both involve the main character going back in time to the warring states period, and both have advanced future knowledge about a skill, in Nobunaga no Chef its cooking and in jin its medicine.
These manga are time slip manga with ultra realistic themes and stories, they're slice of life in nature but take their time to explore Japanese history to introduce high stakes melodrama that keep the story from going stale. While Nobunaga no Chef is about a Chef entering a time slip, Jin focuses on a modern day brain surgeon. Both characters use their knowledge and professional skills to better the worlds of those around them as well as help cement themselves in their current predicament so that they can survive life in the distant pass easier than before.

Same time leaper idea, both clearly remember how to do their job and use it to help people in the time that they leaped too. Both too, develop interest and curiosity for the reader "What will this man do in that time? How do they do that? and What is going happen to them?"
