This episode explains the Japanese custom of ojigi, or bowing, which is a vital form of non-verbal communication expressing deference and social standing. It outlines three primary types of bows, each varying in their degree of formality, angle, and appropriate use:

Eshaku is the most casual bow at about 15 degrees for informal greetings.

The more formal Keirei involves a 30-degree bend and is frequently used in professional environments or when addressing superiors.

Finally, Saikeirei is the deepest and most respectful bow, exceeding 45 degrees, reserved for profound apologies or showing the utmost respect.

Proper bowing etiquette also dictates maintaining a straight back, avoiding direct eye contact, and specific hand placement depending on gender.
