I hope everyone can stay safe and/or recover quickly. This type of weather will continue for the foreseeable future, so preparation will be key in the future.

Let's not forget storm surges also. Many sea-walls don't look high enough for something like this month's Florence and Mangkhut storms.

Isn't there any way we can control weather, I mean, weaken the forces of storms with a help of nuclear power?

Everyone complains about the weather-but nobody ever DOES anything about it!!

The major rivers in Tokyo all have a history of flooding. See Japanese wiki about the Tonegawa etc. They have huge dykes, called "super teibo" in Japanese built or being built along them. In the government plans, its something crazy like a 200-year project.

I only heard about it recently, but there are also areas of Tokyo that have sunk due to overexploitation of ground water. Some are now several meters lower.

Anyway, it would be wise to know about the area you live in and know what measures you should do when the danger level increases.

Most storms that hit Japan spawn over the sea near the Philippines - hot sea area. My idea is as soon as a new typhoon is found, we fly there and cool down the water temperature to neutralize them.

Tokyo has a very sophisticated flood control system due to the fact much of the city is essentially built on a river delta. Much of Tokyo used to frequently flood during heavy rainstorms until those flood control measures were built. Now, similar flood control systems will be needed for Nagoya and Osaka.

Amazing were Japan puts its priorities, here you have and island were natural disasters are a common occurrence and seems to be increasing year by year, yet the governments aging politicians concentrate on getting changes to the constitution and supporting an unpopular whaling agenda. This lack of support for spending on badly needed infrastructures or care for its people is not limited to Japan. Politicians rhetoric worldwide when seeking election, suddenly changes when they get elected into the big boys club.

part of an underground water discharge tunnel which was constructed to protect Tokyo and its suburb areas against floodwaters and overflow of the city's major waterways and rivers during heavy rain and typhoon seasons, at the facility in Kasukabe

been there. Its really nice. I recommend it as a day trip.

Think carefully where you live in japan

Isn't there any way we can control weather,

Geoengineering has long been looked at to do just that. https://en.wikipedia.org/wiki/Climate_engineering

However, who knows what the risks might be.

We could also reduce our current levels of polluting and come up with economic alternatives to what we're doing now. But that has the potential to change economic power structures, so the global ruling class will do all they can to stop that. After all, they're leading the climate change deniers.

The article mentions flood risk maps available on line, but doesn't provide links. Here is one link (in Japanese): http://www.gsi.go.jp/kanto/kanto41001.html

Maybe Abe can take a few minutes from his busy schedule pushing for record budgets to isolate other nations and build missile defenses, and maybe focus on far more real threats like those mentioned here. Nah.

A hundred years from now it's all gonna be under water anyway, along with most of the coastal cities throughout the world. We reached peak indifference a couple decades ago.

This is the governments portal site for hazard maps on which you can select the desired prefecture/city etc:

You can also find them on the homepages of each local government. My prefecture also has a site that has links to the maps which are available for every single city, town and village in the prefecture.

Or you can google ハザードマップ or 防災マップ plus the name of the desired locality.

I have the PDF for my local hazard map downloaded to my iPhone and keep the paper version that was distributed to all households at home.

There is lot of money being and to be made in the "Solve the global warming" business.

I really hope they have more than one inflatable boat for that part of town! Keep safe everybody! Thoughts for Melbourne Australia.

You can visit the facility in the main picture for a very modest fee, and learn a lot about flooding prevention around Tokyo. I've visited it, it looks like a humongous cathedral, but it's very disconcenting, as this hall it has almost no echo, unlike normal churches. You'll need to reserve the tour in advance. Really recommended, if you want to feel dwarfed by the proportions. Don't go during the rainy season (obviously)...
