The huge sea wall and floodgates took 12 years to build and had been widely regarded as a £20million folly. But today one former Japanese mayor is being hailed as a saviour after the grandiose construction allowed his small town escaped the devastation wrought by the March 11 tsunami.In the rubble of Japan's northeast coast, Fudai stands as tall as ever after. No homes were swept away. In fact, they barely got wet.The 3,000 residents owe their lives to the late Kotaku Wamura, who lived through an earlier tsunami and made it a priority of his four-decade tenure as mayor to defend his people from the next one.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 other towns.Since the tsunami, residents have been visiting his grave to pay respects.'It cost a lot of money. But without it, Fudai would have disappeared,' said seaweed fisherman Satoshi Kaneko, 55, whose business has been ruined but who is happy to have his family and home intact.Two months after the disaster, more than 25,000 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 braced against tsunamis with concrete seawalls, breakwaters and other protective structures. But none were as tall as Fudai's.The town of Taro believed it had the ultimate fort - a double-layered 33-foot-tall (10-meter-tall) seawall spanning 1.6 miles (2.5 kilometers) across a bay. It proved no match for the tsunami two months ago.In Fudai, the waves rose as high as 66 feet (20 meters), as water marks show on the floodgate's towers. So some ocean water did flow over 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.Fudai, about 320 miles (510 kilometers) north of Tokyo, depends on the sea. Fishermen boast of the seaweed they harvest. A pretty, white-sand beach lures tourists every summer.But 10-term mayor 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 two 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 (15.5-meter) 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 located.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 lingering concerns about its size as well as bitterness among landowners forced to sell land to the government.Even current Mayor Fukawatari, who helped oversee construction, had his doubts.'I did wonder whether we needed something this big,' he said in an interview at his office.The concrete structure spanning 673 feet (205 meters) was completed in 1984. The total bill of 3.56 billion yen was split between the prefecture and central government, which financed public works as part of its postwar economic strategy.On March 11, after the 9.0 earthquake hit, workers remotely closed the floodgate's four main panels. Smaller panels on the sides jammed, and a firefighter had to rush 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 sits no more than 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,' said Kamimukai, 36. 'But I'm very thankful now.'The floodgate works for Fudai's layout, in a narrow valley, but it wouldn't necessarily be the solution for other places, Fukawatari said.Fudai's biggest casualty was its port, where the tsunami destroyed boats, equipment and warehouses. The village estimates losses of 3.8 billion yen ($47 million) to its fisheries industry. One resident remains missing. He made the unlucky decision to check on his boat after the earthquake.Wamura, who died in 1997 at age 88, left office three years after the floodgate was completed.At his retirement, Wamura stood before village employees to bid farewell:
