Different plots but both dramas have bratty girl character and due to certain circumstances an adult have to stay and take care of her.

Female leads in both dramas are Plain Jane. Their "strict and stylish" female bosses would later change them into Stylish Jane.

Both dramas portray Ieyasu as the protagonist, but Aoi is only focusing on the older Ieyasu (to be exact after Hideyoshi death). Both dramas however have different interpretations on the character, where TI is more on the whitewash version, while Aoi is skewed towards the "gray-character" which in my opinion more tally with the historical records.

The main character in both movies had to confront with someone out of their league (in terms of fist fighting) for the sake of the woman they love. Both are adapted from "seinen manga" and good at portraying the anger and frustration of the main characters.

Aoi is another portrayal of Gou-Hidetada marriage life. However Aoi started off with both of them already married (i.e. it will not start from their childhood) and focused more on the affairs around Tokugawa big family as well as more details on Edo shogunate administrations.

Both focus on Sankin Kotai and how it drains out Local Clan financial. If you're interested in this old Japanese samurai tradition, Ichiro will tells more on what is needed for a Sankin Kotai. Although there are differences between the two, where the time-line for Choukosaku was during the early implementation, while Ichiro was at a more later date.

Since Kuroda Kanbei was the strategist for Hideyoshi, both dramas will share many similarities. Gunshi Kanbei tells more in depth on the western politics and spans until Sekigahara War. Takenaka Naoto also played as Toyotomi Hideyoshi in Gunshi Kanbei. Although the writing for the character was a bit different.

Toshiie and Matsu (TAM) is like a spin off of Hideyoshi in terms of writing, but told from the perspective of Toshiie/Matsu. Character of Matsu in TAM was much more like One in Hideyoshi.

Both dramas revolved around people of Satsuma Domain during Bakumatsu period, with mostly similar characters but written from different perspectives. Some actors in Atsu-hime also appeared in Sego-don but with different roles.

Both dramas combine sport and business themes into one, and based on novels of the same writer. The plots are different though, where Roosevelt Game has "parallel sport-business story" but No Side Game is a more directly connected sport-business kind of story.

Surprisingly no one is recommending this yet. Both dramas are written by the same screenwriter. While Confidence Man JP is about conman and Legal High is about law, main leads in both dramas share similarities. Dako (Nagasawa) is the female version of Komikado (Sakai), and Boku-chan (Higashide) is the male version of Mayuzumi (Gakky).

Both drama have parallel sport and business plots combined together, in the sense that business maker got inspired by the sportsmen fighting spirit to save their company from collapsing. Both are based on Ikeido Jun's novel and produced by TBS, so the viewer will get the similar feel and vibe. There are also technical stuffs being discussed in both dramas in particular how investment in RnD and having the right expertise can distinguish a company from it's much bigger rival.
