Blue Zone (song)

"Blue Zone" is a song recorded by Japanese singer Shizuka Kudo for her fourteenth studio album, Full of Love. It was released through Pony Canyon as the album's lead single on April 7, 1999. The song featured on TV commercials for Toyo tires. A song titled "I.n.g" was originally slated to be released in place of "Blue Zone". Since it does not appear on Full of Love, it is unclear whether the song was scrapped or if "I.n.g" was simply an alternate title. "Blue Zone" is the third and last in a trilogy of singles with "Blue" in the title: "Blue Zone" is preceded by "Blue Velvet" and "Blue Rose", respectively.
