00:00On March 11, 2011 at 2.46 in the afternoon in Japan, a magnitude 9.1 earthquake suddenly split
00:07the floor of the Pacific Ocean. The crack along the coast of Japan reached almost 400 kilometers
00:13in length. No broadcast tonight, the big one hits Japan, a massive history-making earthquake.
00:30One of the largest ever measured. And it triggers a massive tsunami all the way to the U.S.
00:35A 40.5-meter wave, six minutes. Almost 18,000 people lost their lives by nightfall. No less
00:43than 1,000 people were reported dead or missing in the first hours after the disaster. And the
00:49number of victims continued to rise as time passed. Japan's warning system had never experienced such
00:55a massive wave before. The Pacific Ocean had never pushed this much water in a single wave,
01:01and not a single nuclear power plant in the world was designed to withstand the disaster
01:07that was coming. This is the story of the giant wave that almost wiped out all of Japan.
01:14But before we begin, if you're new to our channel, make sure to subscribe so you'll
01:19always be updated with videos like this. On the shores facing the Pacific Ocean, in small villages
01:27rarely visited by tourists, there are ancient stone markers carved into the cliffs. Some of these are
01:34over 600 years old. They all bear the same message. Do not build houses below this area. Japan has lived
01:43with earthquakes in the same way other countries live with rain. This is because the country is
01:48located at the intersection of four tectonic plates. That's why it's one of the most active places in
01:54the world when it comes to earthquakes. The earliest written record about a tsunami on the coast of Tohoku
01:59dates back to the year 869. For more than a thousand years, Japan has been preparing for this very day.
02:07By 2011, Japan also had the most advanced earthquake warning system in the world.
02:12The sensors placed under the sea send real-time data to central monitoring stations.
02:18The sirens reach almost every town in the bay. Within just a few seconds,
02:24millions of people received tsunami warnings on their cell phones. The seawalls along most of the
02:29coastline were built to withstand waves up to six meters high. Even the nuclear power plants were
02:35designed for the most extreme disasters engineers could imagine. But the worst-case scenario they expected
02:41was wrong. According to the hazard maps used by towns like Okawa, north of Sendai, the tsunami was not
02:48expected to reach more than a few hundred meters inland. The seawall at the Fukushima Daiichi nuclear
02:54power plant was built to block waves that were only about six meters high. However, the highest tsunami
03:00recorded up to that point in that part of the coast, the Sanriku tsunami in 1896 reached 38.2 meters.
03:08In 2011, the height of the wave that hit Miyako reached 40.5 meters. The warnings were already there.
03:16And they had been there for a long time. By 2.46 in the afternoon, the ocean floor suddenly split
03:23open.
03:23In Tokyo, which is more than 300 kilometers away from the center of the earthquake, buildings swayed for a
03:30full six minutes. The tall buildings in the Shinjuku district bent and swayed like trees being battered
03:37by a powerful storm. But in Sendai, which is closer to the epicenter, the ground didn't just shake.
03:44It seemed to suddenly ripple and slip away from under people's feet. People on the streets could barely
03:50stand. Tables, cabinets, and other furniture slid across the floor on their own. Items came crashing down
03:58from the shelves. After just three minutes, the Japan Meteorological Agency issued the highest tsunami
04:04warning. Sirens blared all along the Tohoku coastline. In the coastal towns, loudspeakers
04:10repeatedly announced a very important order, immediately move to higher ground. However,
04:17at that moment, many people were still preoccupied with the earthquake itself. Some were still taking
04:23shelter under their desks. Others hurried outside their homes to make sure their loved ones were safe.
