Personally, I really like Nine: Nine times Time Travel :D and after watching first episode of Tunnel, I am already addicted to it!~ Those who love time slip dramas will definitely love this too :) (if you aren't too picky) It brings me laughter (natural type of comedy), tears, nervousness etc. while being intense. While Nine:Nine times travel time travel via incenses, Tunnel is via Tunnel as the title mentioned.
Cases were interesting.

Both have Kubozuka Yosuke
Both have this kinda Japanese 90s filming atmosphere
They sometimes give the same feeling, although IwGp is a drama and Go a movie

Both have cool action scenes.
Lupin III was kinda lacking when it came to the plot but it was still pretty enjoyable.
Also the female lead in Joker Game reminded me of the female lead in Lupin II somewhat. However Meisa Kuroki is a better actress than Fukada Kyoko.

Water always is the mystery entity.... for SSL it's time travel and for LotBS is memories. In a sense, they're both time travel and show how love has no time but overall they have the same comedic feeling and "foreigner" trying to get accustomed to life in a new world.

Chief Kim and Modern Farmer, both have a big ensemble cast that you can't help but love each and every character! Their main theme is comedy and there's a lot of it (but they don't have the same kind of humor imo)

Mistaken timetravel, love you didn't know existed and changing the past.

- chairman's son (boss) and lowly employee
- theme of lunchboxes? though in this case, it's being given to the employee rather than boss

Both of these dramas mainly focus on the developing romantic relationship between a boss and an employee at his company.

There are many similar plot points, but in general so I don't spoil anything, both are great romances with an intriguing overarching plot. The male leads are both princes while the female leads are from a different "clan". Ten Miles of Peach Blossom has more fantasy elements, but the development between the leads are similar (they get together early on) . If you love one, you'll definitely love the other!

In both the movies the plot is similar. Here instead the female lead is struck with the tragedy of cancer. The main similarity is at the end both the leads determines to contain that only one love and being in that love.. Try it

Both drama are about revenge. The main girl is abandonned by her boyfriend due to circumstances. Contrary to "Unknown Woman" the boyfriend is not a jerk! But what is important is that the main girl is Lee Yuri! She is so pretty when she takes her revenge!!!

-Awesome heart warming lawyers
-Great subordinate friendship
-Nice cases in both dramas
If u like one u will like the other

THIS STORY IS ANOTHER EPIC TANG HISTORICAL ABOUT EMPRESS WU ZETIAN, LATER KNOWN AS EMPEROR WUZHAO / TIAN HOU. A GREAT PERFORMANCE, EXCELLENT QUALITY SHOW WITH ONE OF THE HIGHEST BUDGET FILM EVER PRODUCED. IF YOU FOLLOW THE WHOLE ANCESTRY OF TANG DYNASTY'S HISTORY, YOU'LL UNDERSTAND WHY AND WHAT WAS SO GRAND AND GREAT OF TANG DYNASTY AMONGST SO MANY DYNASTIES OVER 5,000 YEARS OF CHINA AND BESIDES QIN DYNASTY.

THIS DRAMA'S STORY IS EVEN MORE BEFORE TIME THAN "THE GLORY OF TANG DYNASTY", IT TELLS THE STORY OF EMPEROR WU ZETIAN'S ( OR ALSO WELL KNOW IN THE DRAMA THE EMPRESS OF CHINA / WU ZETIAN / WU MEI NIANG ...etc ) LATE LIFE AFTER HER HUSBAND EMPEROR GAOZONG OR BETTER KNOWN AS LI CHI, AFTER HIS PASSING, ON HOW SHE RULE THE TANG EMPIRE AND AS THE ONLY FEMALE EMPEROR IN CHINA'S HISTORY.

THIS DRAMA SHOWS THE EARLIER PART ABOUT EMPEROR XUANZONG OR BETTER KNOWN AS LI LONGJI ( GRAND EMPEROR OF THIS "THE GLORY OF TANG DYNASTY" 's LI CHU's GRANDPA ).
