Osamu Yamamoto is one of the most highly esteemed collotype printers working today. His is the head of the Collotype Institute of Benrido Inc, Kyoto, Japan.

Benrido was established in 1887 as a small rental bookshop which evolved into a well established fine-art photography department, printing and publishing company. Dedicated to the preservation and dissemination of cultural heritage, Benrido, Inc. works in the reproduction of cultural heritage for preservation, printing and publishing of fine art publications and prints by offset and collotype processes, museum marketing, product and retail space management, as well as in the imaging of cultural heritage for conservation. In the 1880s, the collotype printing process was introduced to Kyoto and by 1905 Benrido had begun producing collotypes. Collotype is one of the earliest forms of printing techniques and was invented in France in 1855 by Alphonse Poitevin as a method for photographic fine art printing. Due to the high level of print and archival quality, it has since been used primarily as a way to reproduce and preserve Japan’s National Treasures and cultural properties. Today Benrido Collotype Atelier remains as one of only a few studios left in the world capable of producing fine colour collotype prints.
