Oike Springs

The Oike Springs in Asono offer a serene escape into nature, recognized among the nation’s premier waters for their exceptional purity and mineral richness.

Situated at the northern foot of Mount Kurodake within the eastern reaches of the Kuju Mountain Range, the Oike Springs serve as a primary source for the Asono River. This pristine water travels through deep subterranean layers for months, or even years, naturally filtering through the earth to emerge enriched with a sophisticated balance of calcium and essential minerals.

The landscape is a sanctuary of seasonal elegance. While the lush verdure of spring and the vivid tapestry of autumn are the most celebrated times to visit, the winter months offer a quiet, understated charm. During this season, the fallen leaves reveal expansive views of the crisp blue sky through the architectural silhouettes of the trees, a peaceful “hidden gem” experience for the discerning traveler.
