Japan's toilet paper habits date back to the 1930s when the country began introducing Western-style toilets. At the time, the country's sewage systems were not equipped to handle large amounts of toilet paper, so it became common practice to dispose of used toilet paper in a separate bin. While it is possible to flush toilet paper in some parts of Japan, it's important to know where and when this is allowed. Following proper bathroom etiquette rules such as disposing of used toilet paper correctly and washing your hands thoroughly after use will help ensure a comfortable experience for everyone using the facilities.
