Japan’s global reputation as one of the cleanest countries in the world did not come from nowhere. Today, its streets are free of litter, and even public toilets are spotless and welcoming. This cleanliness isn’t just superficial—it’s a deep cultural value embedded in the everyday behavior and mindset of its people.
But just a few decades ago, Japan was far from “clean.” During the Showa era, many homes outside urban areas relied on pit latrines. Public toilets were dark, unhygienic, and often avoided. The streets, too, were far from immaculate.
The transformation began in an unlikely place: the toilet.
In the 1980s, Japan introduced the world to a revolutionary idea—cleaning with water. The arrival of the “washlet” changed everything. It transformed the toilet from a place of mere necessity into a clean, comfortable, and even aspirational space. People began to value hygiene in new ways. The home changed. Then the neighborhood. Then society.
The toilet sparked a cultural shift—one that led Japan toward becoming a cleaner, more dignified nation.
This is why we created KIREI. KIREI is a return to the roots of water-based hygiene—an affordable, electricity-free solution inspired by Japan’s “washlet revolution.” It brings the beginning of clean to places where it's most needed, solving sanitation challenges around the world.
‘Clean’ is not just a condition.
It’s culture.
It’s pride.
It’s hope.
KIREI is where a cleaner society begins.
