Chijimatsu was born on November 30, 1937. She graduated from
Kyoritsu Women's Junior and Senior High School. Ever since she was a young girl, she had a deep love for acting, and joining a children's theater group only got her to become more deeply hooked into it. She wanted to become a news announcer, but gave up on the idea after being told it was impossible because of her distinctive voice. In 1960, during her time as a student at the
Tokyo Announcing Academy, Chijimatsu started doing
radio work and other activity fields after she had made an appearance in a television commercial. She started her career as a
voice actress after she was introduced by a
Toei Animation producer. Her anime television series debut was Turnip in
Sally the Witch. While voicing Turnip, she wound up causing trouble for the staff, as she struggled to lip-sync with the animation on-screen and thought about quitting. Chijimatsu was formerly a founding member of Tokyo Artist Pro and
Aoni Production, but played a huge role in establishing
Production Baobab with
Kei Tomiyama,
Kōsei Tomita, and
Kenichi Ogata. After working with
Production Baobab and
Arts Vision, she joined her current affiliation
81 Produce on October 21, 2013. She voiced
Tamako Nobi in the
Doraemon anime series and the
Doraemon movie series for 26 years. She stepped down in March 2005 when the anime was
rebooted with a new voice cast, with the role of Tamako being taken over by
Kotono Mitsuishi. Before she stepped down from the role, she made a guest appearance on the
Waratte Iitomo! segment "A World You Think You Know, But Don't Really" with
Noriko Ohara,
Kazuya Tatekabe,
Miina Tominaga,
Mari Shimizu, and
Akira Kamiya. When voicing Pyonkichi on
The Gutsy Frog, she had previously voiced gentle and lovely female characters in
foreign film dubs, so when she initially started, she ended up breaking down in tears, saying, "I can't say such rough lines." Her family consists of her husband and their two children. Her first child, a son, was born while she was on
Tiger Mask. During her pregnancy, her co-stars would often tease her, asking, “Is the baby in your belly talking?” After the birth of her son, her voice ended up changing and she struggled getting it back to how it sounded before. Her second child, a daughter, was born in 1979.
Doraemon began broadcasting shortly after the birth of her daughter, so Chijimatsu developed a very strong, deep, and personal attachment to portraying mother characters. In 1978, she joined the Cosmos Tanka Society and in 1994, joined the Sanbashi Association. She published a poem collection titled
Space Mist in 2002. In 2016, Chijimatsu received the Lifetime Achievement Award at the 10th
Seiyu Awards. ==Personality/Characteristics==
