By leveraging our strengths in the entire chain from raw materials through to derivative products and tapping into value-added fields, we aim to secure stable earnings and build a framework that serves as a foundational business and supports the Group as a whole.

Basic Information

Mission of the Basic Materials domain

Starting with petrochemicals and basic chemicals, we provide materials in a wide range of fields in this business, such as automotive, housing, consumer electronics, infrastructure, and food packaging. We aim to forge a presence in Asia, secure stable earnings, and build a foundational business by providing distinctive technologies, expanding our lineup of value-added products, and further strengthening our cost competitiveness.

Business vision

We have been improving our earnings structure by steadily implementing business restructuring through fiscal 2019. The global economy has seen a major slowdown recently as a result of COVID-19, and this led to the booking of a large inventory valuation loss to reflect the steep decline in the prices of crude oil and naphtha, our key raw materials. Despite the uncertainty and volatility in the environment surrounding this business, we are striving to further deepen its operations and explore opportunities by continuing to implement thorough cost reduction, expand our differentiated products, and maintain our high operating rate by sticking to our local production for local consumption approach. In doing so, we aim to build a stable earnings base that is resistant to changes in market prices and the supply-demand balance.
