How Long Is Onimusha: Way of the Sword?

How long Onimusha: Way of the Sword takes

Onimusha: Way of the Sword is about 20 hours for the main story. For completionists, the better verified figure is 60–70 hours for the platinum trophy, which is far more representative of a full run.

That is the clearest answer available from post-launch measured data. The old pre-launch ~20-hour estimate was only a rough secondary figure, but the shipped-game completion data now shows that the story is only part of the time investment.

Main story length

The main-story estimate that has held up is approximately 20 hours. That matches the long-standing figure attributed to Wikipedia, but now it sits alongside a much firmer completion estimate from PowerPyx.

This matters because Onimusha: Way of the Sword is not built like a short, one-and-done action game. The shipped version includes:

• New Game+
• Carnage difficulty
• 274 collectibles
• 18 boss encounters
• 18 Chance Encounters

So if you only want to clear the campaign once, around 20 hours is the right ballpark. If you want to do everything, expect a much longer commitment.

Completionist and platinum time

For players asking “how long to beat” in the full sense, the strongest verified completion number is 60–70 hours for the Platinum trophy.

PowerPyx’s roadmap says that estimate comes with:

• a stated difficulty of 6.5/10
• 52 trophies total
• 1 Platinum, 2 Gold, 9 Silver, and 40 Bronze
• a minimum of two playthroughs

That second playthrough matters because Carnage is locked behind beating the game and is only available in New Game+. In other words, the platinum is not just “do the story and clean up a few extras.” You must clear the game, then go back in for the harder route.

Why the full run takes so much longer

A few shipped-game systems explain the jump from the story estimate to the platinum estimate.

New Game+ carries some things, but not everything

PowerPyx’s shipped-game guide says these carry over:

• Revival Mirrors
• healing supplies
• charms
• skill upgrades and awakened abilities
• Hozuki Pouches
• Genma Notes
• Lion Dogs

These do not carry over:

• equipment enhancements
• Mysteries of Kyoto
• Chance Encounters
• clothing

That means your second run is not a clean repeat. You keep important progression, but you still have to re-clear major content and rebuild parts of your equipment path.

Collectibles and side content add real time

PowerPyx lists 274 total collectibles, including:

• Mysteries of Kyoto
• Chance Encounters
• Lion Dogs
• Oni Armaments
• Hozuki Pouches
• Charms
• Genma Notes
• Power Stones
• Oni Stones
• Fine Silk Cloths
• Tamahagane

That kind of checklist adds hours on its own, especially if you are also chasing upgrade materials and trophy-specific requirements.

Carnage difficulty forces a second clear

Carnage is not just an optional challenge mode. It is part of the completion path, and it is why the platinum estimate lands in the 60–70 hour range instead of something lower.

Is the game really only 20 hours?

If by “beat” you mean “finish the campaign once,” then yes, about 20 hours is the best available estimate. If by “beat” you mean full completion, then no — that number leaves out a lot of the game’s actual time demand.

The most honest way to phrase it is:

• Main story: about 20 hours
• Completionist / platinum: about 60–70 hours

That is the cleanest answer for launch-window searchers, and it lines up with the shipped data rather than a pre-launch guess.

What time should different players expect?

Goal	Verified time estimate	Notes
Main story	About 20 hours	Best current estimate for a standard clear
Full completion / platinum	60–70 hours	PowerPyx estimate; requires at least two playthroughs
Casual story + some extras	More than 20 hours	Depends on collectibles, side missions, and difficulty

Bottom line

If you just want the answer in one line: Onimusha: Way of the Sword takes about 20 hours to finish the story, and about 60–70 hours for completionists going for the platinum.

That gap is normal for a game with New Game+, Carnage difficulty, 274 collectibles, and a second mandatory clear. So the real answer depends on how far you plan to go.
