In Iwakura City, Aichi Prefecture, where their head office is located, there is a row of cherry blossom trees on the Gojo River, which has been selected as one of the “100 Best Cherry Blossom Spots in Japan”. They have created glassware that is a copy of the petals that dance on the entire surface of the Gojo River, on the “Tebineri” that they have been making for the past 20 years.
Ishizuka Glass has its roots in glass manufacturing, which was started by Iwasaburo Ishizuka in Dota, Kani City, Gifu Prefecture, in 1819. At that time, he worked on beadro work as an order from the Owari feudal lord, and since then, he has been pursuing further glass manufacturing with the Meiji Taisho era. The turning point was in 1927.
With the success of melting white dough in the Siemens tank kiln for the first time in Japan, Ishizuka Glass will move on to mass production. The current Iwakura factory started operation in 1961, and the bottle business expanded with the full-scale entry into the tableware business, at which time “ADERIA” was born.
They have built an integrated production system that handles the entire process from design, molding, processing, packaging, and delivery in-house. Meetings can be held instantly between the persons in charge of each process, problems can be immediately identified, and efforts are being made to improve them. In addition, they aim to improve quality by establishing strict in-house quality standards and performing consistent quality control.
They also accept customer feedback by calling the Customer Relations Office, and it is very important not only to ask questions about products and purchases, to improve points and other requests, but also to point out what you have pointed out. They consider it to be information and important communication with the customers, and they try to answer each one carefully.
