The film topped the Japanese box office its opening weekend, beating the popular film Your Name. (Kimi no Na wa.) which had held the top for nine consecutive weeks. Within a month of opening, the film earned over 2 billion yen (about US$17.85 million) and had sold over 1.5 million tickets.
It averaged 2.8 out of 5 stars on Eiga.com, 2.73 out of 5 stars on Yahoo, and 6.5 out of ten stars on IMDB. The main criticism of the film was that it was not as clever as the previous ones with little reminiscent of the intellectual games that were played between L and Light. Misa's role was generally praised, as were the CGI of the shinigami.
The film was released on DVD and Blu-ray in Japan on April 19, 2017. Four versions were available: the standard film on DVD or on Blu-ray, and the Complete Set version on DVD or Blu-Ray. All versions include the film with Japanese subtitles.
The Complete Set, for both Blu-ray and DVD, has three discs total with extra features on the two additional discs:
