About Minami Inaga Lake
Basic Information and Overview
Minami Inaga Lake is a small lake with a circumference of approximately 501 meters and a maximum depth of 10.4 meters. Located in the former Kushigata Town area, it is now known as Kamiichino, Minami Alps City. The lake surface displays a deep green color, and the landscape surrounded by beautiful cypress forests captivates visitors.
White swans and carp swim in the lake, and in particular, a single white swan named “Hakumaru-kun” has become a beloved local presence. The lake rarely freezes completely even in winter, allowing visitors to enjoy the scenic reflections on the lake surface throughout the year.
Two Inaga Lakes
In fact, there are two Inaga lakes: Minami Inaga Lake and Kita Inaga Lake. Minami Inaga Lake is located along Prefectural Road 108, making it easily accessible with many visitors. In contrast, Kita Inaga Lake is off the main road, making it easy to overlook, but it is recommended for those seeking a quieter atmosphere.
Both lakes have well-maintained walking trails surrounded by trees, allowing visitors to feel nature up close while walking around the lake.
The Charm of Minami Inaga Lake Through the Seasons
Spectacular Autumn Foliage Season
Minami Inaga Lake attracts the most visitors during the autumn foliage season. From late October to early November each year, the trees around the lake turn red and yellow, creating a wonderful landscape through the contrast with the lake’s deep green color.
During the autumn foliage season, the “Ecopa Inaga Lake Autumn Foliage Festival” is held, with the 2025 event scheduled for November 1 (Saturday) to 3 (National Holiday). During this period, local specialty products are sold and various events are held, creating an even more lively atmosphere.
Walking along the trail that circles the lake allows you to enjoy the foliage from various angles. The autumn leaves seen in the soft morning light are particularly special and ideal for photography.
Lush Green Summer World
During summer, the Minami Inaga Lake surroundings transform into a world filled with green. With an elevation of approximately 890 meters and proximity to water, it remains relatively cool and comfortable even in mid-summer. While the city swelters in extreme heat, this location enjoys refreshing breezes, making it an ideal refuge from the heat.
Walking along the lakeshore surrounded by dense green vegetation offers forest bathing benefits and provides mental and physical refreshment. Rental boats are also available, offering a spectacular view of the green landscape from the lake itself.
Serene Winter Beauty
Winter at Minami Inaga Lake is a season where visitors can fully appreciate its serene beauty due to fewer visitors. While the city areas may be free of snow, snow remains along roadsides and in shaded areas as elevation increases, creating a distinctly winter landscape.
The trees around the lake have shed their leaves, making the lake surface feel larger. In the clear winter air, the sight of the white swan Hakumaru-kun swimming gracefully on the lake’s surface becomes a signature winter scene. With proper cold-weather protection, visitors can fully appreciate the quiet nature that winter offers.
Spring Budding and New Growth
At Minami Inaga Lake in spring, tree budding and new foliage welcome visitors. In stark contrast to winter’s quiet, the landscape is filled with vitality. The lake, with increased volume from snowmelt, displays an even more beautiful radiance.
