Yakuza/Yakuza Kiwami
During their search for Mizuki, Date tells Kiryu a body that resembles hers was found in Tokyo Bay. Kiryu sees the tattoo on her chest and recognizes it as Utabori's work. They both go to Ryujin Hall to talk to him. While there, Kiryu receives a call from Nishiki telling him he wants to meet at Serena tomorrow. Utabori then offers to touch-up Kiryu's back, sensing that a dangerous battle is in Kiryu's future. Date and Kiryu then leave to prepare for Kiryu's meeting with Nishiki.
Yakuza 3
During the substory "Dotting the Eye", in Chapter 6, Kiryu brings Rikiya to Ryujin Hall to have his tattoo finished by Utabori, as Rikiya's original tattoo artist passed away sometime before being able to complete it.
