Please take off your shoes in the entranceway.
The most mysterious thing that's connected to a house is the entranceway. When you're walking into one you never know what's coming next. You just take off your shoes and hope the rest of the house isn't really weird or something. If it is, the entryway is then your only way out.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
