Since the beginning of the Edo Period, ships have sailed Shingasi River transporting people and goods and it also served the cultural role of connecting Kawagoe and Edo closely. However, such a role was weakened along with the opening of the railways. Also the volume of the river water became insufficient due to river improvement work for flood prevention. Thus, transportation by ship was discontinued in the beginning of the Showa Period.
Today, there is an attempt to revive transportation by ship on Shingasi River to promote tourism, and a social experiment of transportation by ship for tourists is being conducted in the water area near streets with the atmosphere of Edo in central Kawagoe City.

Itako City, together with Sahara City located in the south of Tone River, flourished as a transshipping port to convey products of each clan of Oshu to Edo.
Today we can enjoy attractive scenery unique to a "riverside district" as a tourist town typified by small ships coming and going on the water and boatwomen.
Itako boating station with a 2,000m course using the straight river area is highly evaluated as a waterfront for social interaction. It won the "Handmade Hometown Award" in 1986.

Nishitakase River running through Kyoto City was opened as a canal for transportation by water. Later, it was used to discharge the water for textile dyeing such as Kyo Yuzen printing and the color of the river water changed daily and the water quality deterioration was serious.
Under the circumstances, the contamination was reduced and ozone treatment facilities were installed in 1997.Since then the color of the river and foam formation have been improved dramatically and the water environment of this river has greatly recovered. In addition, this river was selected as a "Limpid Stream Renaissance II project river" and because efforts were made to create an environment for water amenities and improve the water quality, a river environment suitable for a stroll in Kyoto has been recovered.

For Ayase River, which was recorded as the worst river in terms of water quality for 15 consecutive years, a project was conducted to channel the water of Ara River upstream as part of "Limpid Stream Renaissance II" (a water environment improvement emergency action plan). This project won the Japan Society of Civil Engineers' Environmental Award in 2001 as Japan's first project using the tunnel upper part for subways and the lower part for a river water conduit.

Furo River, running through Saitama Prefecture, was once called "Toshitorazu (meaning unaging) River" because the main water source was a spring that dried up in winter and the flowing water did not see the old year out.. However, a large quantity of living drainage was discharged into the river due to the population increase in the basin and the river was named the most contaminated river in Japan and such a disgraceful situation was continued in the past..
Now, the"basin sewage project for Furo River water quality environment conservation measures" are being conducted to recover the water environment by resolving the sewage-treated water into Furo River. Moreover, efforts are being made to conserve and regenerate the water environment through water environment improvement projects such as "Limpid Stream Renaissance 21" and "Limpid Stream Renaissance II".

Concerning Yanase River, a tributary stream of Shingashi River, running through Saitama Prefecture, the water quality was extremely deteriorated in the decade starting in 1975 because of the rapid increase of the population during the high-growth period. However, the water quality has been improved gradually as a result of the construction of a sewage system. In 2006, a river environment improvement project was started based on the “Yanase River basin water circulation master plan”. To solve water problems related to river conservation, water utilization and the water environment, river restoration activities are being conducted under cross-sectional cooperation of not only the river administrator but also the administrative agencies concerned.

In Komaki River, the water quality was deteriorated by urbanization and the river was named the "dirtiest river in Yamagata Prefecture" each year from 1996 to 1999. People in this area suffered from the serious deterioration of the water environment.
Under the circumstances, local residents voluntarily established "a group to clean up the Komaki River of Sakata City" and are conducting purification activities earnestly. As an approach to utilize the existing agricultural water and the agricultural facilities to improve the waterfront environment, a project to flow the purified water (ambient water) from Mogami River to Komaki River by changing the place where agricultural water is discharged started in 2007 for the first time in Japan. Thus the water quality has been improved.

In the "Azami-no-se" area of Matsuura River running through Matsuura County of Saga Prefecture, people have long suffered from flood damage. Therefore the retarding method has been adopted as the flood countermeasure instead of building embankments in this region and resident-participation projects to recover organisms in the valuable river environment and regenerate the contact between people and organisms are being promoted. As a result, a traditional fishing method has been revived and children have begun to play by the riverside again. In this way, the connection between people and nature has been regenerated.

Shinji Lake is located in the eastern area of Shimane Prefecture. It is a typical brackish lake in Japan together with Nakaumi. Its rich nature and excellent landscape are used for fishery, sightseeing and recreation.
However, the conditions surrounding the water environment are severe due to socioeconomic activities and the changes in lifestyle in the peripheral basin, thus water quality conservation is an important issue to be solved.
Under the circumstances, a “lake water quality conservation plan” to conserve the water quality has been drawn up and various water quality improvement programs are being conducted. In addition, activities to plant and grow reeds have been promoted by industry - government - academia - private collaboration including local elementary school students and the pollution load in the basin is steadily decreasing.

In Yodo River running through Osaka, earth and sand are deposited around the spur dike, which was built to maintain the course for cargo ships, and many pools and valuable habitats for organisms have been created. However, because the water level fluctuation has decreased as a result of the construction of Yodo River Great Weir downstream, its environmental impact on Johoku pools is a concern.
For this reason, an experiment toward the recovery of the pool environment is being conducted by improving the operation of the weir to increase the water level fluctuation and improve the in-pool water quality.