04:31In Japan, tsunami warnings are coming. Usually, no big waves follow. But this time was different. While
04:39the ground was still shaking, the ocean floor along a 400-kilometer fault line suddenly rose by up to 10
04:46meters. Because of this, billions of tons of water were pushed upward and had nowhere else to go but to
04:54spread rapidly in all directions. In the middle of the Pacific Ocean, the tsunami moved at a speed of
05:00about 700 kilometers per hour, almost as fast as a jet airliner. From the surface of the sea,
05:06it was almost unnoticeable. It just looked like a long and gentle wave. But as it approached the shallow
05:13part of the shore, the massive volume of water began to compress and rise. A wave that was only
05:19about a meter high in the middle of the ocean became a gigantic wall of water, with a height of
05:2510,
05:2520, up to 30 meters when it reached the shore. 20 minutes after the earthquake, the first waves hit
05:31the northern coast of Tohoku. In Sendai, the interval before the tsunami arrived was even shorter.
05:38For people living on the coast, there is a definite sequence of signs. First,
05:44the sea suddenly recedes. Hundreds of meters of beach suddenly appear. The boats docked at the port
05:50were left on dry sand. The older fishermen immediately recognized this. This was the
05:55warning their ancestors had taught them. The sea breathes in before it breathes out. After this,
06:01a strange sound came. A deep rumble that seemed like an approaching train. But as each second passed,
06:07it grew louder. It came closer. Until it became even more terrifying than any train you could ever
06:14hear. Eventually, many survivors described it the same way. It was like their whole life was slowly
06:20falling apart. And then, a dark line appeared on the distant horizon. As it got closer, it no longer
06:26looked like a line. It had become a massive wall of water. In Miyako, the wave reached a height of
06:3240 meters.
06:33In Kamaishi, footage from a helicopter showed how the tsunami swept over the massive sea wall.
06:39It was as if it was made of paper. The vehicles on the coastal road were first pushed sideways.
06:45Then, they were lifted by the rushing water. Before being completely swept away.
07:00In Kisanuma, almost the entire commercial fishing fleet of the city was lifted out of the harbor.
07:07Swept inland and dropped between houses, a ship, the Asia Symphony, was found stranded on a residential
07:13street the next day. More than three blocks away from the sea. Meanwhile, in Otsuchi, the raging flood
07:20completely engulfed the municipal building. This caused the officials on the upper floors to become
07:25trapped as the water continued to rise. At that very moment, all of this was happening along more than
07:31500 kilometers of coastline, while the sun was still shining brightly. The Sendai Plain is one of the
07:37widest and flattest coastal plains in Tohoku. There are kilometers of rice fields between the sea and the
07:44foothills of the mountains. There was no natural barrier to stop the rushing waves. When the tsunami
07:50came, it surged straight into Sendai Airport from the seaside. Within just 60 minutes after the earthquake,
07:56the entire first floor of the main terminal was submerged in more than three meters of dark water.
08:01The vehicles parked in the long-term parking area were swept away and crashed into the steel fences.
08:08Approximately 1,300 people, including passengers, airport employees, and residents who evacuated from
08:15the nearby community, climbed to the roof and the upper floors of the building. From there, they could
08:21do nothing but watch as the massive waves slowly engulfed the runways. Some of them still had working
08:28cell phones. They started recording videos. Those clips taken from the airport roof were eventually
08:34seen by the whole world. You can see the dark, raging water carrying cars, trees, wreckage from
08:42houses, and oil from storage tanks that were torn open by the tsunami. In some places, even the water
08:48was on fire. Right in front of the camera, entire communities slowly disappeared. The tsunami reached
08:55almost 10 kilometers inland from the coast of Sendai. In some areas, it even reached up to 15 kilometers.
09:03The rice fields turned into vast lakes. Cemeteries were dug up and destroyed. The wooden houses were
09:09uprooted from their foundations and shattered into pieces within just a few minutes. By the end of the
09:15day, more than 122,000 buildings had been completely destroyed. Almost a million others suffered varying
09:22degrees of damage. But the part that left the deepest impression on the world happened several
09:27hundred kilometers further south. At the Fukushima Daiichi nuclear power station, six nuclear reactors
09:34stood on a low cliff facing the Pacific Ocean. The seawall protecting it was 5.7 meters high.
