Oyama Nature Park is a beautiful natural area located near the summit area (elevation 317m) of Oe Town, Yamagata Prefecture. The highlight of this park is the annual "Oyama Nature Park Lily Festival," held from late May to early June. During this period, approximately 60,000 Hime-sayuri (small lilies), a rare species typically found in southern Tohoku and parts of Niigata, bloom in spectacular fashion. A tourist information center is available on-site, where visitors can often find brochures and local souvenir-related information.
The park is maintained to preserve and showcase the unique natural environment of Oe Town. It serves as a vital habitat for the Hime-sayuri lily, making it a significant site for local biodiversity. Through events like the Lily Festival, the park plays a crucial role in celebrating and communicating the beauty of the changing seasons and the natural heritage of the region.

The primary attraction is the seasonal blooming of the Hime-sayuri lilies. Between late May and early June, the sight of 60,000 lilies creates an unforgettable landscape. Visitors can also visit the information center to collect local travel pamphlets and gain deeper insights into the area's natural features. The ability to observe the growth and blooming stages of these plants in their natural habitat is a unique feature of this park.
The best time to visit is during the peak blooming period of the Hime-sayuri, which falls from late May to early June. This coincides with the "Oyama Nature Park Lily Festival." Since the blooming status can vary depending on weather, it is highly recommended to check the latest updates on the official Oe Town website before your visit to ensure you catch the peak beauty.
Visitors can enjoy leisurely walks through the natural scenery. During the Lily Festival, the experience is further enriched by potential guided tours provided by the information center. You can also browse local goods and products sold on-site. It is a perfect place to connect with nature and witness the seasonal transformations of the landscape.
Nearby, you can explore other natural facilities such as the Onuma Lakeside Campground and the Sagae City Ikoi no Mori. Additionally, local cultural spots like the Oe Town Yamazato Exchange Center and "Masa-be" are located in the vicinity. These areas can be easily integrated into a larger itinerary for a full day of exploring Yamagata's natural and cultural charms.
As the park is a natural environment, please wear comfortable walking shoes and clothing suitable for light hiking. Please note that cash is often required for purchasing goods at the information center. To ensure a successful trip, we recommend checking the official Oe Town website for the most current information regarding flower status and event details.
