I've always been used glasses to capture light.
But a new work "KAMISABIRU - a rusty Katana -", I tried to use Katana for the first time.
It took 2 years to complete because it was difficult to depict.
It was made possible by Japanese traditional paper 'Gampi'.

"Kamisabiru" is a Japanese archaic word .
Below is an explanation about "Kamisabiru":
some things live for a very long time or are used for a very long time, becoming celestial and possessing a deity within itself.
