MinamiSanriku is a small town in the northeastern corner of Miyagi Prefecture in Japan. Shizugawa, Togura, Utatsu and Iriya are the four districts that together make MinamiSanriku. It is famously called the “resort town” or “forestry town” for its topographic features. This region is the heart of Japan’s seafood industry. The population of the town was 17,429 in 2010 according to the demographic survey, which is almost 12% lower than the year 2000.

The 2011 earthquake in the Pacific coast of Japan followed by the tsunami destroyed the region leaving many shelterless and family less. The city lost almost half its population. It took years for the people of MinamiSanriku to rebuild their lives. As the region has a great history of earthquakes and tsunamis the traditional beliefs and practices and the physical help by other Japanese cities helped them rebuild their city for the future.

Geographic Character 

MinamiSanriku City is a harmony of ocean and mountains. Approximately 70% of the city is forest land. The coastline is edged with mountains that plunge into the ocean, covered with hundreds-year-old cedar trees. The favourable soil conditions in the red ion help them grow for hundreds of years. The fog and the wind from the ocean with wealthy minerals contribute to the strong and healthy trees.

Satoyama is a place in MinamiSanriku where the traditional Japanese landscape is shaped by practising agriculture to live. It is a green landscaped area with terraced rice fields. The region also has a rich history of gold mines. The natural cycle of life and an environment coexisting with organisms has been the lifestyle of Japanese people for a long time now. Satoyama has been sustaining millions of people for thousands of years despite the urbanisation and changing lifestyle. 

The mountain ridges of MinamiSanriku connect adjacent cities. Obandaira is one such preserved National forest overlooking the Ria coast, in the mountains of Tokugawa district. The magnificent grasslands, huge mountains covered with deciduous broad-leaved forest, and the panoramic view of the coast are enjoyed by the people. 

History of Disasters

MinamiSanriku has suffered from the effects of tsunamis since ancient times: the 869 Sanriku earthquake, the 1896 Sanriku earthquake, the 1933 Sanriku earthquake, 1960 the Chile earthquake and the 2011 Tohoku earthquake. 

During the 869 Sanriku earthquake around 1000 people were killed overall and the tsunami had caused extensive flooding in the Sendai plain. It is determined that the wave reached at least 4km inland destroying the town and its castle. The damage has been mapped with dated deposits of sand from the 8th and 9th centuries beneath the present town. It is closely matched with those of the 2011 Tohoku tsunami.

On June 15th 1896, the people along the Sanriku coast were celebrating the return of soldiers from the First Sino-Japanese war. The 1896 earthquake resulted in two consecutive tsunamis which destroyed 9000 houses and caused 22000 deaths overall. Most deaths occurred in the Miyagi Prefecture. As it was the practice of the fishing community to gather at the sea in the evening, that was when the tsunami hit the shore causing more deaths.

In 1933 Sanriku earthquake occurred on March 3rd in almost the same location as that of the 1896 Sanriku earthquake. It destroyed over 7000 houses along the northern coast, which was 98% of the city’s houses. 1522 people were dead, 1542 missing and 12,053 injured overall which was 42% of the city’s population. 

The Chile earthquake during 1960 caused a tsunami that crossed the pacific and struck Shizugawa with extensive damage. It resulted in the construction of harbour walls for two-storey height in 1963. 

The 2011 earthquake caused tsunamis that were more deadly and destructive than the earthquake. The unexpected surge of water killed a thousand in Minami and left 9500 missings. The harbour wall proved ineffective. Even the designated tsunami evacuation sites were hit by the wave. Almost 846 children were left orphaned but safe in the school as it was a working day. Almost no structure survived the tsunami waves for its intensity. The city’s hospital was one of the few structures left with minimal damages, yet most of the patients did not survive.

It is believed that the people of MinamiSanriku lived in the mountains thousands of years ago for their safety from natural disasters, then they moved towards the fertile inlet of the Pacific Ocean. The settlement became permanent in years and grew between the two rivers flowing from the mountains. After the 1960 tsunami, the schools were built on high ground which saved children in the 2011 tsunami. Schools were also used as evacuation centres.

Rebuilding the future 

The disaster had a huge impact on the demographics, the shrinking population with 12,500 people and people moving to big cities. A damage characteristic and field survey of the 2011 tsunami has concluded that soft countermeasures like experience and education to reduce loss of life are needed. Hard countermeasures like properly designed coastal structures for survival are to be designed. The combination of both is necessary for optimising the outcomes of the disaster when reconstruction is considered for better countermeasures in the future.

The reconstruction planning authorities decided only commercial buildings to be built in the old townsite and residences to be built on higher grounds. MinamiSanriku’s memorial park was built around the disaster management centre, whose metal skeleton stands after the wave. 

43 workers died after their constant effort warning and evacuating people from the city. Only two of the workers were able to make it clinging to the antenna of the building. It stands as a painful memory and the hard work of the people who cared for their loved ones. The site also has the foundation of buildings that were in the region as nothing was left to preserve as a memory.

The sun sun shopping village is connected to the memorial through a pedestrian bridge crossing the river, which stands as a symbol of recovery from the 2011 earthquake and tsunami. It houses dozens of shops and eateries serving traditional dishes for tourists and visitors. The permanent structure was designed by Kengo Kuma, an architect from the region and opened in 2017.

Asahi kindergarten was designed by Tezuka architects in the year 2016. The original kindergarten was destroyed in the 2011 tsunami. The use of cedar trees killed during the tsunami planted after the 1611 tsunami would bring the spirit of the lost town. It would help the children and the people reaffirm hope.
