The park is situated at a point where the lakebed is famously shallow, historically allowing for unique shoreline activity.
It sits on a section of the Nakasendo trail route context, connecting the historical Shimosuwa-shuku post town to the waterfront.
The location is strategically aligned to provide an optimal line of sight toward the center of Lake Suwa, which is why it is prioritized during regional firework events.
The park name 'Akasunasaki' literally refers to the 'Red Sand Point' of the lakeside.
Akasunasaki Park is a lakeside public space located on the northern shore of Lake Suwa in Shimosuwa, Nagano Prefecture. The park is distinguished by its direct waterfront access, featuring a mix of sandy shoreline and grassy areas that allow visitors to stand at the edge of the lake. It is a known site for viewing the annual Lake Suwa fireworks festivals due to its unobstructed perspective across the water. The park grounds include public restrooms, paved walkways, and benches positioned for lake observation. It serves as a trailhead and rest point for cyclists and pedestrians traveling the perimeter of Lake Suwa. The terrain is largely flat, making it accessible for casual walking and outdoor relaxation.
