TOKYO, June 12 (Reuters) - Japan's Nikkei index jumped more than 4 percent on Friday as investors rushed to buy shares amid renewed hopes that the conflict in the Middle East might end after U.S. President Donald Trump called off strikes against Iran.

The Nikkei rose 4.06 percent to 66,822.56 points by 00:25 GMT. The broader Topix index advanced 2.2 percent to 3,914.74 points.

Trump said on Thursday that the United States and Iran could sign a peace agreement early next week, which would reopen the Strait of Hormuz to shipping, but Iran responded that it had not reached a final decision on the agreement.

Technology stocks led the Nikkei's gains, with shares of chipmaker Advantest and Tokyo Electron jumping 8.8 percent and 10.49 percent respectively.

Shares of memory chip maker Kioxia gained 5.94 percent. Shares of technology investor SoftBank Group advanced 3.34 percent.

But shares of recruitment firm Recruit Holdings and Sony both fell by more than one percent.

All but four of the 33 sub-indices on the Tokyo Stock Exchange rose. The mining sector index fell 1.02 percent, making it the worst performer.
