An urawaza (Japanese for "secret trick") is a quirky, ingenious technique that optimizes an everyday activity like cleaning up spills, preventing odors, or folding laundry. In Japan, urawaza have been shared by word of mouth and passed down to descendants for centuries. In the aftermath of World War II, urawaza helped the population make best use of scarce resources, like using alcohol instead of more expensive household solvents for cleaning. Lifestyle urawaza were popularized in the Japanese television series Ito-ke no Shokutaku (The Ito Family Dinner Table), incorporating many viewer-submitted tips. The term itself became globally popularized when video gamers in the 1980s began sharing their game-related urawaza online.
