A visionary mayor saved town in Japan

His tsunami wall was once considered a costly folly.

Tsunami destruction was limited to the seaward side of the enormous floodgate in Fudai, in northern Japan. The 51-foot-high structure built in the 1970s at a cost of more than $30 million in today's dollars spared the town of 3,000.

FUDAI, Japan - In the rubble of Japan's northeast coast, one small village stands as tall as ever after the tsunami. No homes were swept away. In fact, they barely got wet.

Fudai is the village that survived - thanks to a huge wall that once was deemed a mayor's expensive folly and that now has been vindicated as the community's salvation.

The 3,000 people living between mountains behind a cove owe their lives to a late leader who saw the devastation of an earlier tsunami and made it the priority of his four-decade tenure to defend his people from the next one.

His 51-foot-high floodgate, between mountainsides, took a dozen years to build and more than $30 million in today's dollars.

"It cost a lot of money. But without it, Fudai would have disappeared," said seaweed fisherman Satoshi Kaneko, 55, whose business is ruined but who is happy to have his family and home intact.

The floodgate project was criticized as wasteful in the 1970s. But the gate and an equally high seawall behind the community's adjacent fishing port protected Fudai from the waves that obliterated so many towns on March 11. Two months after the disaster, more than 25,000 Japanese are missing or dead.

"However you look at it, the effectiveness of the floodgate and seawall was truly impressive," Fudai Mayor Hiroshi Fukawatari said.

Towns to the north and south also had seawalls, breakwaters, and other protective structures. But none were as high as Fudai's.

The town of Taro believed it had the ultimate fort - a double-layered 33-foot-high seawall spanning 1.6 miles across a bay. It proved no match for the tsunami.

In Fudai, the waves rose as high as 66 feet, so some ocean water did flow over the wall, but it caused minimal damage.

The gate broke the tsunami's main thrust. And the community is lucky to have two mountainsides flanking the gate, offering a natural barrier.

The man credited with saving Fudai is the late Kotaku Wamura, a 10-term mayor whose political reign began in the ashes of World War II and ended in 1987.

Fudai, 320 miles north of Tokyo, depends on the sea. Fishermen boast of the seaweed they harvest. A pretty, white-sand beach lures tourists every summer.

But Wamura never forgot how quickly the sea could turn. Massive earthquake-triggered tsunamis flattened Japan's northeast coast in 1933 and 1896. In Fudai, the disasters destroyed hundreds of homes and killed 439 people.

"When I saw bodies being dug up from the piles of earth, I did not know what to say. I had no words," Wamura wrote of the 1933 tsunami in his book about Fudai, A 40-Year Fight Against Poverty.

He vowed it would never happen again.

In 1967, the town erected a 51-foot-high seawall to shield homes behind the fishing port. But Wamura wasn't finished. He had a bigger project in mind for the cove up the road, where most of the community was situated. That area needed a floodgate with panels that could be lifted to allow the Fudai River to empty into the cove and lowered to block tsunamis.

He insisted the structure be as tall as the seawall. The village council initially balked.

"They weren't necessarily against the idea of floodgates, just the size," said Yuzo Mifune, head of Fudai's resident services and an unofficial floodgate historian. "But Wamura somehow persuaded them that this was the only way to protect lives."

Construction began in 1972 despite concerns about its size as well as bitterness among landowners forced to sell land to the government.

Even Fukawatari, who helped oversee construction, had his doubts. "I did wonder whether we needed something this big," he said.

The concrete structure spanning 673 feet was completed in 1984. The 3.56 billion yen cost was split between the prefecture and the central government, which financed public works as part of its postwar economic strategy.

On March 11, after the 9.0 earthquake hit, workers used remote controls to shut the floodgate's four main panels. Smaller panels on the sides jammed, and a firefighter rushed down to shut them by hand.

The tsunami battered the white beach in the cove, leaving debris and fallen trees. But behind the floodgate, the village is virtually untouched.

Fudai Elementary School is just a few minutes walk inland. It looks the same as it did on March 10. A group of boys recently ran laps around a baseball field that was clear of the junk piled up in other coastal neighborhoods.

Their coach, Sachio Kamimukai, was born and raised in Fudai. He said he never thought much about the floodgate until the tsunami. "It was just always something that was there," Kamimukai, 36, said. "But I'm very thankful now."

Wamura left office three years after the floodgate was completed. He died in 1997 at age 88. Since the tsunami, residents have been visiting his grave to pay respects.

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."
