Tosaiga "Ryu no Tama - Nyoihoju - Koei" (30 angle)
The "Ryu no Tama - Nyoihoju" is a series created as an attempt to research the technique of burning phosphorescent materials into Tosaiga ceramic paintings. The phosphorescent material absorbs light, stores it, releases energy in the dark, and shines. Things you couldn't see in bright light can be seen by darkening it. The "Nyoihoju" series was created using these materials, made in a bright room with bright colors. But turn the lights off in the room and a "Nyoihoju (Ryu no Tama)" (Dragon ball) suddenly appears.
