Unification of Japan Gaiden: Yamazaki Ichimon 3 (2022)

A man caught poaching off the Sanriku coast is detained by Ueki (Daisuke Nagakura). He claims to be the childhood friend of Joji Sakaguchi (Takashi Kitadai), prompting Joji to head to Ishinomaki with Ishizawa (Hiroto Honda) and Yamamura (Kenta Kawasaki). The man is confirmed to be Kazuki Yabushita (Naoki Tanaka), now a yakuza in Ibaraki, secretly poaching abalone with his diver wife Akiko (Michiko Tanaka) for drug deals with the Chinese mafia. When Akiko—also Joji’s former girlfriend—is found after going missing, tensions erupt. After Kazuki assaults Akiko over a failed deal, the Yamazaki faction intervenes, but in the chaos, Kazuki and Akiko are abducted by his senior Hyodo (Yasuyuki Hamatani). Can they be rescued in time?
