Along with the Tokyo Minato Matsuri (Port Festival), the Kaiko-sai is one of two major seaside port festivals in Japan. Celebrations are mainly held at the Yokohama main pier, but often spill over into Yokohama Park. Building on the theme of Japan's contradictions, this park is split in two, with one side representing traditional Japanese styles and the other representing modern Western style. The festival has all the usual events you expect from a Japanese festival, such as dances and traditional music. What makes this festival special, however, is its seaside quality: Ships sail, fireworks are launched from barges, and exhilarating dragon boat competitions are held.
The festival also features a bazaar, where visitors can buy a keepsake of the celebrations.
