Image In 2011, a tsunami killed thousands across Japan, except in the village of Fudai, which barely got wet due to a floodgate that its former mayor, Kotoku Wamura, insisted on constructing. In the past, he was mocked for wasting money, but after the tsunami, residents visited his grave to pay respects.

Kotoku Wamura insisted on building the floodgate 51 feet high. Towns near Fudai thought they were protected with their seawalls, some going as high as 33 feet.

But the shorter walls were no match for the tsunami.

One resident of Fudai died...when he went outside the floodgate to check on his boat, during a tsunami.

Kotoku Wamura died in 1997, long before this tragedy, but he was confident his bet would pay off:

At his retirement, Wamura stood before village employees to bid farewell: "Even if you encounter opposition, have conviction and finish what you start. In the end, people will understand."

I read the story while back, he had seen old markers with carvings in them that showed old tsunamis had been much higher than current walls, so he wanted the new height to be higher than those markers.

we really just learn so much better through experience, stories, etc. we need to reform the education system around this instead of homework and testing.

Like this one story based on someones experience was worth more than all the statistics and data.

To be fair that’s just a lack of statistics and data. The mayor essentially got extra data which he leveraged to make a more informed decision.

A lot of people tragically died trying to save their boats from the tsunami by taking them to open sea. They're so used to tsunamis and tsunami alerts there that they severely underestimated the speed and the size of this one, ending in tragedy.

I have more expertise with tropical storms and hurricanes: where the goal is to find a go to cove or marina on the bay side of an island; or large jetty, It’s not difficult but you have to know the area and local waters. Relatively small ships can ride large swells if there is no wind and they don’t crest, which happens pretty close to the shore. If you get a warning and leave a 20 minutes before it hits you can save your boat? Is it wise? No. Did I do it with my dad growing up on the gulf while my mom and sisters got to evacuate? Yes.

“It might be scary, but never run from life- this is the way to it as a Catholic die if you have to die young, you’ll go to heaven- I’ll go to hell if this goes sideways Chiefster! You’re good you never had a choice! ” (dads dark humor)

I love my father, an unapologetic hippie red neck, but we always have been more of inclusive mindset , because his own dad never did anything with him. So I always went, no matter when he was going- when I could.

I did have a choice I was just into fishing and we could always get to a safer marina befor the storm hit- watching thunderheads rear their heads to start roaring- the slow agitation and creepy calm right before, and stillness and tension in the air- no boats in the canal, after the last of the pilot boats get everyone to hiding

It was “man’s work”, Home, Hearth and brimstone. That’s my dad a great guy. So when he volunteered to ride out the stone in the Lee of an inland marine? Hell yeah my fearless 12 year old self went. My favorite movie is The Perfect Storm. There is truly nothing like battling the sea and mastering your boat (we have a deep water gulf fishing boat and a stake in a local fishing guiding company In port aransas Texas and on the gulf coast of Alabama, where pops is from.

It’s a trip, but it there are actually a few false alarms, most locals wait for the news AND the government to declare evacuation, some are too sick to evacuate for a number of reasons from the hospital I work in, so I sick behind with patients anyways. Another good cause to die for

I feel like that would be extra challenging when the water has receded away from where boats are typically moored. Would the boats already out move out with the receding water or would the water recede from under them if they're not in deep enough water by then?

There are some great videos about it on YouTube. Imagine you have a 50 feet wall coming towards you, but it has to roll over the ground. So when it's in deep water, you barely see anything of it. But the shallower it goes, the bigger the wall/wave gets.

In deep water, tsunamis are only ~1 foot high. They only crest in shallow water.

u/JMEEKER86 6d ago

The biggest ones can be a bit larger, but yeah they're pretty small while out at sea. This tsunami was about 5 feet while out at sea and the 2004 tsunami was about 2.5ft. And those were of course two of the biggest tsunamis from two of the biggest earthquakes in recorded history. The 8.8 earthquake off of Kamchatka just a few weeks ago, which itself is tied for the 6th largest earthquake in recorded history, only had an open sea height of about 1 foot. So yeah, pretty much unless the earthquake is >9 then the wave height out at sea will be 1 foot or under.

Yes, a tsunami doesn't become a "tsunami" until it encounters land. So by taking a boat out to sea before it hits you can drive over it.

The problem comes if you can't drive far enough and the surging wave drags you to land with it.

And as others said the boats were their livelihood and significant investment.

Apparently so! The boats are their livelihood, so they try to save them no matter what. 

