In the essay Kiyūshōran (嬉遊笑覧), literary and cultural scholar Kitamura Nobuyo (喜多村信節) states that "Things of custom unusual to the past tend to be called 'nanban'".
Bukkake soba (ぶっかけそば), eaten with a hot soup based on soy sauce and flaked bonito, became widespread in the middle of the Edo period.
The addition of duck and Welsh onions in the manner of kamo nanban is considered to have been started by the Sasaya (笹屋) restaurant in the Shibakuro-chō area of Nihonbashi.
[5] Kamo nanban using about five one-inch pieces of Welsh onion, cut vertically and fried, then boiled with duck, is said to have met the tastes of the time and thrived.
[12] Also in Morisadamankō (守貞謾稿), a work with detail of the Mores of the closing days of the Tokugawa shogunate, Kamo nanban is introduced as "Duck with onions.
[15] In "I am a cat", there is the expression "the ingredient of kamo nanban is like as chicken; the lodge's beef hotpot is like as horse meat" (鴨南蛮の材料が烏である如く、下宿屋の牛鍋が馬肉である如く).
In some instances, they are only warmed briefly in soup before being added, but frying or roasting in sesame oil is considered to be correct.
In the 9th episode of the TV drama series "Kurosagi", the kamo nanban cup noodle eaten by the main character was an original version of the show.
