The garden features both Japanese (Edo, Higo, and Ise) and foreign iris varieties.
The site occupies an area of approximately 38,000 square meters.
The layout utilizes the natural valley terrain to facilitate water flow for the iris paddies.
The iris peak bloom typically occurs in early to mid-June.
Yokosuka Iris Garden is a specialized botanical park featuring approximately 140,000 irises representing over 400 different varieties. It is specifically designed to showcase the beauty of Japanese irises, with wooden pathways constructed over flooded fields. The garden landscape integrates hills, valleys, and small ponds to create a naturalistic wetland environment. Visitors walk on elevated boardwalks to view flowers blooming at eye level. The garden was established to preserve regional flora and historical horticultural practices in the Miura Peninsula. It remains a primary destination in Kanagawa for late-spring floral appreciation.

Wear comfortable, flat walking shoes as the boardwalks can be uneven.
Bring an umbrella or sun hat, as there is very little natural shade in the iris fields.
Check the official website's blooming calendar before your visit to ensure you arrive during the peak period.
Avoid visiting outside of the late-spring season, as the garden is significantly less active and lacks the signature floral display during the rest of the year.
Open seasonally from late spring to early summer; closed for the remainder of the year.
Do not step off the designated wooden boardwalks or touch the floral displays.
