In Japan, an onsite wastewater treatment system is known as a “Jokaso” (Joe-kah-so).
Before the Jokaso, Japan’s waterways suffered contamination due to unsatisfactory wastewater treatment being provided by basic septic systems. Polluted waterways and increasing demand for flushable toilets helped push the industry towards a higher standard of onsite wastewater treatment. The Japanese Government implemented standards that forced manufacturers to upgrade and develop their treatment processes and systems. The result was a single compact onsite wastewater treatment system that treats all household wastewater to a quality safe enough to discharge directly into the stormwater drainage system. (unlike Australia, Japan do not have the physical space for a Land application area.)
Fuji Clean Co Ltd. was established in 1961 and have continuously developed their range of wastewater treatment products over the past 50 years. To date FujiClean have installed over 2 million Jokaso and are the industry leader in Japan with a market share of 34%. Now operating globally (Asia, Australia, USA & EU) FujiClean are working towards providing everyone with access to the most reliable & cost effective system for onsite wastewater treatment. In 2006, the Japanese Ministry for Environment reported that nearly 11 million citizens were being serviced by Jokaso technology in Japan. As a market leader FujiClean continue to install 50,000+ systems per year.
