TOKYO — Japan has transitioned to being a net importer of basic petrochemicals, a shift driven by soaring naphtha prices linked to supply disruptions caused by the ongoing conflict in Iran. Petrochemicals, essential for manufacturing products like plastics, were traditionally produced domestically from crude oil-derived naphtha. However, the surge in naphtha costs has made importing these chemicals from neighboring countries such as China and South Korea more economical.

This strategic pivot allows Japanese companies to better adjust their procurement in response to downstream demand fluctuations. The disruption in naphtha supply has thus reshaped Japan’s petrochemical market dynamics, emphasizing regional trade within Asia.
