Shinjuku Gyoen National Garden is a serene oasis in the heart of Tokyo, offering a blend of traditional Japanese and Western landscaping. Originally the estate of the Naitō family during the Edo period, it was converted into a public park after World War II. Today, it's a beloved spot for both locals and tourists, famous for its sprawling lawns, tranquil ponds, and particularly stunning during cherry blossom season when the sakura trees are in full bloom.
