Although I suppose it is no longer common for people to call, "Honey, I'm home!" in America when they get home from work these days, in Japan it is still common to say, "Tadaima." This literally means "right now" but in usage it means "I'm home." And whoever is in earshot will typically reply, "okaerinasai" which essentially means "welcome home." But when I come home, all I hear is "Jama!"
