Alan is the genial Japanese-American owner of Hooper's Store on Sesame Street. Alan took over the reins from Mr. Handford in Episode 3786, and soon became particularly close friends with Baby Bear and Telly Monster. Alan later hired Gabi and Miles as his assistants. Alan's newest assistant is Chris Robinson (the nephew of Gordon and Susan).
In Alan's first appearance on the show, Big Bird holds a Birdketeer meeting in the arbor, and the new owner of Hooper's finds himself as an overworked caterer for the meeting. As the day goes on, Alan is tempted to ask them to take their meeting somewhere else, but the Birdketeers then give Alan a big welcome to the Street. They praise him for his help in providing snacks and other things to eat for the meeting, thus marking the beginning of yet another beautiful relationship with the residents of Sesame Street.
- At a panel at Eternal Con in 2019, Alan Muraoka joked that since Alan's place of residence has never been seen or referenced on the show, he imagines Alan resides in the basement of Hooper's Store with a mere cot and kerosene lamp.
