In short, it offers up "some performance improvements". Yeah, that's it! We're not sure exactly what kind of improvements have been included, but general feedback from players so far is that the frame rate seems a lot more stable across the board. To be honest, the game already runs remarkably well for the Nintendo Switch, so for it to have been improved even further is very appreciated, indeed.
The folowing post from @RyuNewsGotoku should give a nice flavour of what to expect from the update:
Yakuza Kiwami is the first in Ryu Ga Gotoku Studio's franchise to make its way to the Switch, but the first two entries did show up on the Wii U in HD form back in 2013 in Japan. Kiwami is a very welcome Switch port, and we're hopeful that it's just the first in many for Nintendo's hybrid console.
That said, it's certainly not without its frustrations. In our review, we highlighted some difficulty spikes and issues with the overall pacing, but if you're looking to get acquainted with the Yakuza / Like A Dragon series, this is certainly a good place to start.
