A new platform for video, novels, and screenplays

StellaJean

Launched in April 2026, StellaJean is the first new Japanese* platform designed to convey the emotional depth found in stories through video, novels, and screenplays. This platform streams thrilling video works primarily consisting of short drama productions and short films. Since it also features functions for submitting novels and screenplays, StellaJean creates pathways for making adaptations as a platform that brings video creators and the creators of original content together.

We aspire to make StellaJean into a space where all artists, both professionals and amateurs, can freely express themselves and encounter a great number of radiant emotions along the way.

Brand Message:
"Just a Story
- A Thousand and One Seconds of Sparkling Emotions."
