premise: "King of the Jungle" is a song written and recorded by English girl group Bananarama. It was released as a single in Japan only from their self-titled second album in 1984. The song is the second single from Bananarama to be a Japanese-only release (following "He's Got Tact" in 1982).
hypothesis: King of the Jungle was released in Korea.
reason: They said it was their second japanese only release. So based on the information iit would be that it was never released in Korea if it was only released in Japan.
