Born to peasant parents in Tüsheet Khan Province (present day east central Mongolia) in 1895, Danzan traveled to Japan in 1916, thus earning the moniker he carried later in life to distinguish him from his contemporary namesake, party leader Soliin Danzan.
After serving again as party deputy chairman from 1924 to 1925, he became a diplomatic envoy with postings in Soviet Russia (1925-1926) and then to China (Beijing, Shanghai, Tianjin, Nanjing, and Harbin) from 1926 to 1928.
From 1929 to 1931, he worked at the Institute of Manuscripts alongside Prime Minister Anandyn Amar.
In 1932, Danzan was caught up in a widescale purge of suspected rightwingers (mostly politicians who voiced concerns with growing Soviet influence in Mongolia) that included Jamsrangiin Tseveen, Tseren-Ochiryn Dambadorj, and Navaandorjiin Jadambaa.
Danzan was arrested and charged with counterrevolution for allegedly collaborating with Japanese intelligence as his nickname suggested.
