His Royal Highness Prince Nirajan Bir Bikram Shah was interested in sports, especially swimming. He was a junior swimming champion at Kathmandu’s Budhanilkantha School. Like his brother, he too wanted to contribute to the development of sports in Nepal, and was actively seeking a role at the National Sports Council.
HRH Prince Nirajan was also interested in conservation and wildlife. Inspired by his uncle, the then His Royal Highness Prince Gyanendra, Prince Nirajan wanted to start a conservation program to protect freshwater Gangetic dolphins.
