Justin Chien age has become a popular search since the actor won attention for playing Charles Sun in Netflix’s The Brothers Sun. According to several current entertainment listings, Justin Chien was born on January 4, 1998, which would make him 28 years old in 2026. However, some websites report a different birth year, so his exact birth date has not been reported consistently across every public source.

What Is Justin Chien Age in 2026?
Justin Chien is widely listed as 28 years old in 2026.
Sources including TV Insider and Plex list his birth date as January 4, 1998. Based on that date, he turned 28 on January 4, 2026.
There is an important point to understand, however.
Not every website agrees about his date of birth. Famous Birthdays, for example, currently lists January 4, 1996, which would make him 30 years old in 2026. Because of that difference, readers may see different answers when searching for Justin Chien’s age online.
The 1998 birth year appears across several current entertainment listings, so 28 is the age most reasonably supported by those sources as of 2026.
When Is Justin Chien’s Birthday?
Justin Chien’s birthday is commonly reported as January 4.
If the widely reported January 4, 1998 date is correct, his zodiac sign is Capricorn.
He would have celebrated his 28th birthday on January 4, 2026.
Again, because publicly available websites do not all agree on his birth year, it is better to describe January 4, 1998 as his commonly reported birth date instead of treating it as an undisputed fact.
Who Is Justin Chien?
Justin Chien is an actor who became widely recognized after appearing as Charles “Chairleg” Sun in the Netflix action-comedy drama The Brothers Sun.
The series follows a powerful Taiwanese crime family whose lives become dangerous after an attack on the head of the family.
Charles travels from Taipei to Los Angeles to protect his mother and younger brother.
Netflix describes Charles as the older son of a crime boss who was raised to become a tough criminal. Justin brought both action and emotion to the character, helping Charles become one of the show’s most memorable figures.
The series also starred Oscar-winning actress Michelle Yeoh as Eileen “Mama” Sun and Sam Song Li as Bruce Sun.
Netflix released the eight-episode series in 2024.
Where Was Justin Chien Born?
Current profiles commonly report that Justin Chien was born in Taipei, Taiwan.
A biographical entry about him also says that he was born in Taiwan and grew up in Hong Kong.
This international background fits naturally with many of the stories and characters that later became part of his acting career.
His rise has also helped bring more attention to Asian and Asian-American actors working in major Hollywood productions.
Justin Chien Studied Acting at USC
Justin Chien did not simply walk onto a television set and become famous overnight.
He studied acting seriously.
The University of Southern California School of Dramatic Arts confirms that he earned a BFA in Acting in 2018.
USC has continued to feature Chien after his graduation.
In March 2024, he returned to the university for a fight workshop with students. The event focused on stage fighting and the way physical action can help tell a story.
That is especially interesting because action became an important part of his performance in The Brothers Sun.
USC also reported that Chien had gone through the difficult experience many young actors face after leaving university.
Before landing his major television role, he spent years working, auditioning and developing his skills.
His story is therefore not only about becoming famous. It is also about training and staying patient while trying to build a career.
Justin Chien in The Brothers Sun
For many viewers, The Brothers Sun was their first introduction to Justin Chien.
He played Charles Sun, the dangerous but complicated older brother at the center of the story.
Charles knows how to fight and protect his family, but he also wants things that his violent life makes difficult to enjoy.
Netflix described the character as someone who dreams of simple things such as peace, happiness and love.
That emotional side made the character more than just an action hero.
Chien had to show Charles as both strong and vulnerable.
The role also gave him the chance to use his martial arts background.
Netflix has noted that Chien has experience in Muay Thai and jiujitsu, skills that were useful for the show’s many action scenes.
His Martial Arts Background
Justin Chien’s ability in action scenes did not come only from acting tricks.
He has real martial arts experience.
His training includes Muay Thai and jiujitsu, according to Netflix.
This background helped make his fight scenes in The Brothers Sun look more natural.
