The Good Design Award is a comprehensive evaluation program organized by the Japan Industrial Design Promotion Organization (JIDPO) to promote excellent design. The program is coordinated under the Good Design Products Selection System (commonly known as the G Mark System), established in 1957 by the then Ministry of International Trade and Industry (the current Ministry of Economy, Trade and Industry). Since then, the Good Design Awards have been given to outstanding designs for more than 50 years. The Award is one of the most prestigious design awards in Japan. Products labeled with "G Mark" are readily recognized by Japanese as well as many Asian consumers as products with supreme quality, functionality and sophisticated design.


SOURIRE® Tumbler

Friendly glass “SOURIRE”

  • The series of glass consists of four types of capacity and dimensions, responding to everyday needs, mainly, at home.

  • The concept is to give a feeling of safeness and the durability to those who enjoy glassware and also are hoping to use it for a longer period time.

  • The glass itself has been designed lighter in weight. Besides, the top portion has been strengthened, which is impact-resistant. Accordingly, you can have children and senior people handle the glass easily. We have also paid the attention of the changing mindset of the general public in Japan after the March 11, 2011 Earthquake that people should be gentle and soft to the others.

  • The shape reflects it, symbolizing an ordinary and happy dinning circle at home.
