Message from the president

PS Japan is a pure-play polystyrene (PS) manufacturer established in 2003 through the integration of A&M Styrene Co., Ltd. (PS joint venture of Asahi Kasei Corp. and Mitsubishi Chemical Corp.) and the PS business of Idemitsu Petrochemical Co.,Ltd (now Idemitsu Kosan Co.,Ltd.).

Ever since our establishment, we have maintained our position as Japan’s leading PS company through continuous effort for effective management and with the unwavering support from our customers.

Our business philosophy has remained unchanged since the establishment of A&M Styrene; we always think from the perspective of our customers, emphasizing trust, reliability, and value provision. Based on this philosophy, all personnel of PS Japan are united by our mission for reliable product supply, stable product quality, the creation of products with new value and sincere approach to environmental issues.

We see the Asian market as the key for our future growth, and so we aim to continue to be a leading manufacturer of PS products that widely recognized throughout Asia. We look forward to your ongoing support.

President