During his 2024 visit to USC, Chien also helped students learn about fight choreography and how a good action scene should help tell the story rather than exist only for excitement.
That combination of acting and physical skill may continue to open doors for him in action films and television shows.
Justin Chien’s Career Before The Brothers Sun
Although The Brothers Sun became his breakthrough project, Chien had already been working before the Netflix series arrived.
Netflix’s original casting announcement mentioned his earlier appearance in Two Sides: Unfaithful and the Disney Television Discovers Talent Showcase.
He also appeared in smaller film projects while developing his career.
One of his earlier stage credits came shortly after university.
In 2018, USC announced that Chien had joined the cast of Valley of the Heart at the Mark Taper Forum, where he played Joe “Yoshi” Yamaguchi.
These smaller opportunities helped him gain experience before his larger television breakthrough.
Justin Chien in The Season
Justin Chien has continued building his career after The Brothers Sun.
In 2026, audiences could also see him in The Season, where he plays David Ho.
Disney+ lists Chien among the show’s main cast alongside Jessie Mei Li, Toby Stephens, Chris Pang, Kōki and Celina Jade.
The series is set around the wealthy social world of Hong Kong and mixes drama, secrets, betrayal and revenge.
It premiered in 2026 and gave Chien another major role after his Netflix breakthrough.
His part in the show also reflects the growing international direction of his acting career.
Justin Chien Is Also Joining Avatar: The Last Airbender
Another exciting project for Justin Chien is Netflix’s live-action Avatar: The Last Airbender.
Netflix has announced Chien as King Kuei, the sheltered ruler of Ba Sing Se.
This role gives Chien a chance to join another large international Netflix production.
For fans who discovered him through Charles Sun, seeing him play King Kuei will show a different side of his acting ability.
Charles is a highly trained fighter living in a violent crime world.
King Kuei is a ruler who has lived a much more protected life.
That difference could help Chien avoid being known for only one type of character.
Why Are People Searching for Justin Chien Age?
Interest in Justin Chien’s age increased as more viewers discovered him through The Brothers Sun.
When an actor suddenly becomes popular, fans naturally want to know more about the person behind the character.
People begin searching questions such as:
“How old is Justin Chien?”
“When is Justin Chien’s birthday?”
“Where was Justin Chien born?”
“What other movies has Justin Chien been in?”
The fact that Chien looks convincing as a powerful and experienced character can also make viewers curious about his real age.
With his career continuing through projects such as The Season and Avatar: The Last Airbender, interest in his personal and professional background is likely to remain strong.
Is Justin Chien Taiwanese?
Justin Chien is widely described as having strong Taiwanese roots.
Current biographical sources report that he was born in Taiwan, while The Brothers Sun also connected him closely with a story centered on a Taiwanese family.
His background became particularly meaningful in a show where Taipei, Taiwanese culture and family relationships played important roles.
The series also featured a largely Asian cast and explored family identity alongside its crime and action story.
Why Justin Chien’s Career Stands Out
Justin Chien has several qualities that help him stand out.
First, he has formal acting training from USC.
Second, he has martial arts skills that allow him to handle physical roles.
Third, he has shown that he can combine action with emotional acting.
Finally, his recent projects show that he is moving into very different kinds of roles.
Charles Sun in The Brothers Sun, David Ho in The Season, and King Kuei in Avatar: The Last Airbender are not the same kind of character.
That variety could be important as his career develops.
Final Thoughts
The question of Justin Chien age has a simple answer with one small warning.
Several current entertainment sources list Justin Chien’s birth date as January 4, 1998, which makes him 28 years old in 2026. However, another widely used celebrity database reports 1996, so there is still some disagreement online about his exact birth year.
What is much clearer is that Chien’s career is growing.
After studying acting at USC, he worked through smaller roles before becoming widely known as Charles Sun in The Brothers Sun. He has since continued appearing in major projects, including The Season and Netflix’s Avatar: The Last Airbender.
At a relatively young age, he has already built a career that combines drama, action and martial arts.
