愛 (Ai) Kanji Meaning — The Japanese Symbol of Love Explained

It’s not just about romance.

When people see the kanji character “愛 (Ai)”, they often think it simply means “love,” perhaps in a romantic sense.

But the story of Ai goes much deeper.

Its origins lie in the image of the human heart, and its many readings reveal a vast spectrum of emotion, from joyful adoration to a beautiful, heart-aching tenderness.

Over time, this single character grew to embody not only romance, but also compassion, cherishable affection, and the profound, sometimes painful, connections that bind us together.

The Origins of the Character

The kanji 愛 is a complex character with a rich history. The most crucial component is at its center:

• 心 (kokoro) — meaning “heart”

The character’s ancient form depicts a heart (心) along with other elements that suggest a person looking back or hesitating (夊), as if overcome with powerful emotion.

The overall image suggests a feeling so profound that it originates in the heart and affects one’s entire being.

This etymology perfectly supports the complex emotions found in its many readings.

The true depth of this character is revealed in its many readings, each carrying a unique shade of meaning.

On-yomi (Sino-Japanese reading)

• ai (アイ) — This is the most common reading, used in countless compound words that form the foundation of love in society, such as aijō (愛情, affection) and ren'ai (恋愛, romantic love).
