Yumi and Keita, the creative duo behind STUDIO DOUGHNUTS, design everything from spaces to furniture and products. Their connection with Satomi runs deep, from selecting their engagement rings to designing SKJ’s Tokyo store. Their philosophy of creating spaces that complement the individual without being overly assertive is a value they share with SKJ. They love how Satomi’s jewelry isn’t just about the perfect design when you wear it — it’s about layering pieces to tell your own story and shape your unique perspective.
How did you meet Satomi and become friends?
Satomi and I met in 2012 during a trunk show at FHAMS in Kyoto, where I bought a donut-shaped earring. After that, we helped set up her NYC showroom and worked together to establish STUDIO DOUGHNUTS in Tokyo. In 2013, I visited her studio in Union Square, NY, where Keita and I chose our engagement and wedding rings, which we still wear. Over the years, we’ve stayed connected through various events and pop-ups, including SKJ’s first Tokyo pop-up in 2017, where she introduced us to her team.
What was your first impression of Satomi?
Yumi: I found Satomi to be a quiet, kind person with a gentle smile.
Keita: She’s a perfectionist. When we stayed with her in Astoria, she made us rice balls for our early morning flight—she’s attentive and thoughtful.
How would you describe SKJ’s brand?
What makes SKJ stand out for you?
Yumi: SKJ jewelry fits seamlessly into my life. I was never a big fan of jewelry before—I often found it bothersome or quickly lost interest. But SKJ pieces feel different; they're comfortable, like a part of my body. They’re the kind of jewelry that invites layering and makes me want to keep adding to my collection. I don’t have much to compare them to, but I know other earrings can feel heavy or irritating, while SKJ pieces blend seamlessly into my life.
Satomi is confident and incredibly skilled. Many women quickly jump into jewelry design, but I can tell Satomi has accumulated a lot of knowledge, skill, and material expertise, and she has confidence in her craftsmanship. She’s a person with a solid core who has worked hard and continues to create, no matter the form.
What are some of your favorite SKJ pieces?
I own seven rings, a necklace, and four sets of earrings. My engagement and wedding rings, which have a crown-like design, are particularly special. For our 10th anniversary, we plan to buy a new ring. Satomi’s pieces are always one-of-a-kind and beautiful. Originally, I wanted an opal, but when I talked to Satomi, I joked with her that my husband would buy it for me, and Satomi said, “It should be a diamond!”
What personal values resonate with SKJ’s philosophy?
Keita and I value balance and space in our designs, similar to Satomi’s approach to jewelry. Her pieces allow for layering and reflect the wearer’s personality, creating a harmony that feels deeply personal.
How would you describe your relationship with SKJ in one word?
Yumi: Love.
Keita: Admiration. Satomi is incredibly dedicated and constantly challenging herself, and I look up to her.
