Island (J-Pop label run by UNIVERSAL SIGMA; formerly “ユニバーサルミュージック株式会社 アイランド”. Do not use for American/European music!)
This label was launched as an imprint of UNIVERSAL J in 2002. It was shortly after spun off into its own company/division of Universal Music Japan. It again became just an imprint in 2004, managed by the newly created UNIVERSAL SIGMA.
