While driving to a crime family meeting in Yokohama, the wealthy criminal Hideshi Miwa notices another vehicle with a Kyoto license plate following him and has security at his house beefed up by his man Kono. The host calls the meeting to order and first hears from the Kanto Block. The woman running the block, Hisako, says that things are set up so that the newspapers and TV stations will be on top of the matter of corruption within the Ministry of International Trade and Industry when the time is right. The host then calls upon Omaeda of the Osaka-Kobe block to speak. After that Hideshi explains that profits are 10% less than in the previous year but he is expecting counterfeit money from the Philippines, which will mean a total of 360 billion yen for the family. Finally, Omaeda announces that the secret code word name of the organization, "Japan Mafia", has been leaked to the outside. Hideshi explains that there is either a traitor in their midst or else someone from another group deliberately leaked the code word from negotiations. After the meeting, Hisako shows Hideshi a photo of the killer with the scar that the Mutsumi Group is distributing around Tokyo. Hideshi recognizes the killer as his younger brother Takeshi but feels that Iwaida needed to die. Hideshi asks if the boss asked for his younger brother to killer Iwaida and Hisako admits that he did because Iwaida was a thorn in the side of the crime family. Even though they could crush the Mutsumi Group, the boss wishes to avoid an all-out war so Hisako asks Hideshi to find his brother before the killer goes into hiding. She also asks if he would like to have sex with her but he merely leaves. Hideshi's younger brother Takashi is also an underboss in the crime family. He and Hideshi visit their mother at a care home but she is suffering from Alzheimer's and claims not to know anyone named Takeshi. The nurses recall that Takeshi visited earlier in the month, the day before the murder of Iwaida, and that he would not be able to come back for a while so he made arrangements to have money sent to her but did not leave any address. Hideshi and Takashi split up, with Hideshi searching Kyoto and Takashi combing Kobe and Osaka. At the police station Detective Kakuta questions the nurse Rie Ishibashi. She denies that the man in the photograph is the killer, claiming that the killer did not have any scar on his cheek.
