Introduction of Shimajiro and Friends
- Shimajiro

- Mimi-Lynne
- Mimi-Lynne is a mild-mannered girl who would rather be playing the piano or painting a picture than getting caught up in Shimajiro's adventures. Still, she can be surprisingly brave at times.
- Flappie
- With his over-the-top personality, Flappie can make even the toughest frown turn upside down. He and Shimajiro are best friends and can always be found together.
- Nikki
- Nikki is the big sister everyone wishes they had. She's great at sports, is caring, and always stands up to bullies. Naturally, she's always up for adventure with Shimajiro and the gang.
- Dr. Roarson
- This eccentric inventor and explorer is always trying to surprise Shimajiro and his friends with his fancy inventions, which tend to break down at really inopportune times.
- Hannah
- Shimajiro's 3-year-old sister is as curious as her brother, although her curiosity can sometimes get her unwittingly into trouble. Shimajiro is her favorite person in the world!
- Shimajiro's Dad
- Shimajiro's Dad is a postman. He loves his job, but he also makes sure to spend quality time with Shimajiro and Hannah before and after work.
- Shimajiro's Mom
- Although generally cheerful and kind, even Shimajiro's Mom finds her patience tested at times by Shimajiro's recklessness.
