Born in 1988 in Kurume, Fukuoka Prefecture. After six years of training at a Ryukyu glassblowing studio in Okinawa, he moved to Toyama Glass Studio. In 2022 he established KOGA GLASS STUDIO and went independent, and in 2024 he opened his own studio in Fukuoka. Using the blown glass technique, he harnesses the fluidity of molten glass to express a distinctive sense of "ripple and sway," creating everyday glass pieces such as drinking glasses and katakuchi (lipped pouring bowls).
