1. 会釈 (Eshaku) – The Light Bow (15° Tilt)

This is the most common type of bow used in daily interactions. It’s a quick, slight nod of the head or a small forward bend, typically used when greeting acquaintances, coworkers, or passing someone in the hallway.

Example: When saying こんにちは (Konnichiwa) to a colleague at work, you might give a light bow to acknowledge them politely.

2. 敬礼 (Keirei) – The Respectful Bow (30° Tilt)

This bow is deeper and used in more formal settings, such as business meetings, customer service, or when addressing someone of higher status. It's a way to show extra politeness and sincerity.

Example: When a store employee welcomes a customer with いらっしゃいませ (Irasshaimase), they often pair it with a keirei bow to show respect.

3. 最敬礼 (Saikeirei) – The Deep Bow (45°+ Tilt)

This is the most profound form of bowing, reserved for serious apologies, expressing deep gratitude, or formal ceremonies. It is a sign of utmost respect and sincerity.

Example: If someone makes a mistake at work and says 申し訳ございません (Moushiwake gozaimasen), they will bow deeply to show genuine remorse.

Understanding these bowing styles helps foreigners interact more naturally in Japan—ensuring they use the right greeting for the right occasion.
