Takao Yo, Kinsei maki-eshi meikan (Listing of lacquer artists of recent times [Edo and Meiji periods]), Rokusho, no. 17 (1996), p. 107.
Iwasaki Kogyoku (given names Inohei or Inokuchi) was trained in the workshop of Hara Yoyusai (1772-1845) from 1839. Later he worked on repairs to the Toshogu shrine at Nikko. In the 1870's and 1880's he worked for the Kiritsu Kosho Kaisha in Tokyo and sometines used designs by the painter Kawanabe Kyosai. There are six designs by him in the Onchi zuroku, a set of more than 2500 craft-design sketches made between 1875 and 1883 as guidance to participants in international exhibitions. Of Iwasaki's six designs in the Onchi zuroku the one that most closely resembles the accessory box here is a landscape with boats in takamaki-e on a pair of sliding doors.
A paper label affixed to the storage box states that this piece was handed down in the Tokugawa family of Kii province.
