Studio Ghiblihas been making headlines recently—largely due to the viral spread ofAI-generated artwork mimicking its iconic style. But it’s important to remember that Studio Ghibli is more than just a recognizable aesthetic; it’s a vibrant creative community, anchored by legendary Academy Award-winning directorHayao Miyazaki. Over the years, the studio has nurtured numerous emerging talents in the anime world, including Hiromasa Yonebayashi (When Marnie Was There,Mary and the Witch’s Flower) and animator Katsuya Kondo, whose character designs helped define the look ofKiki’s Delivery ServiceandOcean Waves.
Now, another Ghibli alumna is stepping into the spotlight. Hitomi Tateno, who spent 27 years at Studio Ghibli as an animator and animation supervisor on films such asPrincess Mononoke,Grave of the Fireflies,Spirited Away, andKiki’s Delivery Service, has taken on the role of producer forCocoon: From Girls in Summer. This 60-minute special, based on the manga by Machiko Kyo, aired on March 30th on NHK-TV in Japan.
