44-year-old Masahiro Nakai, the leader of the now disbanded boyband SMAP, has been dating a 32-year-old choreographer and dancer Maika Takeda for the past 6 years.
Nakai's secret relationship was first published by Shukan Post, a tabloid magazine that has taken photos of the two together. Various other Japanese new agencies, including Nikkan Sports and Sanspo, have ran their own stories about the relationship.
According to reports, Nakai's girlfriend has been a backup dancer for artists such as Namie Amuro and Miliyah Kato. She has also helped choreograph AKB48's dances since 2010.
The two are said to have their own apartments in Tokyo, but live near each other. Although they have their own place, the two regularly cohabitate.
While a member of SMAP, Nakai was unable to date openly. The couple's love was fostered in secret over the years. With the group now disbanded, the two no longer have to keep the relationship hidden.
