates place this urban region at more than 20 million people (which would place it ahead of New York in the first list), but I don't think anyone really knows for sure. Whatever the current number, it is widely understood to be one of the fastest growing city regions in the world. This is how ChatGPT responded:

I'm a little torn because high on my list of cities to visit are São Paulo and Seoul. And they don't seem to be finding themselves on the same list. I'm also very curious to see Lagos, and I have a suspicion that it's much larger than official estimates. Regardless, there are some clearly big cities to check off. India and China would be good places to start. So I better get to work. Or not. Since this is a not-so-serious goal.

In my recent post about "takeaways from Japan" I spoke about a willingness to experiment and be playful with the built environment. I said that quite often people design homes around what they want, as opposed to what they think might broadly appeal to the market. So today, let's look at an example. Below is a site on the outskirts of Tokyo, about an hour from the center of the city. The architect — Kamakura Studio — describes it as being situated in a "new town" where about 75% of the residents have moved in within the past decade. And like Japan as a whole, problems of aging and population decline are expected in the future.

Using Google Maps to get rough dimensions, the site looks to be somewhere around 8m wide by 11m deep. So this is not a huge site compared to what you might find in the suburbs of other cities, but it's certainly a very workable set of dimensions. Also noteworthy is the fact that the area has no sidewalks. This is common throughout Tokyo. Ordinarily, this would imply a suburban mental model. But in practice, Tokyo's streets actually feel very pedestrian-friendly. And that's because they tend to be narrow and the entire city is oriented mostly around rail.
What was ultimately developed on the site is this (House F):



Totalling 169 m2, the first floor of the house serves as an office for the architect and as an open space for the local community. The firm opens up the space to people who may want to stop in for coffee (or just hang out) and for movie nights. There's even a "plant-sharing network" on the terrace where dozens of households supposedly contribute and participate. On the second and third floor of the house are the domestic quarters. Here there are two generous bedrooms, study spaces, and multiple balconies, one of which provides access to a rooftop terrace.
It's a highly livable house, but it's also designed to meet a particular set of ambitions. I mean, look at the above coffee window. And this is one of the really cool things about domestic architecture in Japan. (If any of you are familiar with how the zoning would work for a site like this, I'd love to understand that.)
