International Cooperation

Johkasou is a unique system of decentralized treatment systems born in Japan. There are various types of johkasou with different treatment performance levels, so they can be applied to both developing and developed countries for sustainable decentralized treatment at a low cost. JECES has held seminars on johkasou systems for visitors from overseas. JECES has joined international cooperation projects for transferring johkasou technology to other countries. JECES expects international cooperation with organizations of other countries in decentralized treatment technologies.
