TOKYO, April 3 (Reuters) - Japan's Nikkei share average

slumped more than 4% on Thursday, plunging to an eight-month

low, after U.S. President Donald Trump revealed a broad set of

reciprocal tariffs, including a 24% levy on Japanese goods.

The Nikkei slumped as much as 4.6% in early trading,

dropping to 34,102.00 for the first time since August 7.

The broader Topix lost as much as 4.3%.

Of the Nikkei's 225 components, 217 were in the red, while

just eight showed gains as of 0020 GMT, 20 minutes into the

trading day.

Banks were the worst performers among the Tokyo

Stock Exchange's 33 industry groupings, sliding 6%, as a sharp

decline in bond yields at home and abroad darkened the outlook

for income from lending and investing.

The bourse's automaker sub-index dropped 3.3%,

with additional tariffs on car exports to the U.S. set to go

into effect later on Thursday.
