Dokko Marsh: Emerald Jewel of Zao

Dokko Marsh, also known as Dokko-numa, is a captivating natural attraction nestled in the Zao Central Highland of Yamagata Prefecture. Situated at an altitude of approximately 1,400 meters, this small marsh is renowned for its mesmerizing emerald-green waters, which shift in hue depending on the sunlight. The name 'Dokko' translates to 'swamp,' but the clear, bright waters are anything but swamp-like. Formed within a volcanic crater, the marsh is surrounded by lush beech forests, offering a serene and picturesque setting for visitors. The vibrant colors of the water create a striking contrast with the surrounding greenery, especially during autumn when the foliage turns into a tapestry of reds and yellows. The marsh is relatively small, with a circumference of about 350 meters, making it easily accessible and explorable. Dokko Marsh is a popular spot for mountain climbers and hikers seeking a peaceful retreat. The well-maintained walking courses around the marsh provide opportunities to immerse oneself in the beauty of the Zao Central Highland. Visitors can relax on the shores of the marsh, enjoying the tranquility and fresh air. The Zao Chuo Ropeway offers convenient access to the marsh, making it an easy destination for those who may not be confident in their physical strength.
