Masao Mimatsu
Encyclopedia
Masao Mimatsu (9 July 1888 – 8 December 1977) was a Japanese
postmaster who recorded the growth of the Showashinzan
mountain in 1944–1945.
On 31 December 1943, Mt. Showa-Shinzan began forming from rapid uplifing of a wheat field as a result of a sudden earthquake. This seismic event would eventually change into volcanic activity and result in the eruption of Mt. Usu in 1944.
Due to the Japanese war effort, basic scientific materials were unavailable. However, Mimatsu, the postmaster of Sobetsu-cho, recorded measurements and drew diagrams of the rising mountain on paper.
The story goes that in 1946, in order to study the volcano more thoroughly, he bought up the land using all of his savings and became owner of the volcano.

on Monday, 4 July 1949 (http://www.time.com/time/magazine/article/0,9171,888569,00.html) indicates this purchase to be around 1944, and to have happened as a result of pressure from the villagers of Fukaba.
Whatever the reasons, what Mimatsu gleaned from his "pet volcano" would be the basis for much understanding in years to come.
Despite his amateur status, when he presented his data and sketches to the World Volcano Conference in Oslo in 1948, his work was praised by professional volcanologists. His papers were referred to as the "Mimatsu Diagram" and for them he received the First Hokkaido Cultural Award.
In 1977, he was able to witness the third eruption of Mt. Usu in his lifetime. However, he died of illness on December 8 of the same year without being able to witness the end of the eruptive event.
He is now honoured by a statue at the base of Usuzan, and his work is celebrated in the Mimatsu Masao Memorial Hall near the site of Mt. Showa-shinzan.
