TOKYO, July 17 (Reuters) - Japan's Nikkei share gauge

tumbled more than 3% on Friday as a global rout in chipmakers

and an escalation in Middle East tensions prompted investors to

shun risk assets.

The benchmark Nikkei 225 was down 3.6% at 64,443.84.

The broader Topix slipped 2% to 3,950.08.

The decline followed overnight losses in U.S. equities,

where technology stocks tumbled despite upbeat local economic

data and a strong start to corporate earnings season.

"The market appears to be swayed by high earnings

expectations for semiconductor-related companies," Sony

Financial Group analysts said in a note.

Hawkish remarks from Fed officials on Thursday reinforced

expectations for further U.S. rate hikes. Geopolitical tensions

also remained elevated, with U.S. President Donald Trump

threatening a broader escalation in strikes on Iran.

Advancers in the Nikkei 225 were outnumbered by decliners by

132 to 92, while one stock was unchanged.

Kioxia Holdings ( KXHCF ) was the index's biggest percentage

loser, tumbling 16.05% for its steepest one-day decline since

November 2025. Shares of Taiyo Yuden ( TYOYF ) fell 15.45%, while

Screen Holdings ( DINRF ) lost 11.45%.

Shift was the index's top percentage gainer, rising

6.59%, followed by Seven & I Holdings ( SVNDF ), up 4.38%, and

Nichirei ( NCHEF ), which gained 4.29%.
