Jun Sena (瀬奈じゅん Sena Jun), real name Asako Doi (土井麻子 Doi Asako) is a Japanese actress and former top star of the Takarazuka Revue's Moon Troupe, a Japanese theatre organization in which women portray all parts. She was born April 1, 1974 and grew up in Suginami, Tokyo. During her time in the Revue, she was an otokoyaku, an actress who specializes in male roles. After two years of intensive training at the Takarazuka Music School, she joined the revue in 1992 and reached top star status in 2005. Her nicknames are Asa and Asako. The first otokoyaku from her class of 1992 to reach top star status, she resigned her position as top star and retired in December 2009 after the run of Last Play / Heat on Beat and is now pursuing an acting career outside of the Revue.
Sena entered the Takarazuka Music School in 1990 and graduated in 1992. Upon graduation, she was placed in the Revue's Flower Troupe. During her time in Flower Troupe, she had one shinjinkouen (performance for junior troupe members) lead, and also had the lead role in two performances at Takarazuka Bow Hall. In 2002, she had her first lead role as a female character when she performed as Scarlett O'Hara opposite Yu Todoroki's Rhett Butler in an adaptation of Gone with the Wind.
As part of the Revue's 90th anniversary celebration in 2004, Sena made a special appearance in a Moon Troupe performance. She was also selected to portray the title role in the 2005 Moon Troupe production of Elisabeth. Although Sena was never officially transferred into Moon Troupe for these two performances and appeared only as a special guest, she was named the next top star of the troupe in 2005. From that point on until her retirement from the Revue in 2009, Sena would remain a member of Moon Troupe.
As a three-year-old, Sena was in a car accident during which she tore her Achilles tendon. Her doctor suggested certain exercises were necessary for her recovery, so her mother enrolled her in ballet lessons.
Her stage name, Jun Sena, is a combination of ideas from her parents: Sena comes from Ayrton Senna, her father's favourite Formula One racing driver. "Jun" comes from Jun Ariake, a former vice troupe leader of Takarazuka's Moon Troupe, with whom her mother went to high school.
