Karaoke isn’t the only rhythm game on the Yakuza to separate Like a Dragon: Ishin, since Ryoma can also participate in the Buyo dance. However, it is not immediately available. Only after he arrives in Kyo and you start exploring the northern quarter of town and complete a side story called “Nichibuza’s Newest Fan” can you start “taking classes” and play.
I ended up meeting “Nichibuza’s Newest Fan” and unlocking Buyo’s dance rhythm mini-game in Like a Dragon: Ishin in chapter four. You want to head northeast of Rakunai, right in the Kawaramachi area. You will come across a man trying to steal money from Maijo, the studio teacher. By defeating the thug, she will insist that Ryoma attend a class.
This starts the rhythm game. which involves pressing the directional and action buttons in time with the on-screen indicators to perform. After the first chance, Maijo will tell you that you can now pay to take classes there, which grants you 250 Virtue and permanent access to the activity. You can then return to the venue at any time and pay money to take a class and dance Buyo at Like a Dragon: Ishin.
Like a Dragon: Ishin is available on PS4, PS5, Xbox One, Xbox Series X and PC.
