Seven years after tsunami, Japanese stay uneasily with seawalls

RIKUZENTAKATA, Japan – When a large earthquake struck in 2011, Japanese oyster fisherman Atsushi Fujita was working as typical by the ocean. Quickly after, an enormous black wave slammed into his metropolis and killed practically 2,000 individuals.

Seven years on, Fujita and hundreds like him alongside Japan’s northeast coast have rebuilt their lives alongside big sea partitions that consultants say will shield them if one other big tsunami, which some see as inevitable in a seismically lively nation like Japan, was to strike.

The 12.5-metre (41-ft) concrete wall changed a 4-metre breakwater that was swamped within the March 11, 2011 catastrophe. The earthquake and tsunami, which reached as excessive as 30 meters in some areas, killed practically 18,000 individuals throughout Japan and triggered a nuclear meltdown on the Fukushima energy plant.

“It appears like we’re in jail, though we have not carried out something dangerous,” the 52-year-old Fujita stated.

Because the catastrophe, some cities have forbidden development in flat areas nearest the coast and have relocated residents to larger land. Others, equivalent to Rikuzentakata, have raised the extent of their land by a number of meters earlier than establishing new buildings.

A standard thread, although, is the development of seawalls to exchange breakwaters that have been overwhelmed by the tsunami. Some 395 km (245 miles) of partitions have been constructed at a price of 1.35 trillion yen ($12.74 billion).

“The seawalls will halt tsunamis and forestall them from inundating the land,” stated Hiroyasu Kawai, researcher on the Port and Airport Analysis Institute in Yokosuka, close to Tokyo.

“Even when the tsunami is larger than the wall, the wall will delay flooding and assure extra time for evacuation.”


Many residents initially welcomed the concept of the partitions however have grow to be extra essential over time. Some say they weren’t consulted sufficient within the planning phases or that cash spent on the partitions has meant that different rebuilding, equivalent to housing, has fallen behind.

Others fear the partitions will injury tourism.

“About 50 years in the past, we got here up right here with the children and loved drives alongside the gorgeous ocean and bays,” stated Reiko Iijima, a vacationer from central Japan, who was consuming at an oyster restaurant throughout from the seawall.

“Now, there’s not even a hint of that.”

A part of a wall within the metropolis of Kesennuma, additional south, has home windows in it – however these, too, draw complaints.

“They are a parody,” stated Yuichiro Ito, who misplaced his dwelling and youthful brother within the tsunami. “It is simply to maintain us proud of one thing we by no means needed within the first place.”

Fisherman Fujita stated that whereas the tsunami had improved oyster farming within the space by stirring up sea flooring and eradicating collected sludge, the ocean partitions might block pure water flows from the land and impression future manufacturing.

Many municipalities stated the large partitions needed to be in place earlier than permission could possibly be granted for reconstruction elsewhere.

“I am unable to say issues like ‘the wall needs to be decrease’ or ‘we do not want it,'” stated Katsuhiro Hatakeyama, who has rebuilt his mattress and breakfast enterprise in the identical location as earlier than. “It is because of the wall that I might rebuild, and now have a job.”

However many discover the wall laborious to regulate to.

“Everybody right here has lived with the ocean, via generations,” stated Sotaro Usui, head of a tuna provide firm. “The wall retains us aside – and that is insufferable.”
