Naomi Uemura (植村 直己, Uemura Naomi, February 12, 1941 – disappeared February 13, 1984) 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.

Before his 30th birthday, Uemura had solo-climbed Mount Kilimanjaro, Aconcagua, Mont Blanc, and the Matterhorn, had walked the length of Japan, and summited during the first (1970) Japanese expedition to climb Mount Everest and subsequent disastrous 1971 International Everest Expedition.

Naomi Uemura was a licensed radio amateur operator, signed as JG1QFW. He used amateur radio communication during his expeditions.^[2]

Uemura was born in Hidaka, now part of Toyooka, Hyōgo, Japan, to a family involved in agriculture. He was the youngest of seven children. In April 1960, he entered the Department of Agricultural Manufacturing at Meiji University's Faculty of Agriculture, and joined the mountaineering club. Shy, he began climbing in college in the hope that mountaineering would increase his self-confidence.^[3]

In 1964, 23-year-old Uemura left Japan with $110 USD (approximately $1000 in 2023 money) and boarded a ship to Los Angeles on a tourist visa. Then, he worked on a farm near Fresno, but was soon discovered by the immigration officials; even though he avoided deportation, he was told to stop illegal employment and leave the country. Later, he boarded a ship to Le Havre, France on October 20, 1964 from New York, and arrived at Chamonix later that month.

On November 10, he attempted to climb Europe's highest peak, Mont Blanc (4,807 m above sea level), solo. On the third day, he fell into a hidden crevasse on the Bossons Glacier; luckily, he survived. At the end of the same year, he took a job as a ski patroller at the Avorias ski resort in Morzine, near the Swiss border, run by Olympic alpine ski racer Jean Vuarnet, to earn money and use it for his mountaineering journey.

After 2 months of working there, in 1965, he temporarily left the job to join the Meiji University mountaineering club to hike in the Himalayas and traveled to Kathmandu, Nepal. They hiked Cho Oyu and camped on Ngozumpa Glacier along with Sherpas and successfully reached the peak.^[4]

In September 1966, he travelled through Kenya to hike Mount Kilimanjaro and Mount Kenya. After coming back to Avorias that November, he set the 1967 goals to visit Greenland, hike Aconcagua solo, and continue improving his French and English.

Uemura travelled to South America from Spain in December 1967 to hike Mount Aconcagua solo. Unconvinced that he was capable, the local officials told him to obtain military permission, a guarantor, and an agreement from the Japanese embassy in Argentina; members of the hiking association in Mendoza offered to be the guarantor, and while he was waiting for the military permission, he went to hike Cerro El Plata (altitude 5,968 meters) to demonstrate his abilities. He also summited an unnamed mountain peak in Argentina, and named it "Meiji", after his alma mater, Meiji University.

After successfully summiting Aconcagua, in April 1968, he came to Iquitos, Peru and rafted 6,000 km solo along Amazon River for 60 days, to Macapá, Brazil.

After flying from Brazil to the United States, he came to California again to work at a fruit factory and visited Alaska, attempting to climb Denali. He was not able to get a hiking permit, so he hiked Mount Sanford instead.

In 1968, Uemura returned to Japan briefly, then went to Mount Everest twice.

Uemura wrote that he almost gave up twice during his 1978 North Pole trip. On the fourth day of his trek, a polar bear invaded his camp, ate his supplies, and poked his nose against the sleeping bag where Uemura lay tense and motionless. When the bear returned the next day, Uemura was ready and shot him dead. On the 35th day of the trip, Uemura had hunkered down on an ice floe with his malamutes, when there was the roar of breaking the ice and the floe cracked into pieces. He and his dogs were stranded on a tossing island of ice. After a night of terror, Uemura found a 3-foot-wide (0.91 m) ice bridge and raced to safety.

He persevered and became the first person to reach the North Pole solo. Describing his 57-day push, he wrote, "What drove me to continue then was the thought of countless people who had helped and supported me and the knowledge that I could never face them if I gave up." In this trip, he cooperated with the Canadian Air Force and received his supplies from its helicopters. After the trip, he questioned such extensive support and decided to carry supplies on his own back.

After the North Pole trip Uemura became the first person to complete a dogsled journey down the entire length of the Greenlandic ice sheet. He completed the trip from May 10 to August 22, 1978. A commemorative plaque is located in Narsarsuaq in the south of Greenland.

The mountain of Nunatak Uemura in Greenland was named in honour of him. Uemura chose the pinnacles as the ending spot of his 1978 crossing of the island.^[5]

In August 1970, Uemura climbed Denali (then known as Mount McKinley) solo, becoming the first person to reach the top alone. He did this quickly and with a light pack (8 days up, versus an average of 14 days or so; 55-pound (25 kg) pack, versus an average probably twice that). August is after the end of the normal climbing season. While the weather he faced was not terrible, the mountain was almost empty with only four other people on it. Though many people have climbed Denali alone since Uemura, most do it in the middle of the climbing season.

