There are certain things you can find in a Japanese house that would be missing in most homes in the U.S., such as a traditional tatami room with paper shoji doors, a washing machine with a hose to let you wash your clothes with last night’s bath water, and a toilet that cleans your butt for you when you’re done. Another thing that homes in Japan have is a genkan, the recessed area located just inside the front door where Japanese people leave their shoes before entering a home and some businesses (including J-List). The Japanese might not think twice about their own shoe-removal culture, but it can be quite interesting if you’re learning about the country from the point of view of an outsider. In anime and Japanese doramas a story might revolve around a girl who opened the front door to her boyfriend’s apartment to see from the shoes left in the genkan that he was entertaining another girl, a subtlety which might be missed by Westerners. Similarly, the sight of a genkan overflowing with shoes is a cultural signal that a heck of a party going on, although this might not be immediately apparent to us. In the anime Toradora, you can immediately tell the respective personalities of the two main characters from how they remove their shoes: neat-freak Ryuji lines his up carefully, while the wild Taiga kicks her shoes off with abandon.
A lot of information can be communicated by a Japanese genkan.
