Japanese rebuilding horticulture after tsunami

Who doesn’t remember the horrible pictures and videos of the earthquakes and the follow up tsunami in Tohoku Japan in March 2011? The Tohoku earthquake, as the Japanese call it and tsunami that followed left around 16,000 people dead and many more displaced without housing or job-site to go to. The Japanese started immediately making plans for rebuilding the region there is still a lot to do, but they are going strong.


Clean up teams are still working in the area collecting rubbish and garbage. The total area that has to be cleaned up is around 23,600 Ha which is a little less than 20% of total area of the Netherlands. This is going in quite an efficient way. It’s not only the visible things that needed to be cleaned up also the soil is quite contaminated with the salty water from the sea. Just a friendly reminder the EC level of sea water is around 54. It’s not possible to grow rice or strawberries on these soils before they are cleaned up.

As there is quite some strawberry production in Yamamoto-cho in Miyagi, the Japanese government decided to build a new research station called High-tech Professional Research Facility. Advanced researches for tomato and strawberry are taking place in this modern greenhouse of 7,200 m2. Several national and public research institutes, universities and private companies form a consortium to conduct researches together. Research goals by 2017 are to improve production and quality of the products, reduce production costs and improve profit of farm management. The first phase of the greenhouse construction was done by one of the Japanese leading greenhouse builders Ishiguro Nozai who not only built the greenhouse but also supplied the irrigation, cooling and heating systems. The computer controls for this project were delivered by Hoogendoorn which installed an iSii computer for complete control of the greenhouse.

The Japanese users are very happy with the system as it is easy to operate and Ishiguro has developed some very handy visualizations so a good understanding of all the processes going on in the greenhouse is easily achieved.
