[Ed. – No special reason why this would be connected to the explosions at the U.S. Army depot in Sagamihara — unless a Japanese radical group is implicated in both. Signs aren’t pointing that way, at least as of now.]
A huge blaze broke out Monday at a steel pipe plant near Tokyo’s Haneda airport, a fire department official said, as television images showed plumes of thick black smoke and flames shooting up into the air.
The blaze came just hours after a blast ripped through a warehouse at a US military post near Tokyo, sending sparks into the sky and triggering a blaze that burned through the night, although there were no reports of injuries.
Local police declined to speculate on whether there was any link between the two incidents. …
The site near the busy international airport is owned by a unit of giant steelmaker Nippon Steel & Sumitomo Metal, which declined to make an immediate comment.
The vast steel pipe-making facility, which spans 20,800 square metres (224,000 square feet), operates a pair of manufacturing lines, about one kilometre from Haneda.
“A fire broke out from a two-metre cooling tower,” the fire official said without elaborating.
