Impressive.

Can this be used to pinpoint and identify developing ‘clusters’? A pandemic is a form of ‘natural’ disaster.

- “Given Japan's exposure to natural disasters, ranging from earthquakes to typhoons, understanding vulnerabilities is key, said Takeda.” -

Can it be used adversely, for example, showing areas where people are congregating and business are not complying with SOE’s?

- “Projection-mapping on top of the model offers a range of information -- including where businesses and populations are concentrated.’ -

The lack of green space in Tokyo is horrific.

I'm wondering if this can be used to track he Tokyo Crow population.

Do Japanese hate green space that much?

Do Japanese hate green space that much?

Truly, yes. Every year, out here in my Tokyo suburb, more and more trees are cut down, and never replaced. On our main road there is a line of tree stumps, all that remain from some lovely trees that were cut down years ago.

The little river I take my daily walk along used to have some fabulous trees; they weren't cut down entirely, but over the past decade they've been trimmed back so ruthlessly that they are now little more than sticks. Such trees look so sad and can't support nesting birds or anything like that.

Sadly, most Japanese support the removal of trees from the city because they don't like nature, they find it ugly. In our street last week there were two old people out in the morning sweeping up the fallen cherry blossom petals!

(Cherry blossoms are the only trees that don't get cut down here, and the only trees that get appreciated, but yep, all those glorious petals on the ground, the old folk here can't help but get out there and sweep them up!)

I see a lot of green in that first picture.

Very oool.

It probably already exists on different websites, but it would be good to have an online map with differently coloured overlays for the data they are using here.

Project mapping onto a 3D map is cool, but not essential to get the same message across.

Some of the butchered roadside trees are sycamores, a copy of the trees that line the Champs-Élysées and the Thames in London and easily recognizable from blotchy bark and similar leaves to the maple on the Canadian flag. Sycamores are huge spreading trees that are provide great shade on a 70m wide European street but don't work on narrow Japanese ones. They should be replaced with more upright and compact trees, such as katsura. You can see full size unpruned sycamores in Shinjuku Gyoen.

Yeah, a lot of built-up, non green, densely populated areas are coloured green in that first picture for some reason.

Tokyo the world’s ugliest city. Exactly zero city planning!

Tokyo, as you've never seen it before.

And as you'll never see it again.

Tokyo has more parks than most other big cities I’ve been to. I enjoy going to a new one every time.

This 3-D projection mapping will hopefully spread wider for all regional cities as well. Easy to comprehend zones and concentrations for any number of things.

And re greenspaces - here are a few major cities and their %s of greenspace (some accounts vary slightly)

Tokyo - 7.5%

London - 33%

Sydney - 46%

N.Y. - 27%

Singapore - 47%

Seoul - 27%

Shanghai - 16%

...how about natural forests, meadows, and such, not engineered and built by humans?

Tokyo is just a massive concrete miasma without end.

I have an allergic reaction when flying over it...

here are a few major cities and their %s of greenspace

Those numbers (source: worldcitiescultureforum) include all the governing area that a certain city border includes, e.g. HongKong includes all the New Territories and therefore reaches 40%, on the other hand if you compare Paris, which has a very tight city limit comparable to Tokyo, it's just 9%. Taipei, although surrounded by a lot of green has in its tight city limits just 3% of green space. So, those numbers cannot be compared unless you also take the city border into account. If you actually took the whole of Tokyo, which stretches west far into the mountains, the number would be totally different.

Then why do you do it?

Exactly zero city planning!

While this of course is untrue, but the mix makes this city very interesting and adventurous building wise, never gets boring when walking though the wards.

Concrete jungles where is the trees?

one of the reason I moved outside

1- no green

2- life too much expensive

3- rental and parking crazy

Humans need green, however for daily life I'm quite satisfied with lots of indoor and deck plants, the gorgeous hydrangea and other greenery on sidewalks all over Tokyo, and local parks. Building vertically and infill (using property in the city, tearing down old buildings and using the space for new ones) allows natural green spaces outside the urban growth boundary to flourish. We can easily get to wilder spaces, parks, hiking areas.
