Japan's Naomi Uemura, travelling by dog sled, becomes the first person to reach the North Pole alone.

Naomi Uemura was a Japanese adventurer who was known particularly for his solo exploits. For example, he was the first person to reach the North Pole solo, the first person to raft the Amazon River solo, and the first person to climb Denali solo.

A dog sled or dog sleigh is a sled pulled by one or more sled dogs used to travel over ice and through snow, a practice known as mushing. Numerous types of sleds are used, depending on their function. They can be used for dog sled racing. Traditionally in Greenland and the eastern Canadian Arctic the Inuit had the dogs pull in a fan shape in front of the sled, while in other regions, such as Alaska and the western part of Northern Canada the dogs pull side by side in pairs.

The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole.
