Short bio
Seita is a Japanese performer and model-turned-idol of NEXZ known for his warm smile, sun-kissed visuals, and fashion sense.
Background
Seita was born in Saitama, Japan, and grew up with an older brother in a family environment that encouraged creativity and independence. Before entering the idol world, he spent around seven years working as a model, building camera confidence and an eye for styling long before he ever stood on a survival-show stage.
His turning point came after discovering the music of Stray Kids, whom he has credited with inspiring his dream of becoming an idol. Motivated by that spark, Seita auditioned in Seoul, South Korea, eventually joining JYP Entertainment as a trainee for approximately seven months.
In 2023, he appeared on Nizi Project Season 2. The transition to living and training in South Korea was challenging at first. He was unfamiliar with the language, culture, and distance from home tested his resilience. But those early struggles became part of his growth story. In the program’s final results, Seita placed 7th overall and was the last member revealed, creating a memorable debut moment for viewers. He officially debuted with NEXZ on May 20, 2024, bringing with him a blend of model poise and understated charm.
