The 12 sepia tone (untinted/colored) albumen photographs that follow are attributed to Ogawa Kazumasa. They all are images relating to the Iyeyasu Temple in Nikko. Most are interior views but some are outside views of the temple structures. All the photographs are sepia tones (untinted). They measure 8~8 1/4+ x 10~10 1/2+ in (ca 21 x 27 cm) and are mounted one side only to thick card stock measuring 16 x 13 in (40 x 33 cm). The mounts have four rounded corners and do not appear to have been extracted from an album. It appears that these were issued in loose folio form. On the back of each there is a pencil notation stating "Japan - Nikko, set of 21 photographs."

Since the majority of the images were first published by Ogawa in 1892, that is believed to be the approximate date that these 12 photographs were marketed.

In the captions you see the "Iyeyasu Temple" or "Iyemitsu Temple." I believe that this location is now refered to as the "Ieyasu Temple" and that is a part of the Tosho-gu Temple complex which was build to house the remains of Tokugawa Ieyasu (1543 - 1616).

Ten of the 12 images appeared in the K. Ogawa's albums referenced and linked below. The other two are believed to be K. Ogawa because of the numbering, type of photograph and image shown (views in the Iyeyasu Temple).

Terry Bennett in Old Japanese Photographs, Collectors Data Base* lists 70 numbered photographs which he attributes to Ogawa Kazumasa. These photographs span the numbers between 1 and 344. The majority of these are temple views but the temple name is not specified. Only one of the the numbers in this unit of 12 photographs is listed. No. 55 is listed by Bennett as "Temple Wall Panel." While the title on the photograph is "Inside Iyemitsu Temple, Nikko" the image is of a room with many carved wall panels.
