HONG KONG, June 6 (Reuters) - Japanese government bond prices fell on Friday, following a selloff in European and U.S. bonds the previous day, after the European Central Bank joined the Federal Reserve this week in expressing unusually candid concerns about inflation.
ECB President Jean-Claude Trichet jolted markets when he said higher benchmark interest rates in July were "possible," helping to lift the euro to a five-month high against the yen on Friday as dealers factored in an increasing euro zone bond yield advantage over other developed economies.
Stronger-than-expected U.S. weekly jobs data also weighed on government bonds, but helped lift stocks in Asia.
Japan's Nikkei average <
> climbed 1.6 percent to a five-month high, as investors banked their hopes for solid export growth on the back of a weaker yen and higher-than-expected sales numbers at major U.S. retailers including Wal-Mart Stores <WMT.N>.Australian stocks also rose, bolstered by shares of resource-related companies after crude prices shot up around $6 overnight as the U.S. dollar weakened against the euro.
"The backup on bonds has been quite aggressive," said Patrick Bennett, Asian foreign exchange and interest rate strategist with Societe Generale in Hong Kong.
"These inflation concerns are serious, for sure. We may be seeing the worst of it over the next three to four months. Policymakers are trying to address it," he said.
By 0200 GMT, the benchmark 10-year Japanese government bond yield <JP10YTN=JBTC>, which moves inversely to the price, rose 4.5 basis points to 1.77 percent, near a 10-month high of 1.805 percent reached last week.
The yield on the 10-year U.S. Treasury note <US10YT=RR> also ticked higher, to 4.0480 percent, within sight of the 2008 high of 4.14 percent.
Japan's Nikkei share average hit its highest since January, led by clothing company Fast Retailing <9983.T> and ceramic maker Kyocera Corp <6971.T>.
"Since the begining of this month, top financial officials in the United States and Europe have made comments that have provided support to Japanese shares," said Masayoshi Okamoto, head of dealing at Jujiya Securities.
Remarks by Federal Reserve Chairman Ben Bernanke earlier this week helped lift the dollar against the yen, one of the biggest driving factor for export-oriented Japanese stocks.
The MSCI index of Asia-Pacific stocks outside Japan rose 0.9 percent <.MIAPJ0000PUS>, though the measure was on track for its third consecutive week of declines.
Australia's S&P/ASX 200 <
> rose 1 percent, lifted by heavyweight resource firms such as BHP Billiton Ltd <BHP.AX> and Woodside Petroleum Ltd <WPL.AX>.Oil prices <CLc1> crept above $128 a barrel on Friday, as dealers put aside fears about waning global demand for the time being and focused on the dollar's weakness against the euro.
The euro held most of its overnight gains against the dollar, largely unchanged at $1.5588 <EUR=> and hit a peak of 165.61 yen <EURJPY=>, its highest since late December.
The dollar rose for a fourth straight day against the yen, which still offers among the lowest interest rates in the industrialised world. Against the yen, the dollar was up 0.2 percent to 106.10 yen <JPY=>.
Before Trichet's remarks on Thursday, Fed Chairman Ben Bernanke startled markets twice this week with pointed comments about how the weak dollar is spurring inflation and how long-term inflation expectations were a "significant concern."
The price of gold <XAU=> firmed in the spot market, ahead of the May U.S. payrolls report. It rose slightly to $878.60 an ounce, up 0.5 percent. (Additional reporting by Taiga Uranaka in Tokyo; Editing by Lincoln Feast)