09:41Exactly 3.27 in the afternoon, or 41 minutes after the earthquake, the first wave of the tsunami hit the
09:49seawall and most of the water was blocked. But by 3.35 in the afternoon, the second wave arrived.
09:56This wave was approximately 15 meters high. It easily passed over the seawall as if there was no
10:03barrier at all. It immediately flooded the lower floors of the reactor buildings and submerged the
10:08emergency diesel generators that powered the plant's cooling pumps. Within just one minute,
10:14the three reactors, which were still operating at that time, completely lost backup power. Although their
10:20normal operations had already stopped, the reactors continued to generate intense heat. But since the
10:26cooling system was no longer working, nothing was stopping the rapid rise in temperature. Underneath
10:33three sturdy buildings made of reinforced concrete, the three nuclear cores began to melt. This was the first
10:40tsunami in history that caused a massive nuclear disaster. While all of this was happening, thousands
10:46of ordinary people were forced to make almost impossible decisions. In the city of Ishinomaki,
10:52a man named Hideaki Akaewa was at work when the earthquake struck. His town was one of the hardest hit
10:59by the tsunami. He immediately went home, but when he arrived, he found their community submerged in more
11:05than three meters of cold, dark water. His wife of 20 years, Hiromi Akaewa, was believed to still be
11:12inside their flooded house. He could no longer wait for the rescuers, because at that moment there was
11:20no rescue team capable of helping right away. They were all busy rescuing thousands of other disaster
11:26victims. He borrowed a wetsuit from a friend. He put it on, carefully waded into the cold water,
11:32and started a swim. He swam for more than 200 meters, surrounded by drifting debris, logs, shattered
11:39glass, wrecked vehicles, pieces of houses, and other things he tried hard not to look at. Finally,
11:47he reached their own house. Only the second floor was sticking out above the water. His wife, Hyoko,
11:54was there. He was able to save her successfully, but his mission did not end there. The next day,
12:00he went back into the raging flood to look for his mother, but he could not find her. For four
12:07days, he kept coming back, searching among the destroyed houses and dangerous waters. On March 15,
12:13on the fifth day of searching, he found his mother on the second floor of another house that was
12:19submerged in the flood. She was alone, terrified but still alive. Once again, he was able to save her,
12:27and instead of stopping, he spent the following week diving into other flooded houses all over
12:33Ishinomaki to search for the missing loved ones of other families. But just a few kilometers from
12:40there, things did not end so well. At Okawa Elementary School, teachers and students gathered
12:46in the schoolyard after the earthquake stopped, exactly as stated in their disaster response plan.
12:52Some parents arrived one by one to pick up their children, but the teachers advised them to stay
12:58at the school for now. According to the official hazard map released by the prefecture in 2004,
13:04Okawa was supposedly safe from tsunamis. In the memories of the residents, a tsunami had never reached
13:10that area. 40 minutes passed. As time went by, the Japan Meteorological Agency raised the warning on the
13:17radio. The expected wave height rose from 6 meters to 10 meters. But the teachers still couldn't agree
13:24on what the right thing to do was. The situation got even worse because the school's disaster manual
13:30didn't specify where the nearest high ground for evacuation was. In the end, they decided to follow
13:37a road beside the river leading to an area about 6 to 7 meters high, but it was already too
13:43late.
13:4551 minutes after the earthquake, the massive tsunami reached the school. Most of the people who took
13:51that route did not survive. After a few years, a court in Japan decided that the school was negligent
13:58in their evacuation. The authorities were ordered to pay damages to the families of those who perished.
14:04To this day in Japan, the name Okawa remains a symbol of one of the biggest mistakes on March 11,
14:102013. Not because the tsunami was stronger there than in other places, but because the people in
14:17charge had enough time to make the right decision, yet they failed to do so. Meanwhile, inside the
14:23Fukushima Daiichi nuclear power plant, as the nuclear reactors were slowly melting down, 50 workers refused
14:30to evacuate. Eventually, they would be known as the Fukushima 50. Most of them were veteran operators and
14:37engineers, led by the plant manager Masao. For many hours, they worked in almost complete darkness,
14:44breathing air filled with radiation, and with almost none of the instruments working. They laid out
14:50hoses from the fire trucks to pump seawater into the reactors and reduce the intense heat.
