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 internatinalization, 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. (3D rotatable images of SODs)

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

 

Office KTK is now newly operating "i V-Chat Japanese", "Online English learning support" as the language related business, and the guest house, Tour Guide for non-Japanese and the office / shop for rent (only in Japanese) as the real estate business.
