The park is specifically designed to provide a panoramic view of Mount Hira across Lake Biwa.
The sunflower planting schedule is timed to coincide with the Obon holiday season in mid-August.
The rapeseed flowers are cultivated to bloom specifically in the coldest months of January and February.
It is one of several 'Nagisa' parks located along the Moriyama shoreline of Lake Biwa.
1st Nagisa Park is a lakeside garden located on the eastern shore of Lake Biwa, renowned for its seasonal flower displays. The park features approximately 12,000 sunflowers that typically bloom in mid-summer. During winter, the landscape transforms with around 4,000 yellow rapeseed blossoms. Visitors can view these flowers with the backdrop of Mount Hira across the lake. The site is maintained as an open-access public space. It serves as a popular photography destination for both locals and tourists throughout the year. The park layout is designed to allow clear views of the lake horizon.

Check the official Moriyama tourism website for 'flowering updates' before visiting to ensure the crops are at their peak.
Bring a polarizing filter for your camera to manage the reflection of the sun on Lake Biwa.
Wear comfortable, flat footwear as the paths can be uneven after rain.
Do not visit outside of the peak blooming windows (mid-August or late January) if the primary goal is to see flowers, as the field remains unplanted between seasons.
The fields are completely cleared and plowed between the summer sunflower season and the winter rapeseed season.
Do not step into the flower beds for photos; stay on the designated walking paths.
