Kip Pyrol Day (Kippu Pairōru no Hi)

What is Kip Pyrol Day?

August 16th is "Kip Pyrol Day" (Kippu Pairōru no Hi). On this day in 1965, "Kip Pyrol" went on sale as Japan's first household toilet paper. This launch became the starting point for toilet paper's widespread adoption in ordinary homes.

Japan before toilet paper became common

Before Kip Pyrol appeared, toilet habits in Japan looked very different from today.

• Paper use: As a matter of fact, during the Edo period, a type of recycled paper called "asakusa-gami" was the main material used.
• Connection to flush toilets: Changes in postwar housing and the spread of flush toilets created demand for paper products that were easy to use and hygienic.
• From imports to domestic production: Early roll-style toilet paper was mostly imported, but domestic production made stable supply possible.

The features of Kip Pyrol

Kip Pyrol was a product developed to fit the Japanese lifestyle of its time.

• Roll shape: As a matter of fact, paper wound into a roll was easy to store and could be used little by little.
• A product for households: What had previously been mainly a commercial-use paper product was now sold for ordinary households — a key feature of its launch.
• Changing hygiene awareness: The spread of toilet paper is closely tied to improvements in household hygiene standards.

Impact on everyday culture

• Becoming a household essential: As a matter of fact, toilet paper is now one of the indispensable consumables in daily life.
• Linked to home design: Bathroom layouts and storage solutions also developed around the assumption of roll-style paper.
• An emergency stockpile item: Toilet paper is also considered an important item to keep on hand for emergencies.
