Lake Tazawa

Akita Prefecture, Tohoku Region

Japan's deepest lake showcases year-round cobalt blue waters and mythical legends

Discovering Lake Tazawa

Nestled in the mountains of Akita Prefecture in northern Japan, Lake Tazawa (Tazawa-ko) holds the distinction of being the country’s deepest lake at 423 meters. Its remarkable depth contributes to the lake’s signature cobalt blue waters, which maintain their striking clarity throughout the year. The nearly circular caldera lake spans approximately 20 kilometers in circumference and never freezes, even during harsh Tohoku winters, due to its extreme depth.

The lake’s most iconic landmark is the golden Tatsuko statue, which stands gracefully on the eastern shore. This bronze figure commemorates a local legend about a beautiful maiden named Tatsuko who transformed into a dragon to remain eternally youthful, becoming the lake’s guardian deity. The statue, created by sculptor Yasutake Funakoshi, has become one of Akita’s most photographed attractions.

Lake Tazawa offers visitors a range of activities year-round. In warmer months, kayaking, paddleboarding and cycling around the lake are popular pursuits. The surrounding area features hot spring resorts, hiking trails through beech forests, and the nearby Dakigaeri Gorge, known for its dramatic autumn foliage. Winter brings opportunities for snowshoeing and enjoying the serene, mist-covered landscape.

Best Times To Visit Lake Tazawa

Lake Tazawa welcomes visitors throughout the year, with each season offering distinct experiences. Spring (April to May) brings cherry blossoms around the shoreline and mild temperatures ideal for outdoor exploration. Summer (June to August) is perfect for water activities, though it can be busy during Japanese holidays.

Autumn (September to November) is arguably the most spectacular season, when the surrounding mountains explode with vibrant fall colors reflecting off the blue waters. The contrast between the golden and crimson foliage and the lake’s deep blue creates breathtaking photo opportunities. Winter (December to March) offers a peaceful atmosphere with fewer crowds, though temperatures drop significantly and snow is common.

How To Get to Lake Tazawa

From Tokyo, take the Akita Shinkansen to Tazawako Station (approximately three hours). From the station, local buses run to the lake, taking about 15 minutes (frequency varies by season). Alternatively, rental cars are available at the station for those preferring independent exploration of the surrounding area. From Sendai, the journey involves taking the Komachi train on the Akita Shinkansen to Tazawako Station (roughly 90 minutes). The lake is also accessible from Akita city via the Akita Shinkansen (approximately 50 minutes to Tazawako Station).
