damn Kokuhaku is awesome & you're right , it's a very different if not extremely unique style Ken displayed in , something that was not present in his previous singles
and yup very strong influences of WILL in Kokuhaku which's really great & it also helps that Kokuhaku is produced by Seiji Kameda who's a member of Tokyo Jihen
That and also , Kokuhaku is selected to be used as the theme song for TV Asashi's drama W no Higeki which stars actress Takei Emi which is based on a mystery novel by Natsuki Shizuko that was adapted into a film back in 1984
anyway awesome comeback Ken

& he will be performing Kokuhaku next week on MUSIC STATION *__*
