LOVE9CUBE was launched back in 2005. It is a mobile only fanclub, and cannot be used outside Japan as you need a local phone company subscription.
LOVE9CUBE PREMIUM was launched back in 2010.
Following her regular fanclub, her team launched this additional fanclub for the fans who wanted even more exclusive contents. This allow them to access to live tickets even before the regular LOVE9CUBE members as well as other contents.
LOVE9CUBERS will be launched next year, May 2020.
This will be the unique fanclub as the two first will disappear.
