The Danza: The models in the Gandhara videos appear as characters in the side stories using their real first names. Also a case of Identical Stranger as said characters are mostly everyday people (e.g. college student, crosswords buff, convenience store cashier, game center staff) who happen to look exactly like AV idols of the same name, which is lampshaded in the sidestory "The Girl in The Video".
Newbie Boom: Clearly the largest in the west for the series, due to the game being a prequel that doesn't require knowledge of the previous games or characters. The game was sold out in the UK upon release due to short supply. In America, recognizing new players wanted to revisit the previous games, Sega of America ordered a limited reprint of the first four games that could be ordered online (including the rare PS2 games). The "Yakuza Experience" website was also launched to bring players up to speed with the entire series. Each game since has been localized overseas, showing that Sega clearly has faith in the series outside Japan once more. Yakuza 0 has also become a "Playstation Hits" title, a first for the series outside Japan. The release on Steam further cemented this, being the first game in the series that PC-only gamers are able to play.
Reina is voiced by the late Hiromi Tsuru, as her previous actress Junko Mihara had gone into politics. The role would get darrin'd again to Atsuko Tanaka in Kiwami.
Masaru Sera is voiced by Toru Okawa, replacing Ryuji Mizuki.
Pre-Order Bonus: For the localized release, pre-orders of the game were automatically upgraded to The Business launch edition. It included a stainless steel business card holder decorated with Kiryus and Majimas tattoo designs, business cards of Kiryus and Majimas businesses, and a card of the Sunshine Club hostesses.
Prop Recycling: A few rooms are recycled for different substories, such as the Maguro Enterprises office in The Tax Lady also being the hideout for some Jinsei family goons in A Shining Example, and the offices of both Tetsuya the Gigolo and Kinji the Antique Yakuza in Tatsu's debt collection missions.
Role Reprisal: The game sees the return of actors who have been absent from the series for years, although Kazuhiro Nakaya (Nishikiyama) and Shunsuke Sakuya (Kashiwagi) returned previously to voice their characters' expies in the No Export for YouIshin!.
