All of her subsequent albums, such as Mother Sky and The Last Waltz, also explored tragic or morbid themes.
Throughout her performing career, Morita was a secretive and reclusive performer who always wore round sunglasses and grew her curly hair long to hide her identity.
This led to a revival of interest in her work and the release of a greatest hits album.
In later years, Morita went on to marry Maeda Ado, her former manager.
Morita died of heart failure eight years later on April 24, 2018, at the age of 65.
