Promotion and release Following a tease in August 2025, Fallen Angel of the Highway was revealed to be the 29th Detective Conan feature film on December 2, 2025.

The film was released in Japan on April 10, 2026.

Reception

Box office The film has earned over ¥13 billion ($81 million USD), making it the highest-grossing among 2026 releases in Japan. It has now reached 27th place in the all-time domestic box office rankings, and ranks 4th among Detective Conan films, behind Detective Conan: Black Iron Submarine, Detective Conan: One-eyed Flashback and Detective Conan: The Million-dollar Pentagram.

Critical reception Phil Hoad of The Guardian gave the film 3/5 stars and says, "With a torn-from-the-headlines conspiracy revolving around automated vehicles and big data, Fallen Angel of the Highway thrashes through the gears of another briskly enjoyable whodunnit."

The film received a 3.5-star rating from Robert Ewing of The People's Movies, who says "[its] ambition is a double-edged sword, leading to some of the most thrilling moments in the franchise but lacking the necessary bite to be one of the best."
