The broader Topix index of all First Section issues on the Tokyo Stock Exchange plunged 41.25 points, or 3.03 percent, to close at 1,320.15.
With the exception of construction issues, all industry categories on the main section closed in negative territory, with notable decliners comprising insurance, marine transportation and financial stock-linked issues.
