Ninomaru Garden

A showcase of traditional Japanese landscape design

Ninomaru Garden, located within the Imperial Palace East Gardens, is a fine example of traditional Japanese garden design. Originally part of Edo Castle, the garden has been maintained to reflect its design from the mid-18th century, a period known for significant cultural and landscaping developments in Japan. Opened to the public in 1968, the garden now includes a notable grove of 220 trees, donated from each of Japan’s 47 prefectures.

Ninomaru Garden holds historical value due to its original role as part of Edo Castle’s defense. The garden’s layout is inspired by mid-1700s designs, which was a time of cultural growth and emphasis on garden aesthetics in Japan. Although the original structures were lost to a fire in 1863, the area within the Imperial Palace East Gardens was opened to the public in 1968, allowing visitors to connect with the site’s historic past.

In the northwestern corner of the garden, there is a grove, which is thought to symbolize a connection among Japan’s regions. These some 220 trees were reportedly donated from every prefecture across the country as a demonstration of national unity. Regardless of their origins, the diversity of the trees contributes to the garden’s overall appeal.

Today, Ninomaru Garden is valued for its demonstration of Japanese garden design and commitment to preserving nature. While the original buildings are gone, the garden provides a glimpse into the landscaping principles of historical Japan. Located in the heart of the city, Ninomaru Garden offers a peaceful retreat that blends natural beauty with historical significance.
