The area of waters in Chuo-ku is 18.3% of the entire ward, and the area ratio is the largest in Tokyo.
Due to the decline of boat transportation, the development of urban functions during post-war reconstruction and high-growth periods, and the construction of the so-called "razor dike" for flood control, there were times when people were moved away from the waterside, but in recent years the natural environment of the waterside and its functions as a hydrophilic space have been rehabilitated, and efforts are being made to regenerate the waterside space, such as the waterside space, such as the waterside space, such as the waterside space, such as the waterside space, such as the waterside space.
On the other hand, rivers such as the Sumida River, where whitefish lived in the past and enjoyed playing in the water, have been remarkably polluted for a while due to the increase in industrial wastewater due to the rapid development of industrial activities and domestic wastewater due to the progress of urbanization. However, since then, various purification measures have been implemented, and it is said that fish have been seen since the time it changed to Heisei.
Currently, in the lower reaches of the Sumida River flowing through the ward, the water quality is said to have been improved until brackish fish such as goby, mullet, and seigo live, but further purification measures and continued understanding of the water quality are desired.
On a calm Sunday in early winter, on the banks of the Sumida River in the area around Tsukuda and Tsukishima, you can see quite a few people hanging fishing lines under the soft sunshine.
Turning your eyes to the river surface, you can see the goby's "kneading fishing" (when you arrive at the fishing spot, the boatman rows the turret and runs the boat).
It is a tasteful frame reminiscent of a stylish boating in front of Edomae.
