The park is located on the site of major historical flood control works, known as the Horeki River Improvement Project.
It is technically part of the national government-managed Kisosansen Park system, which spans multiple locations across Aichi and Gifu prefectures.
The park grounds are designed to accommodate overflow during extreme flooding events as part of the river basin management system.
The observation tower offers a 360-degree view of the delta where three major rivers merge into the Ise Bay.
The facility maintains specific zones dedicated to the conservation of local riverside vegetation and wildlife habitats.
Kisosansen Park is a vast riverside recreational facility situated at the confluence of the Kiso, Ibi, and Nagara rivers. The site serves as a flood-prevention green space that highlights the historical engineering efforts required to tame the region's complex water systems. It features a prominent observation tower providing panoramic views of the Nobi Plain. The park is home to expansive flower fields that rotate seasonal blooms, most notably tulips in the spring and cosmos in the autumn. Pedestrian pathways connect various observation decks and interactive water features throughout the river delta environment. Large open lawns are designated for public recreational use, emphasizing the integration of nature and civil engineering. The site functions as a regional center for outdoor education regarding river ecosystems.

Bring a bicycle if possible, as the extensive grounds can be difficult to cover entirely on foot.
Pack sunscreen and a hat, as much of the open park area has limited overhead natural shade.
Check the official flower blooming calendar online before visiting to time your trip with peak seasonal colors.
Do not attempt to walk to the park from the nearest station; it is too distant for pedestrians.
The park may close access to low-lying areas during high-water events or periods of heavy rainfall.
Stay on marked trails to protect local flora, carry out all trash, and refrain from feeding local wildlife.
