Meet the Duty First Kiss Later Cast
The success of this adaptation rests heavily on the shoulders of its main duo. The production team chose two actors who perfectly embody the contrast between an old school detective and a modern, high flying officer.
Shu Watanabe as Heisuke Takoi
Shu Watanabe brings a grounded, comforting energy to the role of Heisuke Takoi. Takoi is a non career officer in his forties who works in the Criminal Affairs Division. Unlike the stereotypical hard boiled detective, he is deeply loved by his local community for his kind nature. Watanabe, a veteran of the industry known for his versatility, portrays Takoi’s struggle with his unexpected feelings for a younger man with both humor and sincerity.
Ryu Saito as Shiono Shu
Ryu Saito takes on the role of Shiono Shu, the sharp tongued and ambitious junior officer. Shiono is in his twenties and belongs to the Community Safety Division. As a career track officer, he is the polar opposite of Takoi. Saito captures the icy exterior of a man who is focused solely on his professional trajectory, only to have his world upended by the warmth of his senior colleague.
Supporting Characters
- Haruka Kudo as Mariko Egawa: A vital presence at the station who often observes the tension between the two leads.
- Yuta Kanai as Jiro Hasegawa: Another member of the Yamanomichi team who adds depth to the workplace dynamic.
- Doronzu Ishimoto as Tamotsu Yagi: Providing veteran support within the police force.
- Rei Kikukawa as Matsuyuki Misuzu: A key figure who influences the narrative as it progresses toward the finale.
Plot Summary: A Collision of Hearts and Duties
The story of Duty First, Kiss Later begins at the peaceful, semi rural Yamanomichi Police Station. Heisuke Takoi is content with his life as a bachelor, spending his days serving the local citizens. His peace is constantly disrupted by Shiono Shu, his younger neighbor in the police dormitory and his most frequent professional rival. The two men clash over investigative methods, office politics, and even their personal living habits.
Everything changes when Takoi’s well meaning peers set him up on a marriage meeting. This catalyst forces Shiono to confront his own hidden feelings, leading to a series of events that blur the lines between their professional duties and their private desires. The series explores themes of career pressure, the isolation of small town policing, and the courage it takes to pursue love when it defies societal expectations.

Where to Watch Duty First Kiss Later Online
Finding legal ways to stream Japanese miniseries can sometimes be a challenge for international viewers. However, Duty First, Kiss Later has seen a wider distribution thanks to the global interest in Japanese BL.
Currently, the series is available on specialized Asian drama platforms. Viewers should check GagaOOLala and Rakuten Viki, as these services frequently host high quality J-Drama content with English, Spanish, and Portuguese subtitles.

Comparison: Manga vs Live Action Adaptation
Adapting a web manga is always a delicate process. The original work by Su is known for its expressive art and the subtle ways the characters show affection. The live action version succeeds by leaning into the physical comedy of the police dormitory setting. While the manga focuses heavily on Takoi’s internal monologue, the TV series uses the chemistry between Shu Watanabe and Ryu Saito to convey the growing attraction through glances and body language.
One of the most praised aspects of the live action version is the expansion of the supporting cast. In the manga, the other officers are often background noise, but in the drama, characters like Mariko Egawa feel like essential parts of the Yamanomichi community. This adds a layer of realism to the show, making it feel less like a standard romance and more like a true workplace drama.
Duty First, Kiss Later stands out as a highlight of the 2026 drama season. By casting seasoned actors like Shu Watanabe alongside rising stars like Ryu Saito, the production team created a world that feels both grounded and aspirational. If you enjoy stories about enemies becoming lovers, the quirks of small town life, or the complexities of the Japanese police system, this is a must watch series.
Now that the series has concluded, it is the perfect time to start a binge watch. Head over to your favorite streaming platform and experience the charm of Yamanomichi for yourself. Don’t forget to follow the official social media tags for potential news on future specials or cast interviews.
