Both revolve around noble, morally just “outsiders” from their respective organizations investigating and correcting corruption in bureaucracy and politics.

Both these drama center on a traditional Japanese family in which the female lead has to uphold responsability as the daughter/daughter-in-law for the family's prestige.

While Fukuyado Honpo is more about the relationship between the female lead, her mother, sisters and love interest ; ETnTS us about a mothe-in-law/daughter-in-law relationship.

"Kohiya No Hitobito" and "Mayonaka no Panya-san" are made for different marketing audiences, however, they both give off the same air and are roughly in the same genre. Each show has a wonderful cast and both have a very unique story to tell!
