The traditional Japanese custom of removing shoes before entering a home or traditional building—known as genkan culture—is rooted in centuries of history, cleanliness, comfort, and spiritual purity. Historically, homes featured raised wooden floors covered with woven straw tatami mats, which were easily damaged by dirt, mud, and debris brought in from outside. Additionally, traditional Japanese lifestyle practices involved sitting, eating, and sleeping directly on the floor mats, making maintaining pristine indoor cleanliness an essential part of daily household hygiene and respect.
