ASAHIKAWA, Japan (Kyodo) -- An adventurer from Hokkaido gave up his solo and unassisted trek Friday on foot across about 800 kilometers of Arctic ice to the North Pole due to worsening weather conditions, his support office said.

Yasunaga Ogita, 34, gave up the adventure at a point about 69 km from Ward Hunt Island, northern Canada, on the 14th day after he left there. Ogita pledged to try again next year or hereafter, according to the office.

Ogita would have become the fourth person in the world and the first in Japan to accomplish an unassisted trek to the North Pole, he said on his website.

Ogita was forced to give up as three blizzards passed since just after he set out and ice piled up ahead of him due to warm air, but he had no health problems, according to the office in Tokyo.

He planned to cover the distance from the Canadian island to the North Pole in about 50 days, pulling a 100-kilogram sleigh loaded with food and fuel.
