Sayaka Ōnuki

Sayaka Ōnuki is one of those people who refuses to fit a single mold. A Kanagawa native with an arts degree from Tokyo Polytechnic, she has worked in gravure and on stage and even held an office job for a stretch in 2021, putting herself out there on her own terms. There's something genuinely refreshing about that. She's not playing the celebrity game loudly; she's just existing at her own pace, and I respect that more than I probably should.
