The park's lavender cultivation was established to create a signature landscape for the Fujikawaguchiko area.
Kochia bushes planted in the park shift from bright green in summer to a deep, fiery red during October.
The park is built on a volcanic terrace formed by historical eruptions of Mount Fuji.
The flower beds are managed by local community volunteers as part of regional landscape preservation efforts.
The Kawaguchiko Natural Living Center serves as a research and educational hub for local flora.
Oishi Park is situated on the northern shore of Lake Kawaguchiko, providing an unobstructed panoramic view of Mount Fuji across the water. The park is renowned for its seasonal flower gardens, including fields of lavender that bloom during the summer months and kochia bushes that turn vibrant red in autumn. A 350-meter-long floral promenade lines the lakeside, featuring various perennials and shrubs designed to frame the mountain peak. On-site facilities include the Kawaguchiko Natural Living Center, which houses a cafe and regional product shops. The park features a low-elevation walking path suitable for all mobility levels. The site is a primary location for the annual Kawaguchiko Herb Festival held mid-year. Several art installations and small monuments are dispersed throughout the grounds, often utilized as focal points for photographers. The area is subject to significant traffic congestion during peak holiday seasons and clear weather conditions.
The lakeside path near the central flower promenade provides the iconic shot of lavender in the foreground with Mount Fuji in the background.
Visit on a weekday morning to avoid the heaviest tour bus crowds.

Open daily throughout the year; no specific seasonal closures.
Stay on marked paths to protect delicate flower beds and avoid littering.
