* Also helped by U.S. regulators warning banks on rate risks
* Japan finmin says markets should determine forex levels

Jan 8 (Reuters) - The dollar hit a four-month high against the yen on Friday on growing expectations that a key U.S. jobs report would point to an improving economy.
The greenback also received help from U.S. regulators urging banks to protect themselves against hikes in interest rates, supporting views that the Federal Reserves will start raising rates this year. [
]The dollar briefly dipped after Japanese Finance Minister Naoto Kan said on Friday that markets should decide currency levels, backtracking from his earlier call for a weaker yen. [
]"The biggest factor that has been moving dollar/yen is hopes of a better U.S. economy and expectations for a stronger dollar versus the yen," said Tsutomu Soma, senior manager of the foreign securities department at Okasan Securities.
The dollar edged up 0.1 percent to 77.977 against a basket of six major currencies <.DXY> <=USD>. It rose the previous day on a stronger-than-expected weekly U.S. initial jobless claims report that added to the view that the U.S. economy is continuing to improve. [
]Forecasts for payrolls have been creeping higher all week and the median is now for a flat outcome, with some as high as a 100,000 rise <ECI/US>. [
]An upbeat payrolls report would fuel talk of an early tightening from the Federal Reserve and perhaps discourage leveraged positions in carry currencies and commodities.
"The potential for the first positive non-farm payrolls print since December 2007 has the U.S. dollar in pole position, aided by its main competitors either spinning into the wall, or trying to change drivers at full speed," said David Watt, senior foreign currency analyst at RBC Capital.
The euro was little changed from late U.S. trade at $1.4312 <EUR=>, and not far from a recent low of $1.4257 struck on January 4, with investors increasingly positioning for the U.S. payrolls data.
The dollar edged down 0.2 percent from late U.S. trade to 93.20 yen <JPY=> as Japanese exporters sold the greenback and investor pocketed profits after the pair struck a four-month peak earlier in the day.
The dollar rose to as high as 93.78 yen on trading platform EBS, its strongest level since late August.
Speaking after his appointment as Japan's finance minister, Kan said on Thursday many Japanese firms were in favour of dollar/yen around 95 yen, higher than the pair traded in late 2009.
The comments raised the possibility of intervention by Japanese authorities if the yen strengthens.
The euro dipped 0.1 percent to 133.40 yen <EURJPY=R>, having hit a one-month high at 134.12 yen in early Asian trade.
