Okarishimasu
Okarishimasu is a Japanese phrase commonly used when returning home. It is typically said by the person entering their house after being out. The literal translation is often rendered as "I have returned" or "I'm home." This expression serves as a polite acknowledgement of one's arrival and can be directed towards family members or other occupants of the residence.
The counterpart to okarishimasu is okaeri nasai, which is the greeting offered to the person returning home.
