Blue Road on Netflix: November 20 Release Date and Cast

The Blue Road premieres on Netflix on November 20, 2026. Son Suk-ku and Eita Nagayama star as detectives. Set in 2002, this crime thriller series follows an investigation that crosses national borders.

The release schedule is based on Netflix's November 5, 2026 announcement.

Release Schedule and Key Information

The Blue Road is scheduled to premiere on Netflix on November 20. The main poster and trailer were released on November 5 (South Korea). That announcement does not specify the total number of episodes or the release time. The schedule is confirmed in Netflix's main poster and trailer announcement.

The Blue Road Cast and Characters

Son Suk-ku and Eita Nagayama play the two detectives at the center of the joint investigation. Kim Shin-rok, Choi Sung-eun, and Jung Jae-young also appear in key roles. The roles below are based on the descriptions in Netflix's November 5 announcement.

Spoiler-Free Synopsis

The story centers on a joint investigation by a Korean detective and a Japanese detective. A series of murders spanning national borders sets the investigation in motion. The two detectives follow mysterious messages left at the crime scenes. Netflix's title description classifies the series as a thriller featuring a police duo.

The 2002 setting is also a basic part of the story. The main poster includes a scene of fans cheering during the Korea-Japan World Cup. Netflix described this in its poster announcement.

The Original Comic and the Working Title

The series is based on a comic of the same name that Kwon Ga-ya and Keishi Edogawa worked on. The Busan International Film Festival's program notes explain this connection to the source material. Cho Yu-jin and Han Jun-hee adapted the comic for the series. The details appear on the Busan International Film Festival title page.

The working title was "Road" when production was announced. Netflix announced production under that title on September 12, 2025. Later official release announcements used the title "The Blue Road." Early production information is available in the Road production announcement.

What to Watch For

The way the two detectives work together is a key point of interest. The production announcement explained that the adaptation would take the original story in a different direction. It is therefore difficult to assume that the comic and the series will follow the same course. The following are aspects to watch for based on the production announcement and festival introduction.

• How Kim Seok and Inose treat each other during the joint investigation.
• The relationship between the two detectives that emerges as they investigate the case.
• The adaptation and direction that bring the comic's story to the screen.

How to Watch and How Festival Screenings Differ

Netflix is the online viewing platform. The series was presented in the Busan International Film Festival's "On Screen" section. The festival schedule is separate from the Netflix release schedule. Its invitation to the festival is stated in Netflix's festival announcement.

The individual festival screening dates are recorded on the official title page. Streaming information is available on the Netflix title page. The rating on the Korean title page is adults only.

Festival Runtime and Total Episode Information

The 130-minute runtime listed by the Busan International Film Festival refers to the festival screening. This figure cannot be used to calculate the total runtime on Netflix. It does not indicate the total number of episodes, either. It is important to distinguish which release format the figure refers to.

These distinctions are based on the festival title information. The release date alone also does not establish that all episodes will be released at once. The release format must be confirmed through further announcements from Netflix.
