TOKYO, Sept 11 (Reuters) - Japanese stocks rose on Tuesday, with exporters lifted by the yen's weakening against the dollar and technology shares taking heart from gains in their American peers.

The Nikkei share average .N225 was 0.91 percent higher at 22,575.43.

During morning trade the index briefly touched 22,614.87, its highest since Sept. 5.

"The yen's depreciation is the key driver, with gains by the S&P 500 and Nasdaq providing additional support," said Yutaka Miura, senior technical analyst at Mizuho Securities.

"Trade friction remains a concern, but the United States is yet to activate the tariffs on 200 billion dollars worth of Chinese imports, allowing for some short covering to kick in and lift the Nikkei."

The yen JPY= slipped against the dollar for the third day, lifting exporters.

Toyota Motor Corp 7203.T rose 1.8 percent, Panasonic 6752.T gained 0.9 percent and Tokyo Electron 8035.T was up 1.6 percent. Bridgestone Corp 5108.T added 0.5 percent.

Technology shares climbed as their U.S. counterparts bounced overnight following last week's large losses, with the tech-heavy Nasdaq .IXIC climbing 0.3 percent.

Renesas Electronics Corp 6723.T was up 5.7 percent after the company said on Tuesday it had agreed to buy U.S. peer Integrated Device Technology Inc IDTI.O for about $6.7 billion, aiming to boost its expertise in self-driving car technologies. nL3N1VX1I4

Shares of Kaga Electronics Co 8154.T rose 5.5 percent after the semiconductor manufacturer announced that it would buy Fujitsu Electronics from Fujitsu Semiconductor for 20.54 billion yen ($184 million). Inc 6387.T , a manufacturer of equipment used to make electronic components, gained 5.1 percent after reporting strong earnings, with sales for the year through July 2018 surging 74.9 percent from the previous year to 5.47 billion yen.
