Sujimon Sensei describes Hawaii as being "blessed by the sun and the moon." Considering that Sujimon Sensei and several other related elements introduced in Yakuza: Like a Dragon are parodies of the Pokémon series, this line is most likely a reference to Pokémon Sun & Moon, which takes place in a region inspired by Hawaii.

While it’s widely believed Like A Dragon: Infinite Wealth is the first game in the Like A Dragon series to feature a portion set in the United States, there was actually a cutscene at the beginning of Kurohyo 2: Ryu ga Gotoku Ashura-hen set in Las Vegas, Nevada.

The virtual YouTuber KSon voices the character Kei in both the English and Japanese dubs of Like a Dragon: Infinite Wealth. KSon noted that while she found it easier to voice act in Japanese, the staff in the studio praised her pronunciation during voice recording.

Two of Kiryu’s Bucket List memories in Like a Dragon: Infinite Wealth with the shared title "Dreams of a Past Life" have Kiryu reminisce on dreams he had where he was the historical figures Miyamoto Musashi and Sakamoto Ryoma. This references two games thought to be non-canonical spin-offs: Ryuu ga Gotoku Kenzan! and Like a Dragon: Ishin!, and suggests them to have actually been Kiryu’s dreams the whole time. This is also notable as Ryuu ga Gotoku Kenzan! has yet to receive an English release.

The character Andre Richardson from Yakuza 3 is notorious for speaking in poor English despite him being American, with one line especially where he says:


In saying the line, "roof" is pronounced more as "ruff". This meme was referenced with his return in Like a Dragon: Infinite Wealth, where in the English dub, after Ichiban spends a night at the bar he runs, he says the line:


And during this line he says the word roof in a similar matter.
