Despite Haruka Sawamura being the only Yakuza playable protagonist who never fights (with her fight sections being replaced by dance battles) and showing no prowess in martial arts, a trailer for Yakuza Online shows her beating generic enemies on a street alongside the other protagonists of the series.

In a 2020 interview with the YouTube channel Archipel, series producer Toshihiro Nagoshi claimed that the decision to change Yakuza: Like a Dragon from an action game to a turn-based RPG came from a 2019 April Fools' Day video for Yakuza Online showing turn-based combat which was received positively by fans. However, fans and news outlets seemed to take this statement seriously, and Ryu Ga Gotoku Studio's head Masayoshi Yokoyama later had to clarify that it was a joke. The decision to shift to turn-based combat was made before production on the game even began due to it being too drastic of a change to make late into development.
