7 years after tidal wave, Japanese online uncomfortably with seawalls

RIKUZENTAKATA, Japan – When a large quake struck in 2011, Japanese oyster angler Atsushi Fujita was functioning customarily by the sea. Right after, a massive black wave knocked right into his city and also eliminated virtually 2,000 individuals.

7 years on, Fujita and also thousands like him along Japan’s northeast coastline have actually reconstructed their lives together with big sea wall surfaces that specialists claim will certainly shield them if an additional large tidal wave, which some view as inescapable in a seismically energetic country like Japan, was to strike.

The 12.5- metre (41- feet) concrete wall surface changed a 4-metre breakwater that was overloaded in the March 11, 2011 catastrophe. The quake and also tidal wave, which got to as high as 30 meters in some locations, eliminated virtually 18,000 individuals throughout Japan and also caused a nuclear crisis at the Fukushima nuclear power plant.

” It seems like we remain in prison, although we have not done anything negative,” the 52- year-old Fujita stated.

Considering that the catastrophe, some communities have actually restricted building in level locations nearest the coastline and also have actually moved locals to greater land. Others, such as Rikuzentakata, have actually elevated the degree of their land by a number of meters prior to building brand-new structures.

A typical string, however, is the building of seawalls to change breakwaters that were bewildered by the tidal wave. Some 395 kilometres (245 miles) of wall surfaces have actually been constructed at an expense of 1.35 trillion yen ($1274 billion).

” The seawalls will certainly stop tidal waves and also stop them from flooding the land,” stated Hiroyasu Kawai, scientist at the Port and also Flight Terminal Research Study Institute in Yokosuka, near Tokyo.

” Also if the tidal wave is larger compared to the wall surface, the wall surface will certainly postpone flooding and also assure even more time for discharge.”


Lots of locals originally invited the concept of the wall surfaces yet have actually ended up being much more vital gradually. Some claim they were not spoken with sufficient in the drawing board or that cash invested in the wall surfaces has actually indicated that restoring, such as real estate, has actually fallen back.

Others stress the wall surfaces will certainly harm tourist.

” Around 50 years earlier, we showed up below with the children and also appreciated drives along the stunning sea and also bays,” stated Reiko Iijima, a vacationer from main Japan, that was consuming at an oyster dining establishment throughout from the seawall.

” Currently, there’s not also a trace of that.”

Component of a wall surface in the city of Kesennuma, additional southern, has home windows in it – yet these, also, attract problems.

” They’re an apology,” stated Yuichiro Ito, that shed his residence and also more youthful bro in the tidal wave. “It’s simply to maintain us delighted with something we never ever desired to begin with.”

Angler Fujita stated that while the tidal wave had actually enhanced oyster farming in the location by stimulating sea floorings and also eliminating gathered sludge, the sea wall surfaces can obstruct all-natural water moves from the land and also effect future manufacturing.

Lots of districts stated the large wall surfaces needed to remain in location prior to authorization can be provided for restoration in other places.

” I can not claim points like ‘the wall surface need to be reduced’ or ‘we do not require it,'” stated Katsuhiro Hatakeyama, that has actually reconstructed his b and b service in the very same area as previously. “It’s many thanks to the wall surface that I can reconstruct, and also currently work.”

Yet several locate the wall surface tough to get used to.

” Everybody below has actually dealt with the sea, with generations,” stated Sotaro Usui, head of a tuna supply firm. “The wall surface maintains us apart – which’s intolerable.”
