Kiso Sansen National Government Park: Japan's Largest National Government Park
A Wide-Area Park Spanning Aichi, Gifu, and Mie
Kiso Sansen National Government Park (Kokuei Kiso Sansen Kōen) is Japan's largest national government park, spanning the three prefectures of Aichi, Gifu, and Mie.
As the first base of the park, the Kiso Sansen Park Center opened in 1987 (Showa 62).
Making use of the wide space and natural environment created by the three Kiso rivers (Kiso Sansen)—the Kiso River, the Nagara River, and the Ibi River—it is a place to enjoy flowers, lawn plazas, waterside scenery, environmental learning, and seasonal events.
Rather than walking the whole area from a single entrance like a typical city park, it is a wide-area park where you choose and visit the park that suits your purpose from among multiple bases.
For this reason, travelers visiting Japan will find it easier to plan travel and time on site by deciding in advance which park to go to.
There Are 13 Parks in Total
Kiso Sansen National Government Park is divided into three districts: the Sanpa-sen District (Sanpa-sen Chiku), the Central Suigō District (Chūō Suigō Chiku), and the Estuary District (Kakō Chiku).
Within these, a total of 13 bases are open.
Each base has a different atmosphere and way to enjoy it, including parks for enjoying flowers, parks for learning about river nature, parks for relaxing on lawn plazas, and parks where you can experience the history of the waterside region.
This article introduces three of these parks that are easy for travelers to Japan to fit into their itinerary.
The three introduced are Kasen Kankyō Rakuen (River Environment Park), 138 Tower Park, and the Kiso Sansen Park Center.
