Ryukyu glass

Ryukyu glass is a glass craft made mainly in Okinawa main island.
Its history is said to be the beginning of the mid Meiji period.
However, Ryukyu glass has been recognized as a traditional craft in Okinawa Prefecture in 1998.

In recent years there are many workshops that open experience classes such as Ryukyu glass.

Manufacturing method of Ryukyu glass

There are two ways to manufacture Ryukyu glass.

  • Drift
  • Type blowing
Depending on the shape of the making, you decide which method to use.


The glass that has been heated until it becomes hot at high temperature is taken up by using a cylinder called "fukikan".
After that, it blows the breath and inflates glass.
It is not this method of blowing blowing in the image generally as a manufacturing method of the glass crafts.

It is necessary to shape the glass before it is cooled.
It is an interesting way of producing the feeling and taste of each craftsman.

The type blow method is put into a mold made of gypsum and metal after the glass is wound with a blowgun.
And it is possible to make a glass in the form by blowing and breathing.

This type blowing method is used if you want to produce large quantities of the same shape.
Because of the difference in the finish by the material and craftsmen that use the same type, it is possible to taste different one by one.

History of Ryukyu glass

Manufacturing process of Ryukyu glass

It was around 1998 that Ryukyu glass was recognized as a traditional craft of Okinawa.
However, it is said that the history began in the middle of the Meiji period more than 100 years ago.

At that time, it was manufactured by a glass craftsman from Osaka and Nagasaki.
It is said that it was made in the vicinity of present nishitakeyama Park and Naha city of Naha city.

Around this time, a jar was made for putting the lamp, the lamp, and the pickles.
However, by the Second World War, the glass workshop is devastating.

Ryukyu glass developed after World War II

After World War 1947, glass production was resumed at Naha City yogi.
The popularity as a daily necessities and souvenir increases mainly by U. s.personnel such as garrison.

However, due to the air raid during the war, it fell into a situation where the material was insufficient.
Then, the craftsmen watched the empty bottle of alcohol and juice that was discarded at the U. s.military facilities.
This bottle was broken and melted, making the recycled glass raw material.

At that time, it was the main visitor of the military official still, and the design also seems to have many Americans favorite.
After the war, it will be produced mainly on wine glass and vase.