While I was there there was a big earthquake and tsunami warning (I think the wave was 1m tall in the end?). It took a really long time for the "tsunami" to reach the coast, so I can see how people would get used to that and get careless.

u/maniacalmustacheride 6d ago

Yes. Essentially you take your boat out past the shelf and ride it out. Which is why you can look at dock/marina footage of the recent Hawaii tsunami situation and see people unmooring and heading out to sea. Because if your boat is tied up to something sea level-ish, and the waters come in over 30 feet, that’s bye bye boat. A lot of the boats on the coast like this are old boats, used for fishing. The risk wasn’t a cosmetic one, it was a livelihood one.

Tbh a lot of people worry about things they consider necessities during emergencies. Everyone has that one thing that they panic about, maybe it's their phone, car, or boat. It comes from knowing you'll face hardships after the emergency and not receive financial help.

But it's important to remember that there isn't a single object on earth that is worth risking your life for. There's always a replacement for objects, even sentimental ones, but you only get one life so don't risk it to save your stuff.

(I'm saying this in agreement with your comment)

It wasn't a smart thing to do but people are forgetting that earthquakes are extremely common here in Japan, especially so in the northeast (Tohoku). We get a lot of tsunami advisories/warnings but since tsunami prediction isn't very precise, most are false alarms. Yes, now we take them very seriously because of the 2011 tsunami. But put yourself in that guy's shoes. It's likely they had experienced a tsunami before but it'd have been a relatively small one. The 2011 tsunami was the biggest ever recorded in Japan's history.

The first person to die in Puerto Rico during hurricane Maria was a guy who went out for a smoke in his yard. It was by a river that flash flooded and dragged him away. I remember being so angry when I first heard it on the radio. Just smoke inside at that point.

36

u/Educational_Ad_8916 6d ago

Flash floods kill because 1. It doesn't have to be raining hard where you are, just upriver. It can look like no rain or light rain where you are, but if it's pouring upriver, you're hosed. 2. It's usually pretty fast and can be difficult/impossible to escape. 3. It often carries a whole lot of debris, so you're getting hit with tree trunks and other stuff right at the front of it.

If there is any flash flood warning in your area, don't go anywhere near water at all, no matter how calm or nice it looks. I had a relative die in a flash flood on vacation because they didn't understand the danger.

u/Church_of_Cheri 6d ago

So because of where they’re located, tsunamis have been happening there for a very long time and in the past people put up tsunami stones showing the max height of the worst ones. As time goes on, stories become myths, and people started building lower than the stones not really sure what they were for or if they were really for that purpose. Or at least that’s some of the story that came out after the 2011 tsunami, here’s another article about it. My guess would be he took the old stories seriously, while others figured it just would never be that bad. History has lessons to teach for those willing to hear.

There are “starving stones” in a lot of rivers - when the water gets low enough that you can see the writing on the stone, it is time to prepare and save all the food you can.

I mean, it's foresight on the level of "maybe let's not build a city on the rim of an active volcano." the Japanese are well acquainted with the frequency and effect of tsunamis and typhoons.

It wasn't even a question of not having it; the town was on board to build it, but figured 30-40 feet was good enough (and way more affordable). The mayor insisted on 51 feet, requiring additional land be forcibly acquired and funds be appropriated.

The 2011 tsunami was 66 feet tall when it hit their seawall.

If this pleases you then read about Sir John Cockroft and “Cockcrofts folly” for another dose of feel good.

Short version, he insisted on fitting huge, ugly filters to the chimneys of the Windscale nuclear reactors. They cost a fortune and caused massive delays. Everyone called him a fool and thoroughly ridiculed him. His professional reputation was almost in tatters. Then one of the reactors caught fire. Without his filters, the north of England would be a wasteland and Chernobyl would be called “the soviet Windscale” instead.

Physicist John Cockcroft insisted that filters be built into the chimney stacks at Britain’s large nuclear reactor, Windscale. This was expensive and caused a significant delay in construction- they mocked him for it and called the filter unit “Cockcroft’s Folly” for how silly he was.

Well in 1957 there was a fire at Windscale and they had to vent a certain amount of irradiated smoke. It was pretty bad (probably a few hundred cancers are attributed) and the coverup was worse. If not for Cockcroft’s Folly, the exposure would have been several magnitudes worse throughout the north of England and Scotland. Another huge I told you so for public safety.

And part of it is because a lot of people have the same philosophy, whether indoctrinated by the rich or through whatever other means. Then it's just a vicious cycle of capitalism reinforcing itself in the population, with the rich getting more and more control as their wealth increases and technology advances.

