The idea starts from the desire of Dr. Yamanishi Hiromichi to reproduce on glass the story of The Tale of the Bamboo Cutter (竹取物語, Taketori Monogatari) which is a 10th-century Japanese monogatari (fictional prose narrative) containing Japanese folklore.
It is considered the oldest exitant Japanese prose narrative although the oldest manuscript dates to 1592.
The tale is also known as The Tale of Princess Kaguya (かぐや姫の物語, Kaguya-hime no Monogatari), after its protagonist.
It primarily details the life of a mysterious girl called Kaguya, who was discovered as a baby inside a stalk of a glowing bamboo plant.
Long before putting his hands on the glass or on the enamels, the Master has to study the shape and the proportions of the work.
To enter into symbiosis with the nature of the work, he designs by a pencil the entire scenario he has to reproduce.
After that, a meticulous examination of the forms and the colors must be done.
Every shade of color that he will use is prepared with a skillful mixing of the powders that will create the unique enamels used only for that panel.
Only after that he will be prepared enough to start the real creation of the work of art.
