Hiroy Glass Studio

Ita area where our studio is located is a small village which was developed in 1671.

History of Our Studio Area

Ita area where our studio is located is a small village about three kilometers around, which was developed after reclamation of the sea in 1671. Rice fields were cultivated to support the management of Shizutani School (a designated national treasure), a school for common people in the seventeenth century. With the introduction of Chinese fields system, the cultivated land was divided into nine. Eight outer sections were assigned to eight families and the one in the center was communally cultivated and the harvest from the common field was used to support children’s education at Shizutani School. My father is a rice farmer here, too.
Also, Bizen, my hometown area, is famous for Bizen ware with a history of about 1000 years. Since the old days, Bizen ware has been made with clay dug up from the bottom of rice fields and rice husks and straws have been used for firing.

Production Policy

In running a studio, we aim to provide an idea of lifestyle in which people choose and use vessels, at various scenes of home life, in a way they choose their clothes. Daily dining tables do not consist of glassware alone. We wish glass tableware would be chosen and used with joy along with various tableware and cutlery of ceramics, porcelain, lacquer ware, metalwork and woodwork. We would like to make proposals that only We can make, such as making suggestion and help for our customers’ tableware selection.


In the year I built my studio in this area, it was a poor rice crop year due to the bad weather and there were lots of immature rice grains. Then I wondered if I could make use of those rice grains. I thought about drawing colors in glass by grinding and dissolving them into glass. It did not work out at first but through trial and error I managed to produce a grey color in the transparent upper layer and a beautiful blue color in the bottom.

"ren" Line

This line was inspired by the latticework found on doors and windows of traditional Japanese houses. It features a stripe pattern and colorful shade.

< Production Process of "ren" Line >
  • First, I make a colored glass ball by gathering molten glass onto the end of a long metal pipe and then sprinkle powdered color glass on it.
  • After cooling down the glass ball overnight, I scrape off the colored outer layer and make a stripe pattern.
  • The glass ball is put back to furnace and put on to the metal pipe again. Then I mold it into various shapes using glass blowing technique.
