The 'Yamayaki' controlled burn has been practiced in this region for several centuries to preserve the grassland habitat.
Miscanthus sinensis is a perennial grass species that dominates the local mountainside vegetation due to historical human land management.
The grass is tall enough to completely hide an adult person standing within the designated walking path areas.
The fields are designated as one of the top locations for viewing autumn colors in the Hakone region.
Sengokuhara Susuki Grass Fields consist of extensive mountainside meadows covered in Miscanthus sinensis, also known as Japanese silver grass. The fields are recognized as one of the '50 Scenic Spots of Kanagawa.' Each year, the vegetation is cut back in a traditional controlled burn known as 'Yamayaki' to maintain the meadow ecosystem and prevent forest encroachment. A wooden pathway extends through the center of the grass fields, providing a defined route for pedestrians. The fields undergo a color transition from green in summer to a golden-beige hue as the grass matures in autumn. The site is situated at the base of Mount Daigatake, forming part of the Fuji-Hakone-Izu National Park region. The grass reaches heights of over two meters, creating a tall, dense landscape that obscures the surrounding ground level.

Wear sturdy walking shoes as the central path can be uneven and slightly sloped.
Bring a windbreaker, as the open mountainside location is frequently exposed to gusts.
Stay strictly on the designated wooden pathway to protect the sensitive grass environment.

The fields are typically closed during the spring season for the annual controlled burn event.
