Description from Wiki: Masataka Takayama (高山 正隆, Takayama Masataka; 15 May 1895 - 14 April 1981) was one of the most prominent Japanese photographers in the first half of the twentieth century.
Takayama was born in Tokyo, Japan. As an amateur photographer, he published many of his works in the magazine Geijutsu Shashin Kenkyū (芸術写真研究), beginning in the 1920s. He remained an active photographer even after World War II.
He was talented at pictorialist (art) photography and took many photographs using a soft focus lens and deformation and “wipe-out” techniques.
Takayama usually used a “vest-pocket” Kodak camera (a very compact folding model taking 127 film) with a single-element lens (a tangyoku lens in Japanese). These cameras (and Japanese derivatives such as the Rokuoh-sha Pearlette and Minolta Vest) were popular in Japan at the time for snapshot use, and called ves-tan (ベス単, in Japanese pronunciation besutan) cameras; “ves” coming from “vest” and “tan” from tangyoku. Takayama’s works are thus said to belong to the “ves-tan” (besutan) school. (via: wiki) (images: dassai2.p2.weblife)
