I would like to ask about the name of this Japanese drama. Thank you.

It is the popular Japanese drama "The Winner Is Justice" from Fuji TV. Since its broadcast in April 2012, it has received praise from countless audiences and even won many awards such as the Tokyo Japan Drama Awards Series Excellence Award. Masato Sakai's "venomous tongue" as the leading actor is cherished by countless fans.

Summary

The rookie Mako (played by Aragaki Yui) of Miki Law Firm, under the guidance of the president’s secretary Sawachi (played by Koike Eiko), found the legendary lawyer Koumemon Nosuke (played by Masato Sakai), to help the parties involved in a murder case to clear their names. Gu Meimen's defensive ability is very high, and he will do whatever it takes to win. So far, he has maintained an impressive winning record. He was once the protege of Miki (Katsuhisa Ikase). But the incident caused a break between the two giants in the legal profession. In order to pay huge legal fees, Gu Meimen agreed to go out. He won the lawsuit with his eloquent ability to confuse right and wrong. Afterwards, Dai joined Gu Meimen's firm to continue her law practice, and a series of subsequent lawsuits brought the old grievances between Gu Meimen and Miki back to the surface.

This is also a battle between law and justice...
