Seiran Fukushima is a Japanese child actress and voice actor known primarily for a single, prominent role in an international streaming production. Fukushima came to public attention in December 2022 with the release of the Netflix hybrid live-action and CG series Gudetama: An Eggcellent Adventure. In this series, which is based on the popular Sanrio character Gudetama, Fukushima provided the voice for Shakipiyo, a newly hatched and determined chick who serves as the enthusiastic sidekick to the title character, a lethargic egg.

At the time of the series release, Fukushima was reported to be ten years old. Several news outlets and industry sources describe her as a promising child actress. Her performance in Gudetama: An Eggcellent Adventure marked her most high-profile credit, bringing her work to a global audience through the Netflix platform. The series itself received recognition when it was nominated for an International Emmy Award in the Kids Live-Action category in 2023, a notable achievement for the production and its cast.

Beyond her work on Gudetama: An Eggcellent Adventure, Fukushima has a limited number of known credits. A separate series, A Day-Off of Kasumi Arimura, is also listed as part of her acting work. In terms of industry collaborations, her most frequent professional partnership has been with voice actor Shunsuke Takeuchi, who voiced the protagonist Gudetama as well as over twenty other egg characters in the same series. Her role as Shakipiyo is an example of a young actor voicing a character of a similar age, a common practice in animation and voice-over work. No other major voice roles, recurring collaborations beyond this single project, or extensive career achievements have been documented in available sources.
