How much better would 24 bit sound, and was it on the JP release of Katanagatari?
No better at all.
As far as I know, not a single human being has been able to demonstrate that they can hear the difference between 16 bit and any higher bit depths. The vast majority of people are actually unable to hear any difference between 14 bits and higher depths, and even that only after training.
More than 16 bits per sample is pure waste.
