Jason Remar has worked on American television, appeared in Japanese action cinema and performed in stage adaptations of major entertainment franchises. Known professionally as Jay, he is also the son of Hollywood actor James Remar, whose work includes The Warriors and Dexter. Yet the younger Remar’s career is more international than that connection alone suggests.
His credits include the American film Gun, the television comedy Wilfred, the revived Magnum P.I. and Japan’s High & Low films. He has also appeared in theatrical productions connected to Fate/Grand Order and The New Prince of Tennis. Together, they establish a career across languages, formats and entertainment industries.

Why Jason Remar Is Known as Jay
The actor uses both Jason Remar and Jay in professional credits. American screen credits use his full name; Japanese productions often use JAY.
That distinction can obscure the connection between his American and Japanese credits.
Japanese entertainment records place his birth in the United States on 4 November 1989. He was therefore 36 years old in October 2026. His Japanese stage biography also identifies James Remar as his father.
His casting biography describes him as fluent in English and Japanese and based between New York City and Tokyo.
A Hollywood Beginning Shared With James Remar
Gun Brought Father and Son Into the Same Film
One of his earliest documented screen credits came in Gun, the 2010 American crime thriller directed by Jessy Terrero. The film starred Curtis “50 Cent” Jackson and Val Kilmer, alongside an ensemble including Danny Trejo.
Jason played a policeman, while James Remar portrayed Detective Rogers. It remains a documented professional overlap between father and son.
Their roles were different in scale, and Jason’s was a supporting part. Nevertheless, the production gave him a screen credit within an established American cast. It is more accurate to view that appearance as an early acting job than as evidence of an immediate starring breakthrough.
Television Roles in Wilfred and Magnum P.I.
In 2013, Jason appeared as a grocery clerk in Wilfred, the American comedy series starring Elijah Wood. Its surreal comedy offered a contrast with crime drama.
He later played David Greene in a 2019 episode of Magnum P.I., the modern reboot starring Jay Hernandez. The appearance added a network television credit to his film and international theatre work.
His father also appeared in Magnum P.I. as Captain Buck Greene, a separate character.
Neither credit made Jason a series regular.
The Japanese Screen Roles That Expanded His Career
Nakamon in the High & Low Films
Japan’s High & Low franchise combines gang rivalries, stylised action and an ensemble of performers. Its interconnected stories span television, cinema and music-related entertainment.
Jay played Nakamon in High & Low: The Movie 2 – End of Sky, released in 2017. He is identified among the characters associated with Jesse’s prison gang, a group operating within the franchise’s wider network of rival factions.
Japanese film records also credit him as Nakamon in High & Low: The Movie 3 – Final Mission, released later that year. He therefore played the character in two films.
Working in this franchise brought him into a recognisably Japanese form of action storytelling. Its ensemble action format differed from his American television work.
The franchise relies on overlapping storylines rather than following one central character throughout. That context is important when judging a supporting role: Nakamon belongs to an ensemble, not the centre of either film. The credits still mark a meaningful expansion into Japanese cinema.
From Action Films to Japanese Live Theatre
Playing Agravain in Fate/Grand Order
Another important credit arrived with Fate/Grand Order THE STAGE – Divine Realm of the Round Table: Camelot. The production adapted material from the popular Japanese role-playing game and was staged in 2017.
Jay portrayed Agravain, a stern knight associated with King Arthur’s Round Table.
In comments published for the show, he spoke about enjoying Japanese manga and anime from childhood and his excitement at joining a stage adaptation of a familiar fictional world. That personal interest gives useful context to his move into Japanese performance.
Unlike a brief screen appearance, stage work demands sustained performance before a live audience.
The original stage run included July performances and later dates in 2017. Adapting a game meant performing for audiences already familiar with its characters.
The New Prince of Tennis and a Returning Stage Character
In 2023, Jay joined The New Prince of Tennis musical series as A. Frankensteiner, a member of the German team. The character is presented as exceptionally precise and obedient, earning a reputation as a tennis cyborg.
The Third Stage ran in Tokyo and Osaka from October to November 2023, with JAY in the cast.
He also appeared on the cast roster for the franchise’s autumn 2023 sporting event.
These credits make theatre an important part of his documented work. The musical ran at Tokyo Dome City Hall, Osaka’s Mielparque Hall and Tachikawa Stage Garden, placing him within a touring Japanese theatre production rather than a single promotional appearance.
What His Acting and Modelling Background Reveals
Jason describes his professional work as acting and modelling. His casting biography identifies fitness and sports modelling, SAG-AFTRA membership and professional representation alongside acting credits.
The same professional material identifies training or skills in aikido, boxing, archery, swimming and horse riding. It also mentions guitar and ukulele. Such skills are relevant to physically demanding roles.
No major modelling contract or award has been independently verified.
His reported fluency in Japanese and English is especially significant. Bilingual ability supports work across American and Japanese productions.
The Family Connection Behind Public Interest
James Remar, born in Boston in 1953, has built a lengthy screen career. His best-known roles include Ajax in The Warriors, Albert Ganz in 48 Hrs. and Harry Morgan in Dexter. He has also appeared in Sex and the City, Black Lightning and Oppenheimer.
Jason’s mother is Atsuko Remar, who has generally maintained a lower public presence than her husband. James returned to the Dexter franchise in 2025’s Dexter: Resurrection. Jason’s career has taken a different geographical path. Accounts of the family identify another child, Lisa Remar, who has pursued music.
His upbringing and education, however, are not publicly documented in comparable detail.
Although his father’s screen work is far more extensive, Jason’s credits demonstrate a separate route through American television and Japanese entertainment. Their shared credits should not be mistaken for proof of professional influence.
Where His Career Stands Today
The most clearly documented later work concerns The New Prince of Tennis theatre productions and associated professional material. His acting résumé also records earlier Hollywood and Japanese screen appearances.
The available professional credits do not establish a new major film, continuing television role or stage booking for him in 2026. That does not establish retirement.
His publicly identified Instagram handle is jay_kenji_remar. Social posts do not independently confirm contracts or personal milestones.
Details of a spouse, children or romantic relationship are not reliably established. Likewise, an exact net worth, salary and modelling income have not been independently verified. Speculative figures circulated on celebrity websites should not be presented as financial facts.
Conclusion
Jason Remar’s work is best understood as a cross-cultural acting career rather than merely an extension of James Remar’s fame. His documented credits connect American film and television with Japanese action cinema and major stage adaptations. The Japanese theatre roles, in particular, reveal a side of his work that is easily missed when attention stays on his Hollywood family connection.
