One of the truly remarkable things about Tokyo is that it manages to be both the largest metropolitan area in the world and one of the most livable cities in the world. That's quite an accomplishment. And one of the key ingredients has to be its heavy reliance on rail for mobility. Look at any list of the busiest train stations in the world and you'll find that the majority of them are in Japan.

But what does this mean for the average person living in a city like Tokyo? Well, every 10 years Tokyo does a "person trip survey" that looks at how people get around. And if you look at the last set of results from 2018, you'll find the following modal splits:

• 33% railway

• 27% private car

• 23% walking

• 13% bicycle

• 4% other (bus and motorcycle)

This is a big deal. Supposedly this is the highest railway split in the world. But the numbers may be even better than this. According to a recent book by Daniel Knowles, who is a correspondent for The Economist, only about 12% of trips in Tokyo are done with a car, giving the city one of the lowest driving rates in the world. Bike usage is also higher than the above at 17%.

Whatever the exact numbers are, it is clear that there's a heavy bias toward rail and other forms of non-car mobility. And you feel that in the city. You feel it in the lack of traffic congestion (which incidentally makes the city feel generally quieter and calmer) and you feel it in the way that density and pedestrian traffic is obviously concentrated around stations.

In the span of a 10 minute walk, you can go from feeling like you are, in fact, in a giant megacity, to feeling like you're in a tranquil community where grade-separated sidewalks aren't even needed because the cars, if any, all drive so slowly. It's an interesting dichotomy that is the result of true transit-oriented development.

On-street parking is also virtually non-existent. According to Knowles, 95% of streets in Japan do not allow it, either day or night.

At the same time, this approach makes it easier to get around by car. We have taken a handful of Ubers on this trip, and they always arrived in a few minutes, and we have yet to be stuck in soul-crushing traffic. It's perhaps ironic that in a city many multiples larger than Toronto, it feels easier to move around. Or maybe it just goes to show you that it's not about how much urban space you have, it's about how efficiently you use it.
