He is small, fluffy, and utterly charming: Hamtarou is one perfect little hamster! After relocating to a new home with his owner, fifth-grader Hiroko Haruna, Hamtarou encounters other hamsters and swiftly befriends them. The band of hamster explorers refers to themselves as the Ham-Hams, and there is nowhere they will not venture. The Ham-Hams embark on wild adventures throughout the city while their owners are absent, visiting everything from theatrical performances to magical realms of candy. Meanwhile, the humans deal with their own dramas... Hamtarou encounters a vast cast of distinct personalities, finds himself in—and out of—some rather precarious situations, and even assists Hiroko and her friends more than once. Through it all, he never ceases to be irresistibly cute. It is Hamtarou time!
