Rengo and Corrugated Board - A Shared History
The history of Rengo can be said to be synonymous with the history of the development of corrugated board in Japan. In 1909, Teijiro Inoue, the founder of Rengo, established Sanseisha (predecessor of Rengo), marking the beginning of commercial production of corrugated board in Japan. The origin of the corrugated board business can be traced back to the moment when Inoue, after a long and difficult effort, completed a "corrugated (dan) board (boru-gami)" product that he called "danboru." He thought that the name sounded good and was easy to remember.
