Abstract
We describe the history and the present state of the Official Residence for the Commander of Karafuto-Guards, which was completed in 1908. We also deal with its suspected designer, Army Architect Yasushi Tamura (1878-1942), who is known as the designer of the Divisional Headquarters Office of the Imperial Guards. The official residence has high value in the modern architectural history not only because it is one of the oldest buildings of the Japanese colonial period in Sakhalin, but also because it was a dwelling house built for the people of highest class in Sakhalin.
