(Updates to TOCOM close)
By Chikafumi Hodo
TOKYO, Jan 22 (Reuters) - Gold fell to its lowest in nearly three weeks below $850 an ounce, as euro weakness against the dollar and sliding energy and global equity prices sparked heavy profit taking in the metal.
Gold came under pressure as some investors were selling the precious metal to cover margin calls from hefty losses made on global stock markets.
Share prices tumbled in Japan, China and India, prompting investment funds to pull out from gold and other metals, including Japanese platinum futures <0#JPL:> which fell more than 2 percent.
But traders expected gold to eventually draw safe-haven demand on overall financial market uncertainty due to fears of a U.S. recession.
"When heavy sell-offs in global stocks are happening, it's tough to buy gold," said Hiroyuki Kikukawa, analyst at IDO Securities in Tokyo.
"Gold is pressured now as the dollar is firming and stocks are plunging. In the short term, gold could be weighed down but the market is still bullish on gold in the long term," he said.
By 0850 GMT, spot gold was trading at $857.65/858.35 an ounce, down from $864.30/865.00 in late European trade on Monday.
U.S. markets were closed on Monday for the Martin Luther King Day holiday.
The spot price fell as far as $849.50 on Tuesday -- the lowest since Jan. 2. Gold was off about 7 percent from record highs of $914 per ounce hit last week.
"There are still many market bulls in gold. Funds will flow into gold once the stock market calms down," said a trader at a Japanese trading house.
"At the moment, people want to lock in profits from gold and lower exposures in commodities," he said.
COMEX gold futures slid from Friday's New York settlement. The most active February contract was down $25.20 or 2.9 percent at $856.50.
U.S. crude <CLc1> dropped more than $4 to its lowest level since early December on worries that a possible U.S. recession would slow demand from the world's largest energy consumer.
Japanese precious metals prices fell as the yen reached a 2-1/2-year high against the dollar and falls in Japanese shares depress triggered sales in gold.
The key December contract on the Tokyo Commodity Exchange fell as low as 2,911 yen a gram -- the lowest since Dec. 18.
The key contract closed at 2,954 yen, down 53 yen or 1.8 percent from Monday's close.
"Japanese retail players are unwinding positions in TOCOM gold, possibly to cover losses from the Nikkei," the Japanese trade house trader said.
Japan's benchmark Nikkei average plunged 5.65 percent to a 28-month closing low on Tuesday, its biggest one-day loss since the session after the Sept. 11 attacks on the United States in 2001, as growing fears about the U.S. economy sent global stocks reeling. [
].The Nikkei has lost more than 1,000 points and 9 percent this week.
The key December TOCOM platinum futures contract <0#JPL:> fell by its daily 120 yen limit to 5,048 yen a gram on Tuesday. The limitless frontmonth February contract closed down 163 yen at 5,144 yen.
The key TOCOM platinum contract was the lowest intraday level for any benchmark since Dec. 6.
Falls in TOCOM prices dragged down the cash price.
Platinum was at $1,515/1,520 an ounce, down from $1,537/1,542 in Europe on Monday.
