Dear reader, 

by invitation of eihap, it is with great pleasure that, as its Executive Director, I may introduce you to the Japan Far-Infrared Rays Association (JIRA). The purpose of this introduction is that of an initial step to promote future communication and cooperation activities between the Japanese and European far infrared technology sectors.   

JIRA is an association organized by companies in Japan developing their business in the far-infrared world.

Far-infrared radiation is widely utilized in various areas such as heating, drying, room conditioning, cooking, and also medical purposes. Its advantage lies in energy controllability, energy saving, and especially high efficiency.

The association is devoting its business to promote the far-infrared industry and to protect consumers. It is the only public-service corporation in Japan.




JIRA investigates, studies and collects information about far-infrared rays devices and technologies.

JIRA disseminates related technologies.

JIRA cooperates and exchanges information with domestic and foreign organizations.

JIRA promotes products and services of their industry members.

JIRA protects the well-being of consumers in the field of far-infrared radiant technologies.




June 1990  Started as a voluntary group of Japanese companies in the far-infrared technology sector.

June 1992  Established the Japan Far-Infrared Rays Association – JIRA.

October 1996  Created an Association Mark and established a product certification system.

June 1997  Implemented the certification system for the product categories of electric kotatsu, electric ovens and gas grills.
