The article is devoted to the study of the historical, performing and musical aspects of the functioning of the operetta theater in the Far East in 1900–1905. The author uses materials from periodicals, most of which are first introduced into  scientific  use.  With  their  help,  the  local  specifics  of  the  performances and  facts  that  are  important  for  the  history  of  the  Far  Eastern  operetta  are illuminated:  the  opening  of  the  seasons  of  a  purely  operetta  enterprise,  the premiere of a new national operetta, and artistic compositions are established. As a result of the study, a direct perception by the Far Eastern operetta theater of the developed performing traditions of M. Lentovsky’s theater, which have become stylistic features of Russian operetta, is established. This concerns the traditions of the performance of plug-in numbers, the gradual strengthening of the  entertainment  element.  Periodicals’  testimonies  make  it  possible  to  make sure  that  the  Russian  operetta  theater  retains  all  its  peculiarities  outside  the Russian borders. After the crisis of the operetta theater in European Russia, in the Far East at the beginning of the twentieth century, it is experiencing a new heyday and retains all the developed traditions.
