A Dow Chemical plant north of Tokyo that makes ion exchange resins used for water treatment experienced flooding, but there were no reports of injuries or environmental damage. The facility was built in 1993 by Rohm & Haas, which Dow acquired in 2009. Dow has 31 facilities in Japan, and a spokesman said limited  communication was making it hard to gauge the full impact.

DuPont, which has a large petrochemical joint venture with Mitsui Chemicals Inc in Japan, said some ceiling tiles fell at a Tokyo office. The company also reported minor damage to ceilings, walls and windows, as well as some piping at its engineering polymers facility in Utsunomiya, Japan. No injuries were reported.
