About
Sola Journal is a small publication by Sola Studio. Through UX field notes, engineering notes, and everyday observations, it explores how design, code, and daily life intersect.
The name comes from 陽子 (Yoko) — child of the sun — and 空 (sora/sola), the Japanese word for sky. It also echoes sol, the Spanish root for sun. A space for light and open thinking.
