Mrs. Hasagawa is a little old lady who owns a fruit stand. She is short and has glasses and gray hair.
In "Mrs. Hasagawa's Cats", it is revealed that she keeps many experiments, thinking that they are cats. It is unknown if she, being the caretaker of several alien life forms, is under the official protection of the United Galactic Federation as Lilo and Nani are.
Mrs. Hasagawa owns a large number of experiments whom she took in, thinking they were cats. Most of these experiments were activated when Mrs. Hasagawa mistook their pods for apricots and washed them to eat. They include:
- In the intro sequence of the series, Mrs. Hasagawa appears in two squares in the hula dance, with her image and movements mirrored to one another.
- Stitch mispronounces her name as "Hasagasawa".
- Aside from Hocker, the experiments under her care are not life-threatening, and most are only designed to frustrate their targets with mild inconveniences.
