Anna Tsuchiya to sing for Kamen Rider
It has been announced that Anna Tsuchiya will be collaborating with the Kamen Rider franchise to celebrate its 40th anniversary. "Kamen Rider Fourze", the latest show in the franchise, begins airing Sunday at 8:30 AM and will feature Tsuchiya singing the opening theme "Switch On!". The theme was revealed as a last minute announcement as the theme song artists are typically announced three to four weeks prior to the start date at the press conferences. Tsuchiya sites her children's love of Kamen Rider as a strong reason for participating with the series.
