    Daisho Glass

    Daisho Glass Co., Ltd. provides premium packaging design and extraordinary quality for food, beverage, pharmaceutical, beauty & cosmetic industry.

    Daisho Glass Group has two production bases in Kushiro factory (Hokkaido pref.) and Naruto factory (Tokushima pref.).

    Kushiro factory makes a variety of plastic parts for medical products as plastic caps for infusion bags under our clean and fully-automated facilities.

    Naruto factory makes plastic bottles and glass bottles including 'GYOKU' which only we can make in Japan.

    We build up a close network with a number of affiliated factories and it enables prompt and reliable response from production of bottles to secondary processing. We give careful consideration to the environment by stopping the use of mold release agent or using an electrical fumace to reduce the emission of CO2 to nearly zero. A variety of process for both glass and plastic products enables us to meet different needs of our customers.


    Nobody knows when or where contingency appears. That's why we seriously conduct a full inspection one by one.

    Our products are always safe for use and never betray trust of our customers. This is more important performance than anything else for the products of Daisho glass Co., Ltd. So, we conduct a full inspection which our competitors rarely conduct. We spare no effort to gain safety and trust.


    Quality control mainly conducts dimension measurement or performance check as drop test and leak test. In quality control, we store the approved master samples from our customers to maintain stable quality. We conduct a total quality control from your order to shipment including a preparation of delivery specification. We are always trying to enhance trust for our products from all angles.
