The publisher's announcement adds another notable commercial achievement to Capcom's recent string of high-performing releases.
Onimusha began as a PlayStation 2-era action series, with the original Onimusha: Warlords launching in 2001.
The franchise has been historically well regarded among action-adventure fans, even if it did not reach the same commercial heights as some of Capcom's other major IP.
The newly released Way of the Sword represents a modern revival of the series on current platforms.
Capcom has not disclosed platform-specific sales breakdowns for the title.
However, retail sales reporting in the UK shows a heavy tilt toward Sony's PlayStation 5, with the PS5 accounting for approximately 87% of the platform split in UK boxed charts the week of release.
That figure reflects the UK retail landscape for the launch week but does not represent Capcom's full global digital-plus-physical sales mix.
Nintendo Life, in its review, awarded Onimusha: Way of the Sword a score of 9/10.
The outlet described the release as a successful revival of Capcom's samurai franchise that advances the series' gameplay while maintaining its core identity.
Recasting the reviewer's assessment in journalistic terms: Nintendo Life concluded that the game effectively modernizes Onimusha's mechanics and presentation without losing the franchise's defining elements.
Comparative context cited by the publisher and industry sources places Onimusha's day-one performance alongside other recent Capcom launches.
For example, Pragmata reportedly reached 1 million sales within two days of release, while Resident Evil Requiem recorded over 5 million units sold in under a week.
Those figures illustrate Capcom's strong commercial momentum across multiple franchises.
For consumers and industry watchers, the immediate takeaways are clear: Onimusha: Way of the Sword has delivered a significant launch for Capcom, the Onimusha franchise now exceeds 10 million cumulative sales, and early retail data shows strong PlayStation 5 representation in the UK market.
Capcom's official statements remain the primary source for final global tallies and future platform breakdowns.
