Hiroshi Tamaki and Hitomi Shimatani have broken up, it was learned on Saturday. They reportedly started dating around last September, but it looks like their busy careers caused them to split after only half a year.

Since the start of this year, Tamaki was occupied with filming for the drama series "Shikaotoko Aoniyoshi" and with recording a new album and single. Meanwhile, Shimatani also released her own new single and starred in a musical. According to one source, the couple was rarely able to meet due to their schedules, and they finally decided to break up at the end of March.
