Japan's Nikkei share gauge surged past the 71,000 level for the first time on Thursday as a ceasefire deal between the U.S. and Iran boosted demand for risk assets.
The benchmark Nikkei 225 jumped 1.88 percent to 71,219.45, after touching an intraday high of 71,293.64. The broader Topix gained 1.67 percent to 4,080.26.
The U.S. and Iran released the text of an interim agreement to end their war, with U.S. President Donald Trump threatening to resume attacks and kill Iranian officials if they failed to honour their commitments.
Markets in Asia also reacted to a hawkish tilt by the U.S. Federal Reserve, which held interest rates steady. The dollar strengthened broadly, while the yen touched a near two-year low, approaching levels that prompted Tokyo to intervene in markets.
Chip-related shares led the Nikkei's gain, with Socionext jumping 9.19 percent and Screen Holdings rising 4.96 percent. Financial stocks also advanced, with Mitsubishi UFJ Financial Group up 2.44 percent. Marine transportation stocks lagged, with Nippon Yusen falling 2.08 percent.
Of the Nikkei's 225 stocks, 144 advanced while 75 declined.
