| Juice=Juice Gets Fresh Spark: 14-Year-Old Glasses Icon Niina Hayashi Joins the Lineup (Hello! Pro) |
At just 14 years old, Niina's already got a bit of an online legacy. Fans of Hello! Project may recognise her as “the trainee with the glasses” — a nickname that blew up when she first joined Hello Pro Kenshuusei in March 2023. With her calm vibe and signature specs, she quickly became a fan-favourite even before making her official debut.
Now that she’s Juice=Juice’s newest member, fans have been wondering: Will she keep the glasses on stage? Well, nope — it’s been confirmed she’ll be performing without her glasses, although she’s sticking to them in daily life. (Fashion icon behaviour, honestly.)
Her full activities with Juice=Juice are set to kick off in September 2025, but she’s already made her first appearance as part of the team. Her member colour is bright green — fitting, really, considering her fresh start and youthful energy.

🎤 What Fans Are Saying
Since the announcement, fan communities have been buzzing — some thrilled by her energy, others nostalgic about her Kenshuusei days. A popular comment on Japanese fan forums summed it up nicely:
“She was already an idol in our eyes when she was a trainee. Can’t wait to see her shine!”
Meanwhile, international fans on Instagram and TikTok are loving the contrast between her soft-spoken trainee days and her new, bold stage look.
With a full debut in September, we can probably expect Niina to join in on upcoming singles, tours, and Hello! Project events later this year. And with her growth over the past two years as a trainee, Juice=Juice might just have snagged one of the most promising rookies in the game.
Bright green penlights at the ready — Yasshii era is coming.
