So says NBC News:

OSAKA — Explosions at a chemical plant in Hyogo Prefecture on Saturday killed a firefighter and injured dozens of people, the Japan Times reported, citing local fire department and police officials said. Global production of diapers could be affected because the plant made a key ingredient in a resin used in them, Japanese media reported.

Let me go out on a limb here and suggest NBC News is being slightly sensationalist in its coverage.
