TOKYO, Aug 7 (Reuters) - Japan's Topix index closed at a record high on Thursday after worries about the impact of U.S. tariffs eased, and increased investor optimism about strong performance of domestic firms.
The broader Topix .TOPX rose 0.72% to 2,987.92. The Nikkei .N225 climbed 0.65% to 41,059.15.
Both indexes rose for a third consecutive session.
The three-day rally eclipsed a sharp decline on Monday, when the Nikkei posted its largest drop in two months.
"The market was too bearish, with concerns about the U.S. tariff impact on domestic firms. But that sentiment was reversed," said Seiichi Suzuki, chief equity market analyst at Tokai Tokyo Intelligence Laboratory.
"And the weak economic data in the U.S. raised expectations for the Federal Reserve's rate cut, which supported sentiment of both U.S. and Japanese equities," said Suzuki.
