Fudai ( Japanese 普 代 村 , - mura ) is a village community in Shimohei County in northeastern Iwate Prefecture in Japan .

geography

Fudai is located on the Pacific Ocean on the northern Sanriku coast, which is characterized by steep cliffs . The more than 100 m high Kurozaki ( 黒 崎 , dt. "Black cliffs") in the southeast are part of the Sanriku-Fukkō National Park . There are only a few sandy beaches and the settlement is concentrated on various hamlets in the few small plateaus or mountain and river valleys.

The center of the village is in the wide valley of the Fudai-gawa ( 普 代 川 ), where the 茂 市 川 flows into it. This in turn is not located directly at the mouth, but behind a flood weir, which is located about 300 m from the mouth and, like the neighboring district behind the harbor, is protected by a dike. The other districts are on an elevated area. With around 3,000 inhabitants, it is the smallest municipality in the prefecture.

The municipality borders Noda in the north , Iwaizumi in the west and Tanohata in the south .

history

Today's Fudai parish was created when the parish was reorganized on April 1, 1889 as part of the Kitahei district . This was merged on March 29, 1896 with Nakahei and Higashihei to form Shimohei County.

Earthquake and tsunami disasters

Comparison of the balance sheets of completely destroyed houses and victims in Fudai for the disasters of 1896, 1933 and 2011
Disaster event Completely destroyed houses Death toll source
Meiji 1896 (earthquake and tsunami) 76 302
Shōwa 1933 (earthquake and tsunami) 79 137
Tōhoku 2011 (earthquake and tsunami) 0 1
Note: The death toll for the 2011 Tōhoku disaster is calculated from the total number of dead and missing in the 153rd FDMA damage report of March 8, 2016, minus the figures for catastrophe-related deaths determined by the Reconstruction Agency (RA).

Historical tsunami experiences

Fudai was formed by the Meiji tsunami in 1896 (with a height of 15.2 meters), by the Shōwa tsunami in 1933 (with a height of 11.5 meters) and by the Chile earthquake tsunami in 1960 (with a height of 11.5 meters) , 5 meters) badly damaged. The village of Fudai developed along the Fudai River (Fudaigawa). The tsunamis it suffered from in 1896 and 1933 had advanced along this river. Together, Fudai lost 439 inhabitants in the disasters.

Construction of the Ōtanabe dike

At the instigation of the mayor Kōtoku Wamura ( 和村 幸得 ; 1908 / 1909–1997, ruled 1947–1987) the 15.5 m high and 155 m wide Ōtanabe dike ( 太 田 名 部 防潮 堤 , Ōtanabe-bōchōtei ) was built, which was completed in 1967 after 58 million yen construction costs and separates the area of ​​the aftanabe fishing port to protect the residential area behind it in the Ōtanabe district (太 田 名 部).

Construction of the Fudai Weir

Since the mayor was convinced in the early 1980s that the village would sooner or later be exposed to a 15 meter high tsunami, he also left the 15.5 about 300 m inland from the mouth of the Fudaigawa, which ran through the village m high and 205 m wide Fudai weir ( 普 代 水 門 , Fudai-suimon , also known as tsunami gate in English ). It was completed in 1984 after a construction cost of 3.5 billion yen and was intended to seal off the estuary in the event of a tsunami. The topography of the village of Fudai, which is surrounded by rock walls with a narrow opening to the sea, was an essential factor that made the construction of such a high weir possible.

These two construction projects drew a lot of criticism given the much lower height of other weirs in the prefecture and the cost compared to the population.

Proof of the coastal protection structures during the Tōhoku tsunami 2011

Because of these coastal defenses, Fudai is known as the site of a successful tsunami countermeasure strategy that protected the village from the 2011 tsunami.

The tsunami triggered by the Tōhoku earthquake on March 11, 2011 towered over the weir by two meters, but the height of the weir and dyke ensured that in Fudai, in contrast to other communities, there were neither deaths nor destruction or Damage to residential buildings occurred. Only one person was missing and damage was recorded to 16 public and 158 other non-residential buildings.

The 17 m (according to other information: 20 m) high tsunami flooded the Fudai weir, but could only penetrate a few hundred meters behind the weir. Most of the village with the settlement center, including the evacuation buildings (various schools), remained protected. Without the tsunami guard, the 2011 tsunami would have damaged the center of the village.

Inundation heights of 8.4 m and 8.9 m were measured in the area of ​​the Ōtanabe fishing port, and two run-up heights were determined on the coastal dike with 10.6 m and 12.4 m. While the area of ​​the fishing port outside the Ōtanabe dyke suffered severe damage, the residential area in the Ōtanabe district behind it was completely protected from the destructive force of the tsunami by closing the rotary tide gate in good time before the tsunami's arrival and showed only insignificant damage.

traffic

Important highways to Fudai are the national road 45 to Sendai or Aomori , whereby the section between Fudai and Iwaizumi is referred to as the Sanriku-Kita-crossing road ( 三 陸 北 縦 貫 道路 , Sanriku-Kita jūkan dōro ). There are also prefecture roads 44 and 202 in the municipality.

Fudai is connected to the rail network via the Kita-Rias Line (North Rias Line) operated by the Sanriku Tetsudō railway company. This leads to the main train stations of Miyako or Kuji . The stops in Fudai are Fudai ( 普 代 駅 , -eki ), Shiraikaigan ( 白井海 岸 駅 , -eki ) and Horinai ( 堀 内 駅 , -eki ).

education

In Fudai there is a primary school and a middle school, both on the edge of the town center in the immediate vicinity of the weir.

Town twinning

In October 1985 Fudai closed a "40 ° -Nord-Gemeindeefrundschaft" ( 北緯 40 度 友好 町 村 , hokui 40-do yūkō chōson ) with Kotooka , since both communities were on the same latitude. With the incorporation of Kotooka to Mitane on March 20, 2006, this relationship dissolved.

The tsunami hazard map with its tsunami flood information is based on three tsunami simulations (1st historical Meiji-Sanriku tsunami, 2nd historical Showa-Sanriku tsunami and 3rd predicted Miyagi-Oki earthquake tsunami). The map of the Kokudo Chiriin (国土 地理 院, Geographical Survey Institute = GSI) has been created on a scale of 1: 25000 and is intended for printing on A3 paper . The damage prediction study was carried out by Iwate Prefecture in 2003 and 2004.
