On July 18, as part of its nature conservation efforts, Canon implemented the Tama River Project Part II. Part I was implemented in Hamura City, Tokyo, in June.

Part II of the project took place around the Daishihashi mud flat near Daishi Bridge in Tokyo's Ota Ward. Twenty-five employees and their family members took part. The Daishihashi mud flat is one of the few mud flats still remaining on the lower reaches of the Tama River. Besides playing an important role in cleaning the waters of the Tama River and Tokyo Bay, it is also a valuable breeding ground for wildlife.

Upon gathering at the mud flat, the participants used test chemicals to determine the quality of the water, and discovered that, despite the lower Tama's polluted image, the waters were surprisingly clean. They then observed the organisms inhabiting the mud flat. An expert from a non-profit organization explained the distinguishing features of many different species of crab, shijimi (corbicula clam), lugworm, and so forth.

The group also picked up garbage buried in the mud, collecting 16 kg of paper and packaging, wood scraps, plastic bags, bits of metal and glass, and other refuse.

The project was a valuable opportunity to learn about natural ecosystems in the city. As one participant remarked, "It made me realize the important role that mud flats play in nature's self-purification system."
