Located on the border with Gunma Prefecture, this area is home to the highest point on Japan’s national highways. The sunrise viewed from here is truly breathtaking. *The road is closed from Yosaka parking during the winter season

Nestled among the many lakes and ponds of Shiga Kogen, Onuma Pond stands out as the largest and most striking. A short detour from the Ikemeguri Trail leads you to a quaint shrine and a charming torii gate. *Please refrain from swimming in Onuma Pond to protect the natural environment. *Inaccessible in winter, as the hiking trails are covered with snow.
