TOKYO, Aug 27 (Reuters) - The dollar rose against the yen on Friday, trimming earlier losses due to wariness on possible measures from Japanese authorities to stem the yen's rise.
Prompting these jitters was a Kyodo news agency report saying Japanese Prime Minister Naoto Kan will hold a news conference on Friday on the government's steps to cope with a recent surge in the yen. [
]Separately, Japanese Finance Minister Yoshihiko Noda reiterated that the government will take appropriate action on currencies when necessary. [
]"The yen did dip a little bit, but I think market players were already bracing for this type of news," said Yuji Matsuura, joint general manager for Aozora Bank's forex & derivatives trading group.
Any gains in the greenback could turn out to be limited, with Japanese exporters likely to be waiting to sell the dollar on any rallies, Matsuura said.
The yen may also get a lift if Kan does not unveil any concrete steps to curb the yen's rise, Matsuura added.
The dollar was up 0.3 percent against the yen from late U.S. trading on Thursday at 84.71 yen <JPY=>.
The greenback pulled up from an intraday low of 84.27 yen as the media report on Kan's news conference sparked short-squeezing in dollar/yen, a senior trader at a big Japanese bank said.
But the pair was was still not that far away from a 15-year low of 83.58 yen hit on trading platform EBS earlier this week.
Another focus is what Federal Reserve Chairman Ben Bernanke may say on the U.S. economy when he speaks later on Friday at the annual Federal Reserve conference in Jackson Hole, Wyoming.
Investors will be watching to see whether the Fed's views on the economy have become bleaker since its policy meeting earlier in August. [
]"In addition, the market will closely watch for hints of further expansion to the balance sheet. Jackson Hole has not traditionally been a venue for major policy statements, but we do not exclude this possibility," analysts at JPMorgan said in a research note.
The Federal Reserve announced plans earlier this month to boost a flagging economy by reinvesting money from maturing mortgage bonds in government debt.
Market players say the Fed's pledge to maintain asset purchases and shift to Treasuries suggests it may boost the size of its already massive $2.3 trillion balance sheet if the economy loses momentum.
The euro inched up 0.1 percent to $1.2728 <EUR=>. It dipped to a six-week low of $1.2588 earlier this week, partly due to a renewed focus on fiscal woes among some peripheral euro zone countries. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ PDF on Japan's yen puzzle: http://r.reuters.com/nef47n Q+A-Will Japan intervene to curb yen's rise?

Despite the risk of possible action by Japanese authorities to curb yen strength such as yen-selling intervention or monetary easing by the Bank of Japan, some traders and investors say the yen could test a record high of 79.75 yen to the dollar, hit in April 1995, later this year.
The fate of the yen will depend on the overall trend of the U.S. economy rather than the possibility of BOJ intervention, Michiharu Maeda, general manager of Dai-ichi's separate account management division told Reuters in an interview on Thursday.
"The current mood of testing a record high of 79.75 (against the dollar) will stay in place in the near term," Maeda said.
"We believe that there is a big chance of the BOJ intervening by itself ... but the impact could be limited as the central bank's efforts could result in creating more chances for the market to sell (the dollar against the yen)," Maeda said.
Many analysts think solo yen-selling intervention by Japanese authorities would amount to little more than a drop in the ocean, since the driving force behind the yen's rise is mounting worry that the U.S. economy is headed for a double-dip recession and the Federal Reserve may boost quantitative easing.
A euro zone source familiar with the situation said on Thursday that joint central bank intervention to stem the rise of the yen is not likely, and that it is more realistic to expect Japan to act alone. [
