Almost identical, Reversal Orchestra if you want comedy or Sayonara Maestro if you want family drama.

- Buddy Cop drama
- Both Male lead have the same motive of revenge and personality change
- Both shows have similar "aesthetic" and comedic timing (Invisible is a more serious show)
-Spec is more of a Human vs Mutant while Invisible is the usual Police vs Criminal drama

It's very similar. The major difference that Tenshi to Akuma is a "Buddy Cop" show with slight comedy and there's no shifting between past and the present days. While Cold Case is a much serious and darker show.

-Eccentric male lead
-Buddy cop
-Set in an "outcast" police division
-Black comedy
-Both are episodic

Both are adaptation of Ikedo Jun's story about Idealistic Banker who wants to "reform" the bank. The main difference is that Hanzawa Naoki is a suspense and have a big plot while Hanazaki Mai is a episodic drama with slight comedy.

-Mystery solving duo with an opposite personalities
-Have the same "cozy" vibe (Grading, Score, and Cinematography)
-Episodic and fast-paced drama

-Both are Tsutsumi Yukihiko works. Expect a lot of slapsticks, 60's-90's pop culture reference, amazing score, and unique cinematography.
-Yamegoku is basically Keizoku/SPEC, but without the element of weirdness.
-Both drama feature Kitamura Kazuki as a cop dressed and act like a Yakuza.

Have a lot of similarity, mainly in deceiving the bad guys. the difference is that Confidence Man is episodic while Shichinin no Hisho have a main storyline. Nana Ri no Hisho is also a more serious show,

- Credit hogging detective
- Younger female lead
- Both drama elaborate comedy and investigation. Yabe Kenzo is more/less have a gintama-style comedy (Inside jokes, parody, refference) while Nemesis is the usual cheesy Japanese comedy.

Both feature inside jokes, a lot of reference, parody, and over the top comedy. Pick Gintama if you love action or Yabe Kenzo if you like mystery.

*also applies for the future installment.

Have a similar formula.

The difference is that Ninkyo Helper take place in a nursing home while Yoiko no Mikata take place in a Kindergarten.

-Have an eccentric lead
-Both series have a character that specialize in almost everything
-Both series feature a senior that always suppress their junior (in a funny way)
