What makes it special
About Oshirogawa Valley
- For Beginners: The walk to Senga-fuchi (approx. 15 mins from parking) is the easiest way to enjoy the stunning emerald green waters. It is perfect for families and those seeking a light stroll.
- For Experienced Hikers: If you aim for Jinja Falls or Fudo Falls, professional hiking boots and full gear are essential. While some paths are maintained, be prepared for steep slopes and sections requiring handrails.
- Pro-Tip to Avoid Crowds: During summer vacations or peak autumn foliage, we strongly recommend arriving at the parking lot before 9:00 AM to avoid traffic and full lots.
- Ideal Itinerary: A perfect way to experience the area is to go for a hike, then relax in the nearby "Oshiro no Yu" hot spring, and finish with local treats at "Michi-no-Eki Hakushu."
