YAKUZA 4

Available mini-games are pachinko, fishing, onsen, table tennis, hanafuda and karaoke, including duets with non-player characters (NPCs). In Haruka's Wish, the player must raise Haruka's trust level. Each main character has a side game or goal which must be completed, and many side games are related to trophies.

Akiyama may create friendship (馴染み Najimi) with some NPCs by buying them items, or with some storekeepers by being a regular customer. His other mission, Create a #1 Hostess! (No.1キャバ嬢をつくろう！ No.1 Kyabajō o Tsukurō!), is to scout girls for the cabaret he owns. A girl is improved by dressing her up and training her. After she becomes number one, the player can choose a final outfit for her and she will appear at the cabaret. A similar challenge in the Japanese version of Yakuza 3 was cut from overseas versions.

Saejima's mission, Create a Fighter! (格闘家をつくろう！ Kakutōka o Tsukurō!) is to train fighters to win tournaments after 50 rounds or less of training (building up movesets). Different movesets allow different moves to be performed.

Tanimura's mission, Resolving Police-Radio Disputes (警察無線トラブル解決バトル Keisatsu Musen Toraburu Kaiketsu Batoru), is to keep the peace on the streets of Kamurocho. Radio reports tell him where to find incident, and the player must defeat the perpetrator. In Kiryu's mission, Team Encounter Battle (チームエンカウントバトル), seven gangs attack him and he must fight to reach each gang leader. Each character has his own style of fighting and special moves.[10]
