JBL is not officially represented in Japan, but a lot of Japanese Koi breeders work with JBL water tests and JBL Koi food. When Kiyoko Fujita, editor-in-chief of Rinko, Japan's largest Koi magazine, saw the JBL mobile phone water test in action at the Yamamatsu koi farm, she became curious. At the next All Japan Koi Show in Tokyo she visited the JBL booth and had the test explained to her in detail. The current issue of her magazine Rinko now includes a comprehensive report on the practical water test, which can be carried out with a mobile phone and a smart app. We wish everyone who can read Japanese a lot of fun!
