we have both soft and hard strategies.

to treat stormwater, we have watergates, an underground reservoir, drainage system.
but it's hard to treat all stormwater by the government.
you can read the detail on this site "https://gaikaku.jp/"

therefore, every household should install a stormwater treatment facility in their house.

resilient society needs not only the construction but also the software system.
we can experiment floods on an ordinary day via an AR camera.
by experiment floods in AR, we can learn correct evacuation routes.

also in Tokyo, they constructed some landfills called Tokyo bey area.
this area is much higher than the sea level, so relatively less prone to floods or tsunami.
