Both are female centric dramas in which the FL is pursing her career and faces set-backs and difficulties along the way. Both dramas have a similar feel.
healing slice-of-life stories set in the countryside with cinematic cooking and eating scene. personally, the cinematography of the makanai closer to korean adaptation of little forest rather than the japanese adaptation.
Both takes place in Kyoto, while one focus on the work lives in Maiko House, the other focus on the work lives in a Ryokan. Suited for those who loves Kyoto and Japanese culture.
I guess makanai-san mangaka took inspiration from it it's a classic story to begin with. There are many versions but I would choose the Haru Kuroki version anyday.
Modern times but traditional values still used. Might not be logical but when I was wounding why I liked this show besides the underdog plot.... I decided it was the traditions staying the same. This other drama popped right into my head as being the same style.
Both are a slow paced slice of life taking place mostly in the kitchen.
Nagatan to Aoto: Ichika no Ryourijou has more romance, but in both of them, the focus is on character growth and not love.