Uemura dreamed of soloing across Antarctica and climbing that continent's highest peak, Vinson Massif. In preparation, in 1976 he did a solo sled-dog run from Greenland to Alaska, in two stages and 363 days.^[6] He set a record for the long-distance record for a dog-sled journey at 12,000 kilometres (7,500 mi).^[7]

Uemura then prepared to climb Denali again solo in winter; however, for people unfamiliar with Alaskan climbing, the difficulty of a winter ascent can often be misjudged. Nobody had successfully climbed any large Alaskan peak in winter until 1967 when Gregg Blomberg organized an expedition that got to the top of Denali (Blomberg himself did not summit). This team lost one member and nearly lost the remaining members in a storm on the way down. Team member Art Davidson's book, Minus 148, recounts the events of the climb and was named after the storm that jeopardized the team.

There is a high degree of danger with glacier travel, and even short treks across the ice are considered hazardous. For example, glaciers are often broken with cracks, called crevasses, that are often covered with snow and not visible. Due to these occurrences as well as other underlying factors, an ascent is both very difficult and very dangerous to attempt without a team.

Uemura had developed a "self-rescue" device which consisted of bamboo poles tied over his shoulders. The poles would span any crevasse into which he fell and allow him to pull himself out. He planned a very light run, with only a 40-pound (18 kg) pack plus sled. He kept his gear light by planning to sleep in snow caves and therefore freeing himself from needing to carry a tent. He also skimped on fuel and planned to eat cold food.

He began his climb in early February 1984 and reached the summit on February 12. Sometime later, climbers would find the Japanese flag that he left at the summit.^[8]

On February 13, 1984, one day after his 43rd birthday, Uemura spoke by radio with Japanese photographers who were flying over Denali, saying that he had made the top and descended back to 18,000 feet (5,500 m). He planned to reach the base camp in another two days but never made it.

There appeared to be high winds near the top, and the temperature was around −50 °F (−46 °C). Planes flew over the mountain but did not see him that day. He was spotted around 16,600 feet (5,100 m) the next day (presumably on the ridge just above the headwall). However, complications with the weather made further searching difficult.

It was likely that Uemura was running out of fuel at this point, but because of his reputation, nobody wanted to send a rescue party for fear it would offend him. Doug Geeting, one of the bush pilots who had been "Uemura spotting" over the previous week, said, "If it were anybody else, we'd have somebody [a rescuer] on the mountain already". On February 20, the weather had cleared, and Uemura was nowhere to be found. There was no sign of his earlier camp at 16,600 feet (5,100 m) and no evidence that caches left by other climbers nearby had been disturbed.

Two experienced climbers were dropped at 14,000 feet (4,300 m) to begin a search. Though another storm came in, they stayed on the mountain until February 26, finding a cave in which Uemura had stayed at 14,000 feet (4,300 m) on the way up, but no sign of Uemura himself. A diary found in the cave revealed that Uemura had left gear there to lighten his load on the summit push. He had also left his self-rescue poles back at 9,500 feet (2,900 m), knowing he was past the worst crevasse fields. Most people figured he had fallen on his descent of the headwall and been hurt, died, and was buried by snow. Another theory is that he could have made it to 14,200 feet (4,300 m) (which is the base of the headwall) and then fallen into one of the many crevasses there and perished.

A group of Japanese climbers arrived to look for the body. They failed, though they did locate much of his gear at 17,200 feet (5,200 m).

The diary found in the 14,000 feet (4,300 m) cave has been published in Japanese and English. It describes the conditions that Uemura suffered—the crevasse falls, −40° weather, frozen meat, and inadequate shelter. The diary entries showed him to be in good spirits and documented the songs he sang to stay focused on his task.

The last entry read, "I wish I could sleep in a warm sleeping bag. No matter what happens I am going to climb McKinley."

Uemura gave frequent public lectures and wrote about his travels. His adventure books for children were popular in Japan. There is a museum dedicated to him in Tokyo^[9] and another in Toyooka, Hyōgo.^[10]

His alma mater, Meiji University, awarded him an honorary doctorate in June 1984.^[11]

He was posthumously awarded People's Honor Award.^[12] An award named for him, Naomi Uemura Prize, was created in Japan after his death, to honour outstanding adventurers.^[13]

An adventure-drama movie about him, "Lost in the Wilderness" (Japanese: 植村直己物語, Hepburn: Uemura Naomi monogatari, "The story of Uemura Naomi") was released in 1986.^[14]

He is remembered not only as a gifted climber and a driven adventurer but also as a gentle, self-effacing man who cared about others. In the words of author Jonathan Waterman, "[Just as remarkable] as his solo achievements were his sincere modesty and unassuming nature. Another part of his greatness lay in his deep interest in everyone he met."^[15]
