Sunflower Hill Park, locally known as Himawari no Oka Park, is a large public space in Ono City featuring extensive flower gardens that rotate seasonal blooms throughout the year. The park's centerpiece is a massive wooden playground area containing large-scale climbing structures and slides designed for children. A prominent feature is the Kanryu-ji temple-inspired pagoda and the flower clock, which serves as a landmark within the grounds. The park hosts vast fields of sunflowers during the summer months, while spring offers tulips and poppies. It is designed with broad walking paths and open green spaces suitable for picnics and families. The facility integrates agricultural themes with recreational amenities, including a local produce market on-site.

Bring a picnic blanket as shaded seating areas can be occupied quickly during peak bloom seasons.
Visit the on-site market early if you intend to purchase local produce or freshly baked bread, as items sell out.
Sun protection is essential, as the expansive flower fields offer very little natural shade.
Visiting during the heat of midday in July and August without proper sun protection.
The park remains open year-round, but specific flower displays are seasonal; the on-site market is typically closed on certain weekdays.
