'100 Days of Deception' Jin Seon-kyu, mistaken for a Japanese actor—a career-defining character

Actor Jin Seon-kyu has captured the living room screen with Japanese acting so natural that even Japanese people are surprised. He, who did not even know Hiragana or Katakana, has completely transformed into Sato Shinichiro, the new Political Affairs Director of the Government-General of Korea. Moving beyond simply handling foreign language lines, he drew admiration from viewers by melting the pronunciation, intonation, and facial expressions into the character. Attention is focused on whether Jin Seon-kyu, who left a strong impression as Wi Seong-rak in the movie 'The Outlaws,' will create yet another career-defining character.

In the recently aired tvN weekend drama '100 Days of Deception,' Jin Seon-kyu took on the role of the Japanese powerful figure Sato Shinichiro, revealing an overwhelming presence from the early stages of the drama. From the scene where he appears at Gyeongseong Station and rapidly exchanges conversations in Japanese with key figures welcoming him, to the scene where he suspects the identity of his counterparts during a meal with Lee Moo-saeng and Kim Hyun-joo, his natural Japanese acting heightened the tension of the drama. In scenes where he brutally massacres village residents without showing any emotional disturbance, he vividly expressed the chilling aspect of a villain.

Sato Shinichiro is a difficult character to act. As a powerful figure during the Japanese colonial period, he must reveal an intimidating presence and hidden ambitions, but if emotions are expressed excessively, the weight of the character may instead become light. Jin Seon-kyu prioritized restrained facial expressions and speech over intense emotional expressions. He built the character's duality by smiling as if he were a good person, while simultaneously pressing his opponents with suspicious glances. As the cruelty hidden behind his friendly face was revealed, the viewers' anxiety grew.

In particular, this performance is drawing even more attention because the lines themselves become a subject of strict evaluation. While action or intense emotional acting can somewhat cover up awkwardness in language, foreign language acting is easy to break immersion if the pronunciation and intonation are even slightly unnatural. Jin Seon-kyu overcame this burden by organically combining Japanese lines with facial expressions. Among viewers immersed in the drama, reactions even emerged saying it was as natural as if an actual Japanese actor were appearing.

Praise from Japanese viewers also drew attention. On videos of Jin Seon-kyu's Japanese acting in the work, Japanese netizens left reactions such as "His Japanese was so good my jaw almost dropped," "I think his pronunciation and intonation are the most natural among the Korean drama actors I have seen so far," and "I really thought he was a Japanese actor I didn't know." Given that foreign language acting is inevitably evaluated more minutely by viewers who use that language, these reactions from local viewers make Jin Seon-kyu's transformation stand out even more.

Behind these results was a fierce preparation process. At a production presentation held last month, Jin Seon-kyu revealed that he lived and trained in Japan to prepare for the Japanese acting. He stated, "I lived in Japan for two months starting this January and memorized only the script for 7 hours every day," adding, "I felt that if I didn't do that, I wouldn't even be able to keep up." He continued, "I also practiced a lot with teachers. I, who didn't even know Hiragana or Katakana, did not let go of my practice and kept doing it." His efforts, starting from the basics of the language to memorizing the script for long hours and undergoing repeated training, resulted in the natural acting seen on screen.

Jin Seon-kyu's preparation did not stop at simply speaking Japanese fluently. This is because he had to convincingly express the mindset, behavior, and attitude toward others as a Japanese powerful figure. In particular, Sato Shinichiro is a character who is loyal to the Japanese ruling power while hiding his own ambitions. Jin Seon-kyu completed the character's threatening atmosphere by imbuing his speech and expressions with the arrogance and ruthlessness of a powerful figure. It is the result of technical training in learning the language and acting concerns in building the character's inner self coming together.

Jin Seon-kyu already has the shadow of a powerful previous work. In the movie 'The Outlaws,' he engraved his name in the public's mind with a unique way of speaking and a strong presence while playing the Korean-Chinese gang member Wi Seong-rak. In this work as well, he is showing another transformation through acting using foreign language and intonation, leading to a natural comparison between the two characters. Jin Seon-kyu has previously stated, "I filmed '100 Days of Deception' with the desire to erase Wi Seong-rak." This is a part where his will to prove himself as a new character without settling for past success is visible.

If Wi Seong-rak remains a representative character in Jin Seon-kyu's acting career, Sato Shinichiro is expected to be an opportunity to prove the actor's capabilities in a completely different way. The difference between the two characters is clear in that, instead of rough speech and explosive energy, he creates tension with restrained language and cold expressions. The fact that an actor who did not even know Hiragana lived in Japan for two months and memorized the script for 7 hours a day, eventually drawing admiration from local viewers, simultaneously shows Jin Seon-kyu's persistent effort and acting transformation.

Will Sato Shinichiro be able to establish itself as another representative work for Jin Seon-kyu beyond Wi Seong-rak? Expectations are gathering for what kind of waves Jin Seon-kyu's acting, which has expanded his limits every time he challenged a new character, will cause in the future. '100 Days of Deception' is broadcast every Saturday and Sunday at 9:10 PM.
