In 2018, under the guidance of Professor Takada of Tokyo University of Agriculture and Technology, started research on microplastics.

In 2018, a preliminary survey will be conducted using white sardines off the coast of Kisarazu in Tokyo Bay and Oikawa in the middle reaches of the Tama River (near Tama Ohashi), and the digestive organs of the samples will be removed and immersed in a 1 mol sodium hydroxide aqueous solution. Succeeded in an experiment to dissolve the protein content of the digestive organs and remove microplastics, and conducted a full-scale investigation from the following year.

・ Microplastic pollution survey using Oikawa as a marker in the downstream area of the water retreatment center water distribution port in the middle reaches of the Tama River.

・ A microplastic pollution survey was conducted using Oikawa as a marker in the downstream area of the water retreatment center water distribution center in the middle reaches of the Tama River. Investigate at each point of the center. Japan's first survey announcement in the high school biology club

・ Microplastic pollution survey using mountain stream fish such as char, yamame trout, and amago as markers in the entire Taba River system at the headwaters of the Tama River with the full cooperation of the Tabayama Fisheries Cooperative.

・ The survey locations are near the Tamba River main stream Fudo Waterfall, near the Sanjo River, near the Ushiroyama River No. 1 Dam, near the Yanagisawa River Ochiai Campground, upstream from the encounter with the Yanagisawa River on the Takahashi River, near the Ichinose River Main Stream, near the Ichinose Nakagawa Dam, and near the Ichinose Nakagawa Dam. Microplastics are detected from specimens captured in all places such as the upstream area, near the entrance of the Ichinose Nisshin River Kasatoriyama mountain trail. It turned out that all the samples were contaminated, including the mountain stream fish in the headwaters where there are no settlements upstream.

・ Former microplastic pollution in the presence of Hidaka City Council members at the request of Hidaka City citizens and Saitama Nishi Fisheries Cooperative in the upstream area of the drinking water intake near Kinchakuda, Hidaka City, which is the upper reaches of the Koma River, which is the Arakawa River system. Conducted a survey. Detects microplastics from all captured Oikawa, Dace, and Kawamutu specimens, etc.

・ In order to create a true forest, the correct knowledge and enlightenment activities of the pollinator "Japanese honeybee" and the large trees required for the Japanese honeybee's nest are decreasing, so a nest box will be installed in the forest.

・ We are planning an event to think about environmental conservation with local children and the production of "insect inn" as a nest of "flower bees" which are pollinators other than Japanese honeybees.
