"Kanasa" means beloved. In the Okinawan language, kanasan is the word for something dear, something cherished—and the fireworks that bear this name rise over a beach in Ginowan, in the early, subtropical summer of Japan's southernmost islands. Okinawa's rainy season ends far sooner than the mainland's, so that by July the islands are already deep in high summer. The fireworks open above an emerald sea, the light scattering across waters so clear and bright they seem to belong to a different country. This is a Japan most visitors never imagine—palm trees, coral reefs, a sky that holds the heat long after dark. And the night is full of sound. The three-stringed sanshin, Okinawan pop songs, the drums of the eisa dance—the whole sonic texture of island summer wrapped around the fireworks. There is a softness to Okinawan celebration, an ease the mainland lacks. A festival named for what is beloved, lit above a warm sea, carrying in its very name the particular gentleness of the people who made it.
