YKAA, founded by Atsuki Yamazaki and Maryana Kovalchuk in 2022, is an art and architectural atelier based in Sapporo, Japan and available worldwide. With experience in both Japanese and international environments, we strive to create a unique value in architecture beyond existing ideas and conventions. We strive to bring a humanistic approach to our practice with a deep understanding of people’s needs and an appreciation for local craftsmanship.
