As part of the "Johkasou Day" related events, the "Johkasou Day" Executive Committee aims to promote the need for johkasou, which is an extremely effective and efficient domestic wastewater treatment facility, to the public. Every year, we solicit slogans that appeal to everyone. The winning works will be widely used in future national campaigns to popularize johkasou. We would like to invite you to apply for the slogan for the 38th "Johkasou Day".
