Japanese Task Force

The Task Force (捜査本部, Sousa Honbu), later called the Japanese Task Force, is the primary organization searching for Kira.

Overview
The Task Force is created by Ryuzaki after he deduces that Kira is in Japan and is the only organization within the country that is searching for Kira. The existence of the organization is not made public, and the names and personal information of all of the members are kept secret. After Ryuzaki's death, Light Yagami heads the organization and begins operating under the title of L.

The NPA initially had many members assigned the Kira case. As Light becomes more ruthless in his actions, however, it becomes clear that anyone searching for Kira would be in great danger, and the officers are given the choice to stay or leave without risk of losing their job or paycheck. They are told to make the choice carefully and to take their family into consideration.

Nearly every member decides to leave the case. The members left are addressed by Ryuzaki as L via computer, who says that he will meet them face-to-face. Ryuzaki had, in fact, been waiting for the other members to leave, knowing that those who stayed would be truly dedicated to the investigation.

Film series
In the first two films, Death Note and Death Note: The Last Name, the Task Force is essentially the same as in canon. A new female member, Sanami, is added to the team.

After the Kira case is resolved, the Task Force remains active and continues to search for Death Note-related murder.

Ten years after the Kira case, Matsuda is the only remaining member from the original team. New members include Tsukuru Mishima, Sho Nanase, Shin Kuromoto, Uei Uragami, and Captain Junrou Sugawara. All members of the Task Force continue to use aliases, except for Matsuda and Sugawara. Getting onto the team includes passing a polygraph test.

In the Death Note: New Generation episode Mishima's Chapter: Rebirth, the new Kira reveals themself directly to the Task Force by controlling a criminal. Afterword, the Task Force is renamed the Death Note Countermeasure Task Force, and they ask the new L, Ryuzaki, to assist with the case. Ryuzaki initially declines, but in the second episode, Ryuzaki's Chapter: Dying Wish, Ryuzaki agrees.

In Death Note: Light Up the NEW World, the Task Force with Ryuzaki search for the six Death Notes.

Musical
In Death Note: The Musical, the Task Force is formed prior to L's involvement. The only members named in the production are Soichiro Yagami and Kanzo Mogi. According to the Korean production credits and the lyrics for Change the World, the additional members are Ide, Matsuda, Aizawa, and Ukita. Light does not join the Task Force in the musical.

The Task Force sings just one song: Change the World Reprise. After the FBI agents are killed, Soichiro gives the members the option to resign. The Task Force members sing about their obligations to their families, and some of them hope that their families will understand their decisions to risk their lives. At the end of the song, Ide resigns.

After the death of the FBI agents, L has Mogi follow Light. When Light and Misa meet for the first time, Light asks Misa to give him the man's name. Misa is reluctant to do so because he isn't a criminal, but she ends up doing so. Light kills Mogi using the Death Note; Mogi steps out in front of a bus and dies.

The Task Force observes Misa's confinement with L.

Unlike in canon, the Task Force is not present for the final showdown where Light is revealed to be Kira.
