I believe these photos were taken by Takahiro Bessho. See: http://en.rocketnews24.com/2015/11/12/japanese-photographer-brings-out-the-beauty-of-airports-and-factories-in-gorgeous-night-images/
Here are some that include Japanese text: doseng.org/foto/55450-yaponskie-zavody-34-foto.html The tanks are labeled セントラル硝子 which is the Central Glass company: cgco.co.jp/ Below that is says 塩ビモノマー (vinyl monomer), whatever that is.
