The article includes a biographical essay of Professor Akira Osawa (Japan) and a brief analysis of his scientific legacy. A. Osawa was born and raised in the post-war period, which became the period of the formation of a sovereign Japanese state and its tremendous economic growth (Japanese economic miracle).

His scientific research was focused on self-thinning phenomenon, stand growth and development, natural catastrophic disturbances and their consequences, and ecosystem carbon dynamics. Boreal forests in North America, Siberia and Scandinavia have been the major subjects of his studies. The main achievement of A. Osawa’s investigations was the new method proposed for quantitatively (stand density and stem parameters) reconstructing structural development over time of even-aged monospecific forests and applied to a larch (Larix gmelinii (Rupr.) Rupr.) stand in the permafrost zone of Siberia. It relies on samples obtained from one-time observation that is of great importance for vast Siberian territories.