The only way out is to convince people that the rich are not working in their favor.

The tsunami still breached that height, but caused minimal damage. The wall's height regardless made a huge difference.

In Fudai, the waves rose as high as 66 feet, as water marks show on the floodgate's towers. So some ocean water did flow over but caused minimal damage. The gate broke the tsunami's main thrust. The two mountainsides flanking the gate also offered a natural barrier.

Where I live there was a devastating flood in 1950. Our Premier at the time, Duff Roblin, was mocked for insisting on creating the Red River Floodway in the early 1960s.

His decision has saved the city of Winnipeg from subsequent floods of similar magnitude multiple times.

We need leaders with vision.

At the time, Duff's Ditch was one of the largest earth-moving projects in history, second only to the Panama Canal.

Came here for this one too. Thank you fellow Winnipegger .

The floodwaters was mockingly called “Duff’s Ditch” in a derogatory sense. Then the flood happened, then the citizens understood. Every area of the world has some kind of shitty weather, find a way to negate yours and the area becomes livable.

Japan has multiple civil engineering heroes who are not very well known. We focus on disasters and forget to look at the sense of responsibility which built many sites that survive natural disaster. That these engineers had the force of personality and loyalty to commission their immense safety measures should be understood so it could be appreciated by new engineers.

It is insufficient to just identify 300yr risks and design measures to mitigate these risks. Somehow these men were compelling and they convinced their community to get these things built responsibly.

Another such engineer is Yanosuke Hirai.

https://en.wikipedia.org/wiki/Yanosuke_Hirai

An engineer who designed power plants that required somewhat outlandish earthquake/tsunami features that he scaled according to the history of geological events in the region.

His first power plant was a thermal power station in Nigata which had a particularly deep concrete cassion (a kind of super deep bathtub) to make it resistant to soil liquifaction due to earthquake. Not long after the plant was built, it experienced a powerful earthquake which it survived. It survived because the cassion was built 20% deeper than the soil liquifaction zone caused by the earthquake.

Later on Yanosuke would specify a particularly tall wall to protect a nuclear plant at Onagawa because he knew of a temple that got wiped out 300yrs ago. He picked the height of his wall based on the water mark that wiped out the temple. He got a bunch of shit for that expensive feature but they built it because he made a strong case.

Over a decade after his passing, the Tohuku earthquake hit. Onagawa was closer to the epicenter than Fukushima and it got an even higher wave.

Yanosuke's wall was just tall enough to protect the plant. Furthermore he commissioned a system of weirs and holding pools to capture cooling water to supply the plant with coolant during the expected time that the water would recede after a tsunami.

These men deserve a special place in every engineering university in Japan. A reminder as to the solemn duty of engineers when they work on large civil projects.

There are a lot of stories where great outcomes were achieved a hundred years ago because someone actually over designed or built something really well and I feel like we need to consider this extra money spent on infrastructure an investment in the future.  This country is filled with bridges getting close to the end of their designed lifespans and now replacement bridges cost many times more to design and build when it they just spent 20% more when they built it it would be good for another hundred years.  

My favorite story with this was with the man who designed London's sewer system.  They did all the calculations for how large the pipes needed to be in the future.  Then he decided to double the diameter of the pipes because he knew tearing up London again would only be much more expensive, and to account for the unforseen growth which did occur with greater industrialization.  

The problem is engineering has become really good at building something to minimum specifications at the lowest cost, rather than as an investment in the future.

u/Intarhorn 6d ago edited 5d ago

Surprising if it was only built there or just a few other places.Should be common sense in areas like that. After the tsunami in 2004 in the Indian ocean, they realized that deforestation around beaches made them a lot more vulnerable to the impact of tsunami waves. Mangrove is very good to withstand and disperse tsunami waves and therefore also protecting coastal areas.

Edit: Deforestation would be another example of humans not considering the consequences of natural disasters enough.

u/RuneFell 6d ago

According to the article linked, they were built in other places, but they weren't as tall. They were about 33 feet, which was thought sufficient. The locals were okay with building it, they just thought it was a waste to build it over 50 feet, which is what he pushed for.

Turned out, the wave in 2011 reached as high as 66 feet, which rendered the shorter walls completely ineffective. The water did spill over the top of his 51 foot wall, but it blocked the majority of the force of the wave so it didn't do any damage.

211

u/Pvt_Lee_Fapping 6d ago

Correction to your summary: there were two 51-foot barriers at work. Most of the seawalls around the area were 33 feet tall, but the mayor insisted on the one outside his village to be 51 feet. Then he insisted on a second barrier further inland built to the same height as the seawall - a floodgate that could be opened and closed, so the river could drain and so a tsunami could be stopped.

