Yakuza: Like A Dragon is filled with shout-outs to the Dragon Quest franchise, and it managed to include one of the longest-running references in the series by swapping out a corpse for a drunk.
The mainline Yakuza games are action-adventure/open-world games, with visual elements that are straight of the classic Sega arcade line-up. The most recent game in the series is Yakuza: Like A Dragon, which uses turn-based commands for its battle system. The in-universe reason for this change is that protagonist Ichiban Kasuga is a huge fan of the Dragon Quest series and sees everything in JRPG terms.
There are lots of references to the Dragon Quest series in Yakuza: Like A Dragon, but some of them are easy to miss, as they are linked to optional NPCs. If you travel to Isezaki Road, you will see a guy lying down on the ground.
If Kasuga interacts with the guy, he will say this.
This comment is a reference to a long-running event that happens in the Dragon Quest series. If you interact with a dead body, then the game will say something along the lines of "There is no response, it's just a corpse". The exact wording depends on the translation. The mainline Dragon Quest games (including the remakes and most of the spin-offs) have included this line in some capacity. The text usually appears when the main character interacts with a skeleton they find in a dungeon or prison, but there are a few instances when the game subverts the reference, such as people not responding because they're listening too intently to a song.
A number of characters die in gruesome ways in Yakuza: Like A Dragon, and the game could have included the reference in its original form. A lot of the turn-based JRPG elements are treated in a comedic way, with the Dragon Quest references often lamp-shaded by the party members. Yakuza: Like A Dragon directly references things like "an enemy draws near", but it decided to be a bit more light-hearted with the silent corpses.
