Case Closed: The Fist of Blue Sapphire, known as Detective Conan: The Fist of Blue Sapphire (名探偵コナン 紺青の拳（フィスト）, Meitantei Konan: Konjō no Fisuto) in Japan, is a 2019 Japanese animated mystery film. It is the twenty-third installment of the Case Closed film series based on the manga series of the same name by Gosho Aoyama, following the 2018 film Case Closed: Zero the Enforcer. The film was released on 12 April 2019.^[8]

This was the last Heisei-era Case Closed film, released weeks before the 2019 Japanese imperial transition.^[9][10] The setting of the film takes place in Singapore, most notably surrounding the Marina Bay Sands.

The film was the 4nd highest-grossing Case Closed films in Japan with mixed to positive reviews. Critics praised its visual effects, direction, and characters but criticized its plot and screenplay. It was the second highest-grossing Case Closed film with a worldwide box-office gross of $123 million.

The world's largest blue sapphire, the 'Blue Sapphire Fist', is said to have sunk when a pirate ship sank in the late 19th century off the coast of Singapore. A local millionaire plots to recover it, and when it reappears at a Singaporean hotel exhibit, a murder takes place and a calling card of Kaitō Kid is found at the scene.

Still in Singapore, Makoto was in the midst of participating in a martial arts tournament where he is joined by Ran and Sonoko to encourage him. Conan is stuck in Japan as he does not possess a passport. However, Kaitō Kid wants to use him to get the sapphire and kidnaps him to take him to the city-state. There, Conan must obey him if he wants to return to Japan; he has his glasses, wristwatch and clothes confiscated, among other things, and must conceal his real identity.

Ran, who does not recognize him, asks him his name and Conan improvises the name of "Arthur Hirai". Disguised as Shinichi Kudo, Kaitō Kid finally manages to get information about the sapphire that is kept in the underground vault of a mansion. During his intrusion into the premises, he is trapped and comes face to face with Makoto.

Leon Lowe, a detective and behavioural psychologist from Singapore, is also searching for the legendary secret treasure buried in the seabed and is in rivalry with Conan and Kid.
