一ノ蔵酒造の助言を基に、飲み口の角度による味わいの違いを利用し3タイプを開発した日本酒専用グラス。割れても破片を送ると新しいグラスに交換される生涯補償の付加で、グラスと使用者と職人がそれぞれ愛着と尊敬と技の継承として生涯つながる仕組みを構築した。
Based on advice from the Ichinokura Sake Brewery, three types of glasses were developed exclusively for Japanese sake, utilizing the difference in taste depending on the angle of the rim of the glass. The addition of lifetime compensation, which allows the glass to be replaced with a new one if the broken piece is sent, has created a system that links the glass, the user, and the craftsman for a lifetime of attachment, respect, and the passing on of skills.
