Notes

December 2025 news confirms Seibu Oil is closing the Yamaguchi Refinery. The facility is transitioning from active refining operations to conversion into a different facility type (carbon-free energy hub). The closure announcement supersedes the previous 'under_construction' status which referred to the conversion project itself.
