The Imperial Palace Outer Garden is a vast green space located on the former site of Edo Castle, now open to the public as a national park. Spanning approximately 1.7km east-west and 2.2km north-south, it serves as an iconic landmark in the center of Tokyo. The landscape is defined by traditional Japanese aesthetics, including historic stone walls, moats, black pine trees, and lush lawns. Today, it is a beloved destination for both locals and tourists for strolling and relaxation.
This area once formed the western part of Edo Castle during the Edo period. Following the Meiji Restoration, the site underwent significant development to become the landmark seen today. During the Meiji era, extensive tree planting was conducted, and by the Taisho era, the quintessential Japanese landscape of black pines and lawns was established. The site continues to serve as a vital location for national ceremonies. Notable structures, such as the Sakurada Gate, are designated as Important Cultural Properties of Japan, preserving the architectural heritage of the era.

The Imperial Palace Outer Garden is filled with elements that evoke a sense of history. The Nijubashi Bridge area is one of the most famous photographic spots. Other highlights include the Sakurada Gate, which retains the form of a 'Masugata' (square-shaped) gate characteristic of Edo-style fortifications, as well as the historic stone walls and moats. The Wadakura area features a beautiful fountain system integrated into the landscape, while the Kusunoki area houses a statue of Kusunoki Masashige, adding a layer of historical depth to your visit.
The garden is always open, making it an ideal spot for a daytime stroll. At Wadakura Fountain Park, you can enjoy the water displays during the operating hours (10:00–21:00), with occasional light-up displays after sunset. Please note that access may be restricted during national ceremonies or high-security events, so it is recommended to check local news or official announcements in advance.

Visitors can enjoy walking or resting within the expansive grounds. The Wadakura area provides information corners and facilities for relaxation. While walking is the primary activity, there are specific rules for movement; for example, running on pedestrian paths is prohibited, and runners should use designated areas (such as the light green paved sections). The area also occasionally serves as a hub for events like the Palace Cycling program on Sundays.
The area surrounding the Imperial Palace is home to many significant cultural and historical institutions. To the north lies the Kitamaru district, featuring the Nippon Budokan, the Science Museum, and the National Archives of Japan. To the south, the area transitions into the vibrant Hibiya district. Many visitors pass through the Imperial Palace gardens when traveling between these major landmarks.
