A genkan is a traditional Japanese entryway found in homes and some buildings. It serves as a space where people can remove their shoes before entering the main living area. This practice helps keep the interior clean and is an important aspect of Japanese culture. Typically, the genkan features a lower floor level compared to the rest of the house, often with a small step up. It may include a shoe rack or storage area for footwear. The genkan is also a place for greeting guests, making it a significant transition space between the outside world and the home.
