The name of this moat north-west of the Imperial Palace is said to come from its unusual shape. The structure of the walls resemble plovers, called chidori in Japanese.
It can be accessible by train.
Chidori-ga-fuchi Pedestrian Path is the most scenic spot around the moat, with a 700 meter-long tunnel of cherry trees in the spring.
The pathway is a 5-minute walk from Kudanshita Station or Hanzomon Station.
From late March to early April the walkways around the moat are tinted pink by hundreds of sakura trees. The Chiyoda Sakura Festival is held at the same time, so for the duration of the cherry blossom season the trees are lit up at night. This magical sight draws Tokyoites and visitors alike. Enjoy an evening walk under the glowing tunnel of flowers.
Later in the season the surface of the moat is almost completely covered in petals, creating the illusion of an ethereal pink river.
Nearby sights include Yasukuni Shrine, which is also a good spot to see cherry blossoms and autumn leaves, as well as the National Showa Memorial Museum, Nippon Budokan and Jimbocho, the book-seller's district.
