Development and Park Layout
The park was developed during fiscal years 1974 and 1975 and opened in spring 1976. The Nishigawa Canal, which flows through central Okayama, was excavated during the Keichō era (1596–1615). Greenways were subsequently created along both banks, transforming the canal into an attractive public space.
The greenway consists of three sections, arranged from south to north: Edagawa Greenway Park, extending approximately 0.5 km; Nishigawa Greenway Park, approximately 1.0 km; and the Upper Nishigawa Greenway, approximately 0.9 km. Each section was developed at a different time, creating a continuous green corridor through the city with a total length of about 2.4 km.
Restoring Nature in the City
The park was created to restore greenery that had been lost through urbanization and to improve the quality of the urban environment. The Nishigawa Canal originally supplied water for everyday use, but during the Meiji era (1868–1912), it became dedicated to agricultural irrigation. As Okayama expanded, the surrounding green spaces diminished, making environmental improvements increasingly necessary.
Until the early Shōwa era (1926–1989), the canal was closely connected to the daily lives of local residents, who used its banks for washing and recreation. However, rapid urban development brought a decline in greenery and worsening urban pollution. The greenway project sought to restore a more pleasant environment while preserving the canal as an important feature of the city.
Design and Landscape Features
Stretching for approximately 2.4 km, Nishigawa Greenway Park offers a variety of landscapes along its route. Roads and bridges divide the greenway into sections ranging from several dozen to more than one hundred meters long. Each section has its own design theme, allowing visitors to encounter different scenery as they stroll through the park.
The total development cost was approximately 225 million yen. Donations, including trees contributed by local residents, accounted for around 60 million yen, reflecting the community’s involvement in creating this shared green space.
Facilities and Plantings
Facilities throughout the park include pergolas, waterside terraces, a waterside plaza with a clock tower, a fountain plaza, flower-bed plazas, and stone-paved terraces. These features provide places to pause, relax, and enjoy the scenery beside the canal.
Dense belts of greenery have been planted along the road-facing side to screen the traffic, while the use of medium-height trees has been kept to a minimum in selected areas. Near the water, plants such as deutzia, hydrangeas, and Japanese irises help create a more inviting waterside environment.
How the Greenway Took Shape
A greenway development plan was drawn up in 1972. The original proposal aimed to reduce the width of the roadway on the eastern side of the Nishigawa Canal and create a pedestrian-only greenway. However, the plan faced opposition from local residents and merchants. A compromise was eventually reached, allowing the eastern roadway to be narrowed while making room for landscaped areas.
This process led to the creation of approximately 1 km of greenway, divided into several sections featuring flower-bed plazas, waterside spaces, and sculptures. Further development extended the greenway southward and into the upper reaches of the canal, completing the 2.4 km route through central Okayama.

Edagawa Greenway Park
Located south of Nishigawa Greenway Park, Edagawa Greenway Park was completed in 1979. This approximately 500-meter-long section features ponds, a waterside plaza, and a fountain plaza. Around 7,500 trees were planted to create a lush environment for walking and relaxation.
The Upper Nishigawa Greenway
Landscaping efforts also transformed the upper reaches of the canal into a greenway. Together, the three sections form a continuous north–south corridor through the city, offering residents and visitors an accessible place to enjoy nature within the urban environment.
National Urban Greening Fair
In 2009, Nishigawa Greenway Park served as a supporting venue for the 26th National Urban Greening Fair. The event welcomed many visitors and helped introduce the park’s distinctive combination of water, greenery, and urban design to a wider audience.
