Forest Seawall

A forest seawall at Toyohashi Plant

Sango's Toyohashi Plant is located in Akemi-cho in Toyohashi city, an area where the Prime Minister's Cabinet Office has announced that a tsunami of up to 3.2 meters is predicted in the event that an earthquake were to occur in the Nankai Trough. In order to restrict tsunami damage to a minimum, we have planted trees on mound around the perimeter of the plant, creating a seawall of trees.

How Sango tree planting started

In 2006, the former site of Sango's Nagoya Plant and the birthplace of Sango was reborn as ECO 35; this was also the beginning of Sango's Tree Planting activities.

The words of Dr. Akira Miyawaki struck a chord with Sango's president.

The start of the Sango Tree Planting was inspired by a television program featuring Dr. Miyawaki, which President Tsunekawa happened to see. In the NHK program, "Taking Pleasure in Knowledge", a story was told about tree planting at Nippon Steel which took place in 1970. President Tsunekawa was impressed by the seriousness with which Dr. Miyawaki undertook this endeavor, when, as a pre-requisite for providing guidance in creating a wooded area on the periphery of the company's Oita Steel Factory, Dr. Miyawaki said, "I want you to take this project seriously, so if these trees wither and die, please stop the fires of your furnaces". For a steel maker, stopping the fire of a furnace would be like having an automobile maker stop his stamping or welding operations. Thus, with his deep impression of Dr. Miyawaki' s determination to protect the people of the local community, President Tsunekawa traveled to Yokohama to visit Dr. Miyawaki' s office in February of 2006, where he asked Dr. Miyawaki for his guidance in creating wooded areas at Sango.

The teachings of Dr. Akira Miyawaki

Over the span of 60 years, Dr. Miyawaki has planted 40 million trees in Japan and abroad. Planting trees is the same as bringing up a child. He advocated the creation of 'real' woods, instructing us to hold clear principles and remain devoted to them, even when up against a harsh environment. Sango is now carrying out activities aimed at creating 'real' woodlands.
