Respect Bow, Keirei (敬礼), 30 degrees: This is where bowing gets respectful. Thirty degrees is actually quite a lot and feels like quite a lot, if you go ahead and do it. This bow is reserved for your boss / other people who are higher ranking than you. You could probably do a little more than 30 degrees if you wanted to, too. You wouldn’t use this bow with good friends or relatives (unless you were making a joke), so save this for people you don’t know / people who are above you on that societal scale.
