Combining our manufacturing plant with a forest

In 1990, HIOKI moved its Head Office and plant from the town of Sakaki to their current location in the city of Ueda.

In 1988, two years before that move, all HIOKI employees came together to participate in the HIOKI Forest Hills afforestation project, in which they planted some 60,000 seedlings on a site with a perimeter of 1.2 kilometers in an effort to address the environmental damage that would be associated with the relocation.

Under the guidance of Professor Emeritus Akira Miyawaki of Yokohama National University, participants in the project, which served as an experiment in restoring the type of local forest that existed in Ueda before human interference, planted 40 species of trees that were indigenous to the Shinshu region, including Quercus myrsinaefolia, Japanese zelkova, and konara oak.

In the years since, tree-planting efforts by new employees have brought the total to about 84,000 trees.
