Bubun is a jewelry making duo of Megumi Jin and Nobuyuki Jin, based in Japan. Fascinated by glass as a student, Megumi studied glass coldwork and kilnwork at Tama Art University, where she created objects and jewelry.

While continuing to make jewelry privately after graduation, she met Nobuyuki, who has a background in design, and the two began working together, sharing a mutual sense of beauty. They started exhibiting their work under the name Bubun in 2016.

Bubun means "part" in Japanese. They believe jewelry becomes part of a person, both in the physical sense and in the spiritual sense. In 2019, they moved from Kanagawa to Kofu, the center of the jewelry industry in Japan, where they continue to work.
