In the middle of one brother and one younger brother, Yukiko Murayama (Tokoko) is an opera singer under the stage name Tamaki Miura. She was a celebrity who also released records, but she stopped singing in the middle of her career due to the Vietnam War. Akiko's father is a police officer and opposes Akiko's entry into the entertainment world. Akiko's mother (who was a hairdresser) also opposed it at first, but when her daughter's acting debut was decided, she changed her mind and supported her entertainment activities and gave singing advice. She continued supporting Akiko until her death on March 10, 1995 at the age of 85. The piano used by her mother is preserved in Akiko's residence.