14:56They also set up temporary power lines that they plugged in amidst the rubble. They hoped to restore the
15:02power supply to the plant. For several days, their families had no news about whether they were safe
15:08or still alive. When news spread that more volunteers were needed, around 250 retired Japanese engineers,
15:16most of them over 60 years old, willingly volunteered to take on the most dangerous tasks.
15:24Their explanation was simple, but very painful. Cancer caused by radiation usually appears after
15:31many decades. We don't have that many decades left to lose. The Japanese government accepted their offer.
15:39By the morning of March 12, the true extent of the damage was gradually revealed. Entire towns along the
15:46500-kilometer coastline seemed to have completely disappeared, not just damaged, but almost erased
15:52from the map. The former communities had become vast piles of broken logs, destroyed vehicles, scattered
15:59concrete, and the bodies of victims. Before the week ended, the three reactors at the Fukushima Daiichi
16:06nuclear power plant experienced partial or complete nuclear meltdowns. There were also powerful hydrogen
16:13explosions that blew off the roofs of two of the reactor buildings. Due to the danger of radiation,
16:19the government established a three-kilometer evacuation zone around the plant. Approximately
16:25150,000 residents were forced to evacuate. Most of them left without knowing when they would be able to
16:32return. And for many, they were never able to return to their homes. The number of casualties continued
16:39to rise as the days went by. Many of the victims were buried under thick rubble or swept away by
16:44the
16:44raging sea, making them difficult to find. By 2026, the official number was 15,901 confirmed dead,
16:53while 2,519 people remain missing and are presumed dead. In total, more than 18,000 people fell victim to
17:03one of the biggest tragedies in Japan's history. The direct economic damage is estimated to have
17:09reached 210 billion dollars. Up to now, it is still considered the most expensive natural disaster in
17:16recorded human history. By June 2012, nearly 347,000 people were still living in evacuation centers and
17:25temporary shelters. Many towns were later relocated away from the coast and built on higher ground to be
17:31safer from future tsunamis. Meanwhile, the former seaside communities were turned into memorial parks,
17:39wide open fields and new seawalls in remembrance of the victims of the tragedy. Japan rose again,
17:45as it always does in the face of every challenge. They built new seawalls, and some of these have
17:50reached heights of 12 to 15 meters. They also created new evacuation routes that lead to higher ground than
17:56before. And along the coastline, they once again placed stone markers as warnings for future
18:01generations. But the most important change cannot be seen in the seawalls or on the maps. For more
18:07than a century, the design of almost every seawall in Japan was based on a single belief, that the
18:13largest tsunami that happened in the past would also be the largest tsunami that could happen in the
18:18future. But after March 11, 2011, that belief was completely shattered. Currently, every city along the
18:25coast of Japan, as well as many countries around the Pacific Rim, are now preparing for a tsunami that
18:32could be even bigger than any previously recorded. The records from 869-1611, 1896, and 1933 remain an
18:42important part of their history. But now, alongside these, there is a date that will never be forgotten.
18:49March 11, 2011. The day when a massive wall of water, even higher than a 12-story building,
18:56surged in from the sea, it continued to advance more than 10 kilometers inland. It claimed more than
19:0218,000 lives caused the meltdown of three nuclear reactors, and nearly brought the entire country of
19:08Japan to its knees. Before we end, let us remember that every number mentioned in this documentary
19:15is not just a statistic. Each one had their own name, their own family, and their own dreams that
19:21suddenly disappeared in just a matter of minutes. The tragedy on March 11, 2011, serves as a reminder
19:28to the whole world that no matter how advanced technology becomes, there are still forces of
19:34nature that humans cannot control. But it also showed the resilience, courage, and unity of
19:39people who were willing to risk their own lives to save others. If you enjoyed this documentary and
