Japan's Nikkei share average retreated on Friday for a second consecutive session after closing at a record high earlier this week, as momentum slowed in the red-hot technology sector.

The benchmark Nikkei 225 Index sank 1.3% to close at 66,588.12, eking out a 0.3% gain for the week. The broader Topix slid 0.07% to 3,949.09.

The Nikkei closed at an all-time peak of 68,402.13 on Wednesday and has gained 34% so far this year.

The tech-heavy Nasdaq closed lower in the U.S. overnight after chipmaker Broadcom missed revenue expectations, dampening euphoria over AI investment.

On the other hand, data showing that real wages in Japan rose 1.9% in April, gaining for a fourth consecutive month, lent support to the broader market.

"While AI and semiconductor-related stocks are down today, we're seeing gains across a broad range of other sectors and stocks," said Wataru Akiyama, an equities strategist at Nomura Securities.

"Wage growth leads to increased consumption, which in turn leads to improved corporate performance, and this is thought to be contributing to the overall resilience of Japanese equities."

There were 129 advancers in the Nikkei index against 96 decliners.

The biggest laggards in the index were technology industry suppliers, with Sumco down 7.4%, followed by Ibiden , down 6.9%, and Tokyo Electron, which lost 6.6%.

The top gainers were Japan Steel Works, up 9%, followed by Trend Micro, which rose 7.3%, and T&D Holdings, up 6.4%.
