If you like Yabushige's character in Shogun, you may like Sanadamaru. This Taiga Drama shows a "sneaky" side of a samurai during the end of Sengoku Era, where they have to cleverly "switching sides" for the clan survival.

Sanadamaru also depicts the life of Taiko in his later years and how Ishida (Lord Ishido in Shogun) was desperately trying to corner Tokugawa (Toranaga) to the Sekigahara battle. The drama spans until the fall of Osaka castle.

Bonus: Ninja action, Christian depiction, Hosokawa Garcia (Mariko) appearance

- same plot but with an historical setting.
- very similar characters setting
- still unique because they adapted it

If you want to know the sentiment towards Taiko during his later years, Gunshi Kanbei has good depiction of it. This is important to understand why conflicts between Ishida and Tokugawa exist in the first place. Gunshi Kanbei is 85% following history while Shogun is 95% fiction.

Similarities: Kanbei was a Christian samurai so you will get good depiction of Japanese Christian during the time. However Kanbei character has not represented in Shogun.

Downside:
1. Gunshi Kanbei span over 50 episodes
2. Gunshi Kanbei doesn't focus much on Tokugawa (Toranaga in Shogun)
3. Gunshi Kanbei can't match the Shogun budget

This about young adult sport and romance. Not to heavy and so much tears falling.
Some funny that can make you laugh and can enjoy your coffee while watch your drama.
All the cast doing a good job! ?

If you want to know more about Japan politics especially the conflicts after the death of Taiko, Aoi has the best depiction and it is also one of the best and comprehensive drama discussing Battle of Sekigahara, which is the final moment in Clavell's Shogun.
The difference is Aoi follows 90% of the actual history while Shogun as we know does not.

Bonus: Miura Anjin (Blackthorne) does have an appearance in Aoi

Downside:
1. Aoi is 49 episodes long and span over the 3 generations of Tokugawa
2. Aoi has low budget compared to Shogun for obvious reason
3. Aoi has old actors playing younger role

Both have a Republican Era setting and are about the FL seeking revenge on a powerful man who destroyed her family, but in the process she ends up falling in love with the man's son.

Bl love story between the dentist and the patient. Very cute characters, a lot of shenanigans. Sweet tooth isn't even out yet, but it seems like a remake of My Tooth your love even judging by the trailer.

Also involves complex time loops and traveling to the past to discover love. Acting is excellent and overall plot is angsty and satisfying. Not as comedic as Lovely Runner.

Both Sweet Tooth, Good Dentist and Fish Upon the Sky are based in a university setting with one of the main characters being a student in the Faculty of Dentist.

If you liked Shogun, you might also like Six Flying Dragons (SFD). Besides the obvious differences—one is a K-drama, the other an American production, and one has 50 episodes and the other 10—there are many similarities. Both are about the rise of authoritarian leaders. Like Shogun, SFD is very well written and acted out, and there is a mix of real-life and fictional characters.

However, the main difference is that SFD does not use any historical revisionism, neither character nor plot. Historical events are followed to the letter, both the glory and gore.

Age gap between ML and FL, arranged marriage with a general that gradually turns into a true romance. FL is a concubine’s daughter in a family that uses her and mistreats her.

dark, school drama to keep you on your toes. Great quality and great cast. If your looking for a drama to binge this will really have you sitting on the edge of your seat.

Both dramas feature the slice of life genre with a warm, rich cast where even the ensemble roles are lovingly developed. Both feature romance, especially romance between reunited childhood friends. Cinematography features warm colors and intimate shots. Mix between emotional and soothing OSTs. Both are feel good shows.
