The garden contains both Japanese and Chinese varieties of peonies, known locally as 'botan'.
Many of the peony plants on site are over 20 years old, contributing to the scale of the blossoms.
The garden is integrated into the Iwakura municipal green space area, which also hosts local vegetation trails.
During the peak bloom, the garden hosts a specific Peony Festival to celebrate the horticultural cycle.
Higashimatsuyama Peony Garden is the largest peony garden in Japan, spanning approximately 30,000 square meters. The garden features over 6,500 individual peony plants representing approximately 150 different varieties. The collection highlights the 'Shimane' style of cultivation, known for protecting the delicate blooms with straw coverings. The peak viewing period occurs during the spring when the flowers are in full bloom. The park landscape incorporates rolling hills and well-maintained pathways designed to provide clear sightlines of the garden beds. It serves as a primary site for local horticultural preservation and botanical study in the Saitama Prefecture.

Wear comfortable walking shoes as the terrain includes gentle inclines and dirt paths.
Check local bloom forecasts online before traveling, as the peak season window is often less than three weeks long.
Bring a polarizing filter if you are using a camera to manage the high contrast of the bright petals under sunlight.
Visiting outside of the late April blooming window, as the park offers little visual interest when the peonies are dormant.
The garden is only open to the public during the annual spring flowering season; it remains closed during the remainder of the year.
Do not touch the flowers or step off designated paths into the garden beds.
