Nankai Trough quake damage projected at ¥1,466 tril over 20-plus years

 ¥1,466 tril over 20-plus years

Just add that to another Japanese debt from existing debt that Japan already had.

This also has huge potential for a market crash/currency crisis. We've seen how people reacted to an increase in the rice price. Imagine how they will react if the price of other food, energy, fuel Japan relies on all instantly goes up due to the yen crashing 30% or more.

Since this is civil engineering folk, they are likely focusing on infrastructure. Civil engineers do not build houses, and words like "housing" are absent from the story. This suggests that the numbers do not include loss of housing.

This would be a good time to formulate a plan for establishing alternative government sites in the event of such a disaster. The stoppage of Japan's financial services due to the destruction of Tokyo would have dire consequences for the world.

Sounds like a LOT of $dough but in reality, impossible to calculate the true 'cost'. Thankfully, Japan's at best only 3% of global GDP this year and will be FAR smaller in the next 30 years, given aging and depopulation

"The latest estimate by the Japan Society of Civil Engineers is based on an analysis of a megaquake and subsequent tsunami along the Nankai Trough, which stretches southwest from the Pacific coast of central Japan. The figure represents a 4 percent increase from its 2018 estimate of 1,410 trillion yen."

Too much talk devoid of substance. It's best to be prepared whether the damages will be 100¥ or 1,410 trillion¥. But bearing in mind there is no known measure of lost "life/lives" value it becomes all harder to come up with proper projection or estimations. the least we can do is to keep on coming up with better natural disasters resistance infrastructures.

As a survivor of a 7.6 Earthquake whose home is located only 19 kilometres from that Earthquake's epicentre and still recovering from the Noto Peninsula Earthquake. Since we had so many aftershocks, it's been a hobby to study Earthquake activity all over Japan. If you have never been through a major earthquake near the epicentre, there is no way to understand what the experience is; the only way to describe it is the word incomprehensible 

 Even before the January 1st, 2024, Earthquake, all you heard was the Future Earthquake of the Nanki Trough, it's going to happen over the next 20 to 30 years. Ignoring the fact that Noto Peninsula and the people who experienced the Earthquake swarm since December 2020. I have been living in Noto since 2016 and I experienced the whole Earthquake swarm, the several strong Earthquakes it produced since 2020 including the May 5th 2023 Earthquakes, the January 1st 2024 Earthquake which I was in my home at the time of the Earthquake, its aftershocks, and the Earthquakes aftermath and recovery.

 How many other parts of Japan will be affected before the Naiki Earthquake that this government will ignore? Kumamoto, Noto, where else before the Nanaki Trough?

 Last year, an Earthquake Occurred at the very edge of the Nanki Trough, which had been extending to off the coast of Miyazaki in recent years. At the time the government declared an emergency because a major earthquake was expected over the next few weeks. This government could not even predict the Noto Earthquake which had an active Earthquake swarm. The only thing that came out of the Last August Earthquake emergency alert was probably an excuse to buy up the rice and create a higher-priced market, taking advantage of people's fears and creating a supply problem. That’s all that amounted to, taking advantage of a situation the LDP LED JAPANESE GOVERNMENT CREATED, which is a true insult to the people of Miyzaki and Noto who recently have suffered major Earthquakes.

 As for future earthquakes

Judging by the amount of Earthquakes that have been occurring in the Sanriku Oki go area, The area in the Pacific ocean extending off the coast of Etrofu Island, through Hokkaido, and stretching to Iwate prefecture has been very active this year. Not only this area but areas of the Sagami trough has been more active than normal which is between Izu Peninsula and Chiba Prefecture has also recently been active. On top of that a New Earthquake swarm is not affecting an area just off the coast of Yamaguchi Prefecture.

Yes, The Nanaki trough can become active at any time however how many more areas will be effected by major Earthquakes first, that you will ignore before the Nanki? If one of these major Earthquakes do affect an area with mass tourism do you have a plan for dealing with this in a major disaster area?

Realistically, it's almost impossible to predict the next great earthquake with presicion. Having said that, I also know most of us treats our planet as an object, but it's not an object but the planet is alive. And some(one/thing) a live before any ailments, first there are symptoms as indication of what going on in the body. And as an experienced survivor of 7.6 Earthquake in Noto you are in a better position to notice the symptoms better than someone with only predicative models.

Time to build more mobile hospitals, food storage depots and large evacuation helicopters ( like the Mi-26). All deep in the mountains or areas that are least likely to be affected.

This is not true - it is possible to accurately predict the location and time of earthquakes. Another issue is that seismologists do not need this, since they do not want to lose their jobs and preferences. I know this, since I have been trying to implement my technology for accurately predicting earthquakes for 14 years.
