The park was established to preserve the natural valley environment and the agricultural landscape of old Yokohama.
It contains a designated 'Manabu-no-mori' (Learning Forest) designed for environmental education programs.
The park includes an original preserved farmhouse that illustrates the traditional lifestyle of the local rural area.
The reservoir acts as a central focal point for local wildlife, particularly migratory water birds during winter months.
The park maintains a 'Small Animal Friendliness Area' where visitors can interact with guinea pigs and other domesticated animals.
Children's Nature Park, locally known as Kodomo Shizen Koen, is a sprawling 39-hectare green space anchored by the Oike reservoir. The park landscape features a designated orchard area planted with numerous cherry and plum trees that bloom in early spring. It functions as a preserved woodland with walking trails that connect hilly terrain to the central water basin. The site incorporates a small animal interaction area, including a petting zoo section for children. Several suspension bridges and wooden boardwalks cross over the marshy sections and streams leading to the reservoir. The vegetation consists of secondary forest typical of the Yokohama hills, providing habitat for local bird species. Visitors can observe seasonal changes ranging from plum blossoms in February to cherry blossoms in late March and April.

Wear sturdy walking shoes, as the terrain consists of unpaved forest trails and frequent incline changes.
Bring insect repellent during the summer and early autumn months to manage mosquitoes in the wooded areas.
Use the map boards located at the main entrances, as the trail network is extensive and easy to misnavigate.
Do not attempt to navigate the steeper mud paths immediately following heavy rainfall, as they become very slippery.
Animal interaction areas are typically closed on Mondays; if Monday is a holiday, they may close on the following day instead.
Take all trash home as there are limited public waste bins; do not feed wild animals in the forest areas.