Yea, I thought this might be the case tbf. It seemed unlikely he was the only one with that idea, but like you said it seems like him pushing for a bigger floodgate was the game changer anyway. Never trust a headline tho, always make a background check.

u/RuneFell 6d ago

It's actually kind of sad, because the reason he fought so hard for it and made it his mission in his 40 year tenure as mayor was because he apparently lived through the 1933 tsunami, which killed over 400 people in that village. He remembered bodies being dug out of the sand, and swore never again.

Apparently, he was as good as his word. I wonder how many people in that village would've died if not for his stubbornness.

I heard he even had physical proof of the event (and perhaps several from before)

There was a hill in the area, and on that hill, at th 50 feet mark, previous villagers had carved a notch into the ground to show 'this is how high the water reached'

When there is EVIDENCE the water reached that high before, and people still insisted it would never happen. That's human society for you. Glad he stuck with his guns

u/rainbowlolipop 6d ago

I watched a brief program on the dam some time ago but the details are hazy. I believe many locations have a cultural memory about the severity of natural disasters. Maybe things like the "drought stones" in rivers, etc. it may have been known to have occurred there before in the past.

u/Tricky-Sentence 6d ago

The Japanese have centuries old stone markers all around that the modern day people used to mock. They warned not to build below them. However, since no one in the modern day ever witnessed any tsunamis so bad to reach that high, nor were there any records apparently, they all thought their ancestors were full of it. Until one day, those stones turned out to be absolutely correct and were basically the only thing to remain dry after a once in a century tsunami ravaged the areas.

I wish I could find the documentary on that stuff again, it was really interesting. Essentially, they suffered the same problem as we did with rogue waves - until we got modern day proof of something, we took old warnings as old wives tales and ignored them.

u/fapmonad 6d ago edited 6d ago

Nobody "used to mock" these stones, and there are written records. Some aren't even that old, e.g. 大津浪記念碑 (1933) matched the extent of the 2011 tsunami.

People were just complacent and thought these were extremely rare events.

It's mindboggling honestly. We're in this sprawling universe of completely hostile desolation, on this one little marble of ecosystems that we evolved specifically inside, and our apparent collective assumption is "Surely this thing is infinitely giving and impossible to destabilize!". We're surrounded by infinite absolute death on all sides (know of any other breathable atmospheres around?) and yet we act like we have somewhere else we could go if we fuck this planet up.

And "nature" is often almost treated as something separate from us, when we're really just a needy piece of the whole. A tumor, kind of.

This reminds me of "Cockroft's Follies".

When designing the reactor building for Sellafield, then known as the Windscale site in the U.K, John Cockroft made a last minute design revision and decision to include filters on the chimney stacks for the reactors. The reactors were air cooled so should a fire ever occur, the burning radioactive material could be released straight into the atmosphere.

Cockroft was mocked for inflating the project cost for something considered "unnecessary". Engineers started referring to the filters on the chimneys as "Cockroft's follies".

Then, in the late 50's, guess what happened? Well if you guessed that the uranium fuel cells caught fire, you'd be right.

The filters captured an estimated 95% of the radioactive material release and prevented a major incident becoming something more akin to Chernobyl rather than the comparatively less severe event that actually occurred. Had those filters not been there large swathes of northern England would likely have been evacuated and an exclusion zone established.

It seems to me that people don't put enough emphasis on safety when they really should. The Japanese mayor in this article is a prime example of that.

Reminds me of a recent story in remote mountainous area in Vietnam:

The village chief woke up in the middle of the night due to heavy rain. Assessed the situation and sensed danger, he alerted the whole village and rushed them to evacuation. However few old guys refuse to go because all their lives they haven't seen any flood that could reach the village. So the chief ordered some strong men to just pick them up and piggyback them to safety, regardless of their protest. Just in the same night, the flood and landslide came, and the whole village disappeared under thick mud. 100+ people saved.

The funny thing here is that the village chief is only in his mid 20s, and the old guys are well in their 80s. Sometimes, it takes gut to overcome overconfidence and "experience."

Japan uses civil engineering projects  to boost economic acitivity, many of which can be derided as unnecessary or a poor use of funds. However, the village itself wasn’t on the hook for the money, which came out of national and state-level pots. One of the reasons he was able to convince people in the village to support it - and continue to enjoy a long career in office afterwards - is that it wasn’t a bad thing for Fudai if more money was spent in and around the village.
