Meaning of the Color Green in Japanese Culture

In Japan, green (緑, midori) carries layered symbolism:

• Youth, new life, spring: Fresh leaves, sprouts; "green" = inexperienced (青二才 aonisai – literally "blue two-year-old," but green connotes newness).
• Harmony, peace, calm: Gardens, tea ceremony, forest bathing (shinrin-yoku).
• Nature & abundance: Rice paddies, evergreens, prosperity.
• Samurai tradition: Green cords/lacquer on armor signified courage, strength, nobility.
• Modern: Traffic "go" signal (called ao "blue" linguistically), safety helmets, environmentalism.

Historically, ao (青) covered both blue and green; midori emerged later as a distinct green term.
