Bowing is nothing less than an art form in Japan, respect pounded into children’s heads from the moment they enter school. For tourists, a simple inclination of the head or an attempt at a bow at the waist will usually suffice.
The duration and inclination of the bow is proportionate to the elevation of the person you’re addressing. For example, a friend might get a lightning-fast 30-degree bow; an office superior might get a slow, extended, 70-degree bow. It’s all about position and circumstance.
