At the western end of Osegahara, the Yamanohana to Cushneck is a long moor to the east and west, sandwiched between the Suisui Forest of the Nekomata River in the north and the mountain hem approaching the south side. It is one of the most watery places in Osegahara, and is dotted with small but deep water. Many floating islands are also found. The moor plants include water-loving green moss, and the hitsugita and the black-wobober that grow in the pond. In the area along the upstream forest of the Kawakami River, there is also a community of water clusters.

The plateau opened on the northeast side of the summit of Shibutsu is Kōtenkabara, a treasure house of alpine plants such as Shinanokimbai. A paradise in the heavens coupled with the exquisite view of Osegahara spreading in front of your eyes. The mountain trail connecting Mount Shibutsu and Yamanohana was closed to traffic as this area was previously trampled and devastated, but wooden paths and terraces were now provided. In addition to the Kotengagahara, there are flower fields in several places, such as near the peaks where the Takanena Deshiko, the Hemeshajin and others are blooming, and below the Mt. Climbing has been lifted since July due to the lack of mountain trails during the remaining snow season and the danger of being easy to step into the flower garden is high.

Before the road was maintained to Hatomata Pass, the most popular course was to cross the Fujimi Pass from this Fujimi Pass into Oze. It takes more than four hours to Osegahara, so there are few people who enter the mountain. Public toilets and water stations are also installed, and about 30 are available as parking spaces.
