Chidorigafuchi is actually one of the moats that was originally built to defend Edo Castle, which is now the Imperial Palace. Later on, it was also used as a water source. These days, it’s famous as one of Tokyo’s top spots for cherry blossom viewing. The name “Chidorigafuchi” comes from the shape of the moat, which is said to look like a plover—a bird called “chidori” in Japanese. Plus, a lot of these birds used to come here in the winter. The cherry blossoms, mostly of the Somei Yoshino variety, usually reach full bloom from late March to early April, but it can vary a bit depending on the year. It’s a good idea to check an official tourism website for the latest blooming updates. When you visit, you can stroll along the walking paths, or even rent a boat and enjoy the cherry blossoms from the water. During the Sakura Festival in Chiyoda Ward, the 700-meter path along the moat is beautifully lit up with LED lights, making it perfect for viewing cherry blossoms at night. The closest station is Kudanshita Station, served by the Tokyo Metro Tozai and Hanzomon lines, as well as the Toei Shinjuku Line. It’s about a 5-minute walk from Exit 2. To avoid the crowds, going early in the morning or on a weekday is your best bet. Make sure to wear comfortable shoes, bring your camera, and please take your trash with you to help protect the environment.
