Sakura (さくら) is the name of a traditional Japanese folk song depicting spring, the season of sakura. Contrary to popular belief, the song did not originate from ancient times (as in, not from the Heian period or prior). It was first composed during the Edo period for children learning to play the koto. Originally, the lyrics "Blooming cherry blossoms" were attached to the melody. The song has been popular since the Meiji period, and the lyrics in their present form were attached then. It is often sung in international settings as a song representative of Japan. Throughout the ages there have been many rearrangements of the song, but Michio Miyagi's rendition is often regarded to be the best of them all.

Sakura Ogawa (小川さくら Ogawa Sakura) is a character in the novel Battle Royale, and the film and manga of the same name. The English adaptation of the manga romanizes her surname as Ogawai. In the film she was played by Tomomi Shimaki.
