Actress Kim Yoo Jung has drawn attention for her dedication to tvN's hit drama 100 Days of Deception, after it was revealed that she spent five months studying Japanese before filming began.
The actress reportedly devoted much of her free time to learning the language, even continuing her lessons through video calls while traveling overseas for work.
In the drama, Kim Yoo Jung plays Lee Ga Gyeong, a character who learned Japanese and English as a means of survival during the Japanese colonial period.
To make her performance believable, Kim Yoo Jung studied Japanese grammar, conversation, and script delivery for approximately five months before filming.
According to the production team, the actress practiced almost every day and paid close attention to pronunciation, tone, and speaking patterns to match her character's background.
The Japanese language coaching team praised her progress, revealing, "Eventually, she reached the point where she could notice even the slightest mistake in her own intonation."
Director Yoo In Sik also expressed his admiration for the cast's preparation.
"From the moment they were cast, the actors enthusiastically prepared for their foreign-language performances. I was surprised because they were already speaking at a high level during the first script reading," he shared.
The director explained that some cast members continued studying foreign languages for more than a year until filming ended, with language instructors checking their pronunciation and dialogue on set.
Kim Yoo Jung was not the only actor who underwent intensive language training.
Park Jin Young, who plays elite interpreter Sato Hideo, also practiced Japanese and English for months, repeatedly writing and memorizing his Japanese lines.
Meanwhile, Jin Sun Kyu reportedly spent approximately two months in Japan, studying his scripts for seven hours a day despite having no previous knowledge of Japanese.
Their efforts come as 100 Days of Deception continues to gain attention for its performances and storytelling.
According to Nielsen Korea, the drama's sixth episode, aired on October 25, recorded its highest ratings yet, averaging 9.9% and peaking at 10.7% in the Seoul metropolitan area among paid television platforms.
The series also ranked No. 1 on Good Data Corporation's FUNdex TV-OTT drama buzz rankings for the fourth week of October.
Kim Yoo Jung placed No. 2 in the performer buzz rankings, while Park Jin Young followed at No. 3, with both maintaining their positions for two consecutive weeks.
With the drama gaining momentum, Kim Yoo Jung's five months of Japanese lessons have highlighted the preparation behind her performance.
100 Days of Deception will air its seventh episode on October 31 at 9:10 PM KST on tvN.
