Final answer:
The term "kakushinhan" does not relate to Katsukawa Shunsho or his artwork. Instead, Shunsho was known for his realistic actor portraits, particularly in the genre of yakusha-e, depicting actors in their theatrical roles.
Step-by-step explanation:
The term "kakushinhan" is Japanese, and while it doesn't contain the word "wunder," you may be referring to a misunderstanding emanating from a popular Japanese anime or a similar source where the term has been discussed. However, in the world of Japanese art, specifically relating to the artist Katsukawa Shunsho, the term "kakushinhan" does not directly apply. Katsukawa Shunsho was celebrated for his yakusha-e prints, particularly vivid depictions of actors like the renowned Ichikawa Danjūrō V dressed in character. For instance, Ichikawa is depicted in the fearsome role of Hannya no Gorō, complete with a dramatic costume and makeup. These actor portraits were known for their realism and dramatic portrayals, capturing the essence of the performer and their character in the Edo period of Japan.
