ただいま。 — I'm home! (Cultural · Greeting, Casual — to friend, JLPT N5)

Gesture & etiquette

Call out toward the interior of the home as you enter; remove shoes in the genkan (entrance foyer) before stepping up; it's common to kick off shoes and face the door to align them neatly as you say this.

This exchange — 'ただいま' (I'm back) / 'おかえりなさい' (Welcome home) — is one of Japan's most comforting daily rituals. It signals that the household acknowledges the person's safe return and reintegration into family space. Skipping it even once can feel quietly jarring to Japanese family members. Historically, the phrase is short for 'ただいま帰りました' (I have just returned).
