The park's name, Tsutsuji no Oka, translates literally to 'Azalea Hill'.
The massive azalea collection includes both Kurume and Hirado varieties.
The landscape architecture utilizes the natural slope of the hill to create a tiered visual effect during the peak flowering season.
The elevated position provides a clear line of sight toward the peaks of the Tanzawa range, including Mount Oyama on clear days.
Atsugi Tsutsuji no Oka Park is a hilltop public park in the Morinosato residential area of Atsugi, renowned for its extensive collection of azaleas. The park features a sprawling hillside densely planted with approximately 48,000 azalea shrubs that bloom in vivid shades of pink, white, and red. Walking trails traverse the slope, connecting the residential outskirts to higher ground that offers expansive views of the Tanzawa Mountains. The park is designed with multiple elevated observation decks and wooden walkways to facilitate viewing the flowers without damaging the landscape. It serves as a local recreational space featuring open grassy areas and wooded sections. The facility is maintained by the city of Atsugi and provides basic public amenities for visitors.
The upper observation platform provides a panoramic view looking down over the hillside azaleas with the Tanzawa Mountains in the background.
Visit during the peak blooming season in late April or early May for the full visual display.
Wear sturdy walking shoes, as the park is situated on a hillside with multiple inclines and steps.
Bring a portable picnic mat, as there are open grassy spaces designated for relaxation.
Do not attempt to visit in the middle of summer if you are sensitive to heat, as the park has limited deep shade along the main flowering slopes.
Stay on marked paths and wooden walkways to protect the azalea plants; refrain from picking flowers or stepping into the shrub beds.
