* Japan quake, tsunami send oil, metals skidding
* Cocoa market buoyed by fears over Ivorian supplies
* Coffee prices underpinned by shortage of arabica beans
March 11 (Reuters) - Coffee fell from near a 34-year high and sugar and cocoa futures slid with other commodities after a huge earthquake and tsunami struck Japan on Friday.
The disaster pounded commodities markets, sending oil and metals prices skidding on worries about the impact on the world's third largest consumer of commodities.Coffee, sugar and cocoa futures fell with grains.
"Everything (commodities) will be down because of this quake in Japan," said Romain Lathiere, fund manager with Swiss-based Diapason Commodities Management.
"That (quake) will impact the global growth of the economy and will weigh on commodities."
ICE May arabica coffee traded down 6.10 cents or 2.2 percent at $2.7445 per lb at 1243 GMT, below the 34-year high of $2.9665 a lb touched on Wednesday. Liffe May robusta coffee traded down $83 or 3.3 percent at $2,425 per tonne.
New York coffee will fall further to $2.62 per lb next week, as a top could have formed at Wednesday's high of $2.9665, based on its wave pattern, according to Reuters market analyst Wang Tao.
ICE raw sugar futures prices fell, drifting further away from last month's 30-year highs, with tight supplies and low stocks limiting losses.
ICE May raw sugar futures traded down 0.62 cent or 2.2 percent at 28.09 cents a lb at 1246 GMT, below the 30-year high of 36.08 cents a lb touched last month. London May white sugar was down $13.50 or 1.9 percent at $714.10 per tonne in moderate volume of 2,737 lots.
"The market is still in a range and we are moving erratically within that range," said Jonathan Kingsman, managing director of the Lausanne-based Kingsman consultancy.
Dealers saw key support in ICE raw sugar futures at 27.50 and 27.00 cents a lb, and said that new physical offtake enquiries could be triggered around those levels.
ICE cocoa futures slipped, extending recent losses, trading in line with the falls across soft commodities. Unrest in top producer Ivory Coast remained a supportive factor underpinning prices.
