ADERIA (Ishizuka Glass)
Japanese glass tableware from Iwakura, Aichi — ADERIA RETRO, Tsugaru Bidetro, and 200 years of glassmaking.
Ishizuka Glass Co., Ltd. is a Japanese glass manufacturer founded in 1819 in Iwakura City, Aichi Prefecture — one of Japan's oldest glassmaking companies, with over 200 years of continuous production. Under the ADERIA brand, Ishizuka produces glass tableware that ranges from the widely recognized ADERIA RETRO series — vintage-style footed glasses with retro patterns that became popular in Japan's coffee shop culture of the 1960s–80s and have been revived for contemporary use — to the premium Tsugaru Bidetro line, which applies Tsugaru Vidro (Aomori glassblowing) techniques to sake cups and tableware in distinctive vivid colors characteristic of that Northern Japan craft tradition.
PROFILE Company & Brand Story
Ishizuka Glass was founded in 1819 in Iwakura City, Aichi Prefecture — making it one of Japan's oldest glass manufacturers, predating the Meiji-period industrialization that brought Western glassmaking techniques to Japan in force. The company developed across two centuries of Japanese glass production history, expanding from traditional glassblowing into industrial glass packaging and contemporary tableware.
The ADERIA brand name became most widely recognized through the footed glasses produced for Japan's café and coffee shop culture of the 1960s through 1980s — a period when Western-style coffee shops (kissaten) were a central feature of Japanese urban social life. ADERIA's melon soda and ice coffee glasses, with their characteristic retro patterns, became iconic objects of this era. The ADERIA RETRO line revives these designs for contemporary use: the same forms and patterns that defined kissaten culture, now produced again for customers who remember them and those who encounter them for the first time.
Tsugaru Bidetro represents a different dimension of Ishizuka's glass production. Tsugaru Vidro is a glassblowing tradition from Aomori Prefecture in northern Japan, characterized by its use of vivid, layered colors — transparent blues, greens, and ambers that shift in intensity and hue depending on the angle of light. The technique originated as a practical coastal craft using recycled glass from fishing floats, and its characteristic colors reflect this material heritage. Ishizuka's Tsugaru Bidetro line applies these techniques to sake cups, small vessels, and decorative glass objects.
The TEBINERI series takes a different approach: handmade glass objects with the visible marks of hand production — slight variations in thickness, surface texture from the making process, and individual character that machine production eliminates. TEBINERI means "hand-pinching" in Japanese — a reference to the handcrafting technique used in the production of each piece.
MC Container is a more functional product from Ishizuka: a glass storage container with a tight-sealing lid for food storage, produced to the material quality standards of a 200-year glass manufacturer but sized and designed for practical kitchen use.
ADERIA RETRO — Japan's kissaten glass culture revived

Objects that carry the visual memory of Japan's café culture, available in new production.
Tsugaru Bidetro — Aomori glassblowing tradition in vivid color
Tsugaru Vidro is a Northern Japan glassblowing tradition characterized by layered vivid colors: blues, greens, ambers that shift with light angle. The technique originated in Aomori from recycled fishing float glass. Ishizuka's Tsugaru Bidetro line applies these techniques to sake cups and small vessels — colored glass with a distinctively Japanese regional character.
