I've only played Berseria and Symphonia, but neither in Japanese. My bet is that they are not good either as Bandai pretty much butchers the Soulsborne series to the point that the lore youtubers have to resort to fantranslators to confirm their theories. The biggest offenders are Nintendo (Treehouse), Nisa America, Koei, Xseed, Sega and SQEX. By what I have seen most localizers are friends with each other in the industry, so you can bet they follow similar work philosophy.
