This is an option combine a couple of iconic Tokyo runs into a longer run, and nearly all of it is pleasant and interesting. About 1 mile east of Yoyogi Park is Meiji Jingu Gaien Park. Considered the outer precinct of Meiji shrine, the park has some lovely tree-lined paths and is also the site of numerous facilities, including Jingu Stadium, home of a pro baseball team, a rink, a golf driving range, Seitoku Memorial Museum, and the site of the 2020 Olympic Stadium.

The park makes a nice connection or small add-on to the Imperial Palace loop. A 1.5 km loop around Meiji Jingu Gaien is ~1.5 km. Note: It is not permitted to run in the shrine at Yoyogi Park. 

Add-On: Our route combining Yoyogi Park, Meiji Garden, and Akasaka Palace passes by the Olympic Stadium used for the 2020 Tokyo Olympics. Adjacent to the stadium is a Sports Complex with a running trackccess: Kokuritsu-Kyogijo Station
