Overview

Ishizuka Glass is a leading manufacturer of glass containers and plastic containers founded in 1941, strategically shifting to PET bottle and paper container production to lead the industry.

Current Situation

Ishizuka Glass recorded consolidated sales of 71.1 billion yen and net assets of approximately 27.6 billion yen in 2019. Amid the shrinking glass bottle market, it is advancing business transformation by focusing on PET bottle and paper container manufacturing. Its mainstay PET bottle preforms are supplied to major beverage makers such as Japan Coca-Cola, establishing a stable revenue base. In 2021, it posted operating losses for the third consecutive period due to declining glass bottle demand and the impact of COVID-19, closing the Himeji plant and optimizing its production structure. Although the holding company transition plan was postponed, it is focusing on reorganizing group subsidiaries and strengthening recycled PET production. Moving forward, it aims to develop environmentally friendly containers and recycling businesses as growth pillars, building a sustainable manufacturing system. It is also pursuing new market development through diversification into paper products and plastic containers to achieve recovery to stable management.
