Origins of Sengokuhara Susuki Grassland: Edo Thatch Fields to Scenic Landmark#
The vast grasslands of Sengokuhara, spanning approximately 18 hectares, were originally developed during the Edo period as a communal "kayaba" (thatch field). Local villagers harvested the tall grass (kaya) to thatch traditional farmhouse roofs and use as feed for cattle and horses.
With post-war lifestyle modernizations and the decline of thatched roofs, the grasslands faced the risk of ecological succession turning into shrubland and forest. To protect this cultural landscape, local residents revived the traditional spring "Yamayaki" (controlled grassland burn-off) in 1989. Held every March, Yamayaki eliminates invasive weeds and old thatch, fertilizes the soil with ash, and allows vibrant new silver grass shoots to sprout, preserving the golden autumn scenery for future generations.
"Oyado Gourmet": Specialty Dishes by Master Ryokan & Hotel Chefs#
The festival's signature culinary attraction is "Oyado Gourmet," featuring exclusive pop-up stalls operated by chefs from Sengokuhara's renowned ryokans and luxury resort hotels. Attendees can savor fine-dining dishes—usually reserved exclusively for overnight guests—in a casual, accessible festival format. Menus feature local branded pork, seasonal autumn vegetables, and artisanal desserts that consistently draw long, eager queues.
Geisha Bar & Traditional Performing Arts on Stage#
Visitors can experience authentic Hakone heritage at the "Geisha Bar," hosted by geishas from the Hakone Yumoto Geisha Association. Geishas in elegant kimonos serve beverages and present traditional dance performances on the special stage. The festival also features live jazz, acoustic music performances, and classic festival game stalls for children from afternoon to evening.
Spectacular Finale Fireworks Illuminating the Autumn Sky#
As the festival reaches its climax shortly before 20:00, vibrant autumn fireworks illuminate the night sky. Echoing across the 650-meter-high plateau, the thunderous booms and shimmering light canopy deliver an unforgettable emotional finale.
