These days, many companies are branching out, dabbling in unexpected ventures beyond their core business, often surprising and delighting the public.
In a surprising move, Kao's home cleaning division is making its debut in the gaming world, launching a 3D exploration horror action cleaning simulation game called "Shizukana Osouji" (Silent Cleaning). Yes, you read that right – the same Kao that makes your detergents is now making games! It officially hit Steam on August 8th, and here's the best part: it's absolutely free to download! The game is expected to be available until August 7, 2026.

The game's protagonist has just inherited their deceased father's villa and plans to clean it up before selling it to a real estate agent. As players tidy up, they'll uncover passwords, mechanisms, and notes hidden throughout the kitchen and various rooms, piecing together the secrets their dad left behind. So, it's essentially a massive inherited villa clean-up, with a side quest to unravel a family mystery?
Each stage features unique mechanisms that players must tackle using cleaning tools (all, naturally, Kao brand products). Some levels even let you combine different products to unleash "secret tips" that boost cleaning efficiency and help solve the puzzles!




Now for the spooky bit – you might not be alone in the house! Unidentified creatures will approach based on your cleaning sounds or footsteps. You'll need to stay constantly vigilant, minimize your presence, and keep cleaning under pressure while figuring out how to escape.
This game boasts multiple endings, determined by your cleaning completion rate and clear time, encouraging players to challenge it repeatedly and unlock every outcome.
This wildly unexpected project actually sprang from Kao's home cleaning division. They stated, "We want people to discover, through entertainment, that cleaning can be simpler and even fun!" This game is the direct result of that vision.
The game also heavily features Kao's own cleaning products, not just as in-game items, but also subtly teaching you the most effective ways to use them in real life. It's like learning cleaning hacks while you play!


The biggest draw of this game is how it blends two seemingly contradictory emotions: the "super therapeutic satisfaction of cleaning" and the "heart-pounding tension of being chased by a ghost." With fright and fun intertwined, doesn't it make you want to give it a try? Plus, the game is streamer-friendly, allowing content creators to freely livestream and monetize their gameplay without needing extra permission – a huge win for anyone looking to make videos or stream their experience.
It's available for free download on Steam right now, so if you're curious, why not give it a whirl?
