Every year on May 9, Nepal celebrates Manaslu Himal Aaarohan Diwas, marking the historic first successful ascent of Mount Manaslu, the world’s eighth highest peak standing at 8,163 meters (26,781 feet). This day honors the remarkable achievement of the Japanese expedition team led by Toshio Imanishi and Sherpa Gyalzen Norbu, who reached the summit on May 9, 1956, via the northeast climbing ridge route.
The Spirit and Significance of Manaslu
The name Manaslu is derived from the Sanskrit word manasa, meaning “spirit” or “soul,” reflecting the mountain’s sacred and mystical significance. Also locally known as Kutang or Kampunge, Manaslu is situated in the Mansiri Himal range on the border between Nepal’s Gorkha and Manang districts. The mountain’s challenging terrain, unpredictable weather, and technical difficulty have earned it a reputation as one of the most demanding Himalayan peaks.
Early Exploration and Challenges
The first reconnaissance of Manaslu was conducted in 1950 by the British West Nepal Expedition led by Bill Tilman, who explored the region while focusing primarily on Annapurna. Subsequent Japanese expeditions between 1952 and 1955 made several attempts to climb Manaslu but faced natural obstacles and local resistance. In 1954, villagers from Sama Gaon initially blocked access, believing the mountain to be sacred and fearing misfortune from climbers.
After negotiations with the Nepalese government and local communities, the Japanese Alpine Club received permission to mount a pre-monsoon expedition in 1956, which paved the way for the historic ascent.
The Historic First Ascent
On May 9, 1956, Toshio Imanishi and Gyalzen Norbu successfully reached the summit, becoming the first climbers to conquer Manaslu. Their ascent was notable not only for its technical difficulty but also because it was the first time an Asian expedition had summited an eight-thousander. The team used innovative equipment for the time, including an oxygen generator that supplied climbers at high camps.
Following their success, other team members also reached the summit, and Manaslu began to attract international attention as a premier mountaineering challenge’.
Legacy and Continuing Popularity
Since that historic day, over 3,300 climbers have summited Manaslu, although many have only reached a fore summit. The mountain remains a coveted peak for experienced mountaineers, with climbing seasons primarily in autumn and spring. Manaslu’s trekking circuit is also renowned for its stunning landscapes and cultural richness, following ancient salt-trade routes and passing through traditional villages such as Samagaun, the nearest settlement to the peak.
Despite its growing popularity, Manaslu retains a sense of mystery and reverence, with local communities continuing to honor its spiritual significance.
Manaslu Himal Aaarohan Diwas on May 9 is more than just a celebration of a mountaineering milestone; it is a tribute to human perseverance, respect for nature, and the cultural heritage of Nepal’s Himalayas. The “Mountain of the Spirit” continues to inspire adventurers worldwide, reminding us of the enduring bond between people and the majestic peaks that define Nepal’s identity.
