Office KTK was established in Onomichi-city, Hiroshima in Japan in 1977 as a translator's and interpreter's office for SMEs. Since then we have served for many companies, groups and individuals with its business policies of contribution to internationalization, natural environment and local communities.
KEC Inc., the predecessor of Office KTK, has been an electronic and chemical technology development company and it worked on developing the electricity saving technologies and the devices (named SOD) between 1994 and 2012. It won Energy Conservation Award in 1997 as the smallest company ever, and the technology has been transferred to NTT-AT.
The SOD also has received two other prominent awards, making us a triple awards winner.
This SOD technology has now been applied to Internet SOD as IoT (Internet of Things) as well. （Introductory video at the exhibition）

The expression "Sustainable Development Goals" (SDGs) has been often used these days, but our office, OFFICE KTK, was already working on SDGs in 1994 with the development of energy-saving technology.
SOD was calculated its environmental impact using the life cycle assessment method and also evaluated for its environmental impact reduction effects by itself, which led to Type III EcoLeaf environmental label certification as the 3rd one in Japan,
