Kanō Norinobu (狩野典信): the Kobikichō house at its peak
Kanō Norinobu (狩野典信, 1730–1790) was a Japanese painter of the middle Edo period and head of that Kanō lineage descending from Kanō Naonobu. His art name was Eisen'in (栄川院). The characters 典信 allow two readings – Norinobu and Michinobu – both referring to the same painter.
Origin, adoption, and career of offices
Norinobu was the son of Kanō Furunobu and was adopted by Kanō Gennobu at the age of two – within the Kanō houses a common practice by which succession was secured. His career advanced steeply: in 1762, at the age of 33, he received the clerical honorary rank of Hōgen, and in 1780 the higher rank of Hōin. In addition, he held the court title of Chūmukyō. In 1777 he was assigned a new residence in the Kobikichō district; after this place the lineage – retroactively as far back as Naonobu – is referred to as the Kobikichō-Kanō house.
Renewal through the Chinese approach to line drawing
Norinobu's art-historical significance lies in a deliberate course correction. In the 18th century, the Kanō school was regarded as rigid: transmission through model sheets had led to a painting style that was technically assured but lacked vigor. Norinobu countered this with a return to the vigorous line drawing of Chinese painting, seeking to restore the school's capacity to act along this path. Under him, the Kobikichō house became the most successful of the four Oku-eshi houses, that is, the highest rank among the shogunate's painters. His son Kanō Korenobu succeeded him.
Rank titles as an aid to dating
The clerical honorary ranks of Hōgen and Hōin, conferred upon painters of the shogunate, appear regularly in the signature — which makes them practically useful. A sheet signed with the Hōin title can, in Norinobu's case, have been made no earlier than 1780; if it bears the Hōgen title, it dates between 1762 and 1780. Because the Kanō houses worked across generations with similarly formed names — Naonobu, Norinobu, Korenobu, Naganobu — this combination of name character and rank designation is often the most reliable clue when comparing several works.
