TOKYO (Reuters) -Japan's Nikkei share average scaled its highest levels since February 1990 on Thursday, as a weaker yen buoyed exporters and caution over an impending hike by the Bank of Japan continued to fade on the back of weak wage data.
The Nikkei rose 1.77% on its third straight day of gains this week, closing at its highest in nearly 34 years at 35,049.86. The index was also on its way to the largest weekly gain since late March 2020.
The broader Topix rose 1.57% to end at 2482.87.
The strong earthquake that hit western Japan last week and lacklustre wage growth data are forcing market participants to "reappraise" when the Bank of Japan (BOJ) will normalise its monetary policy, said Tony Sycamore, a market analyst at IG.
Workers' real wages shrank for a 20th straight month in November, according to data published on Wednesday, confounding officials' wishes to see wage gains before tightening policy.
"That (wage data) gave the Nikkei the excuse to pop up there, towards that 35,000 level," said Sycamore, adding the index "probably can continue to make good gains while we try and work out when the BOJ can look to take its next step."
The yen fell 0.9% on the U.S. dollar overnight in the wake of the data and was hovering around 145.52 during Asian trading hours. [FRX/]
A weaker yen tends to support exporter shares, increasing the value of overseas profits in yen terms when firms repatriate them to Japan.
