Like many small rivers in cities, Xichuan became a beautiful scenery after some rectification, otherwise it would be a smelly river. Okayama started to rectify Nishikawa in 1974 and was completed in 1982. A green corridor was built on both sides of Nishikawa, the Nishikawa Greenway Park, with a total length of 2.4 kilometers. This project also made Okayama the first in Japan. "Green City Award".
Across the street from Okayama station, there is a river at one stop. Nishikawa Green Road Park is the green area on the banks of the river. The bridge is a statue of a fat little boy, and a fountain is erected on the river. Look at the pictures online, the river is full of cherry blossoms in spring, that season should be beautiful.
