The garden layout uses white pebbles and sand to outline the exact placement of former administrative offices and living quarters.
The site includes a 'Great Well' that is deep enough to have provided a secondary water source for the castle compound during sieges.
It was officially recognized as one of Japan's 'Best Couples' Holy Lands' due to its romantic atmosphere and evening illumination.
The garden contains an extensive collection of citrus cultivars reflecting the region's historical and modern status as a center for orange production.

Matsuyama Castle Ninomaru Historical Site Garden occupies the former residence of the castle's feudal lord within the Ninomaru compound at the base of Mount Katsuyama. The site is designated as a National Historic Site and features the reconstructed layout of the original administrative buildings marked by white stone outlines on the ground. A prominent feature is the open-air garden which utilizes a flowing water canal system inspired by ancient palace floor plans. The grounds contain a variety of citrus trees representing Ehime Prefecture's agricultural heritage. Large stone walls from the Edo period surround the perimeter, providing physical evidence of the castle's defensive architecture. The park is integrated with the wider Matsuyama Castle complex but offers a distinct ground-level perspective compared to the main donjon atop the hill.

Do not attempt to hike from the Ninomaru site to the main castle peak during high summer heat without water, as the incline is steep.
Closed on Mondays, or the following day if Monday is a public holiday; also closed during the year-end holiday period.
