Overview

Onneto means "old swamp" or "large swamp" in the Ainu language. It's a barrier lake formed when an eruption of Mount Meakan-dake dammed the Raowan River at its western foot. Japanese fire salamanders and crayfish inhabit the lake. The lake's surface color changes from clear blue to emerald green to dark blue depending on the season, weather, and viewing angle, earning it the nickname "Five-Colored Lake." On calm days, it perfectly reflects Mount Meakan-dake and Mount Akan-fuji, offering a truly magnificent view. A wooden observation deck provides panoramic views. Well-maintained walking trails wind through the surrounding primeval forest, allowing visitors to immerse themselves in untouched nature. Onneto's charm extends beyond its natural beauty to its rich history. The surrounding area boasts various historical sites, including hot springs, waterfalls, and former mine sites, allowing visitors to experience nature and history simultaneously. We recommend allowing ample time to fully explore Onneto at your own pace.
