This work is inspired by the unstable weather in Toyama, Japan. “Holding Sunshine” is a vehicle to visualize natural light, and the brightness of the work depends on weather. This work captures and make us appreciates subtle sunshine even in cloudy day. The work uses a phosphorescent glass that absorbs UV light like sunshine then emits it slowly over time to illuminate darkness without any light resources. I was drawn to using this type of glass to record and contain sunshine because the sun does not shine much in Toyama. The cloudy environment helped me realize how vital sunshine is for me both mentally and physically. How can I bottle and release sunshine in glass? How can I visualize sunshine? Can I transfer sunshine from here to there?
