A kamon is a traditional Japanese family crest.
The word literally means:
家 (ie) — family
紋 (mon) — emblem / crest
For hundreds of years, Japanese families used kamon to represent their lineage — similar to coats of arms in Europe.
But unlike many European crests, kamon are usually:
• simple
• symmetrical
• highly stylised
• black and white
They often feature natural imagery such as:
🌸 flowers (like cherry blossom or wisteria)
🍃 leaves
🐢 animals
☀️ celestial symbols
Samurai families displayed their kamon on:
• armour
• helmets
• banners
• clothing
It helped identify allies and signal loyalty during battle.
Even today, kamon appear on:
👘 formal kimono
🏯 traditional architecture
🎎 festivals
📜 wedding garments
Many modern companies even use kamon-inspired logos.
The History of the Mitsubishi Logo:
The famous three-diamond logo of Mitsubishi isn’t just a modern corporate design.
It comes from samurai family crests (家紋・かもん).
The name “Mitsubishi” (三菱) literally means:
三 (mitsu) — three
菱 (hishi / bishi) — water chestnut
The water chestnut leaf is diamond-shaped — which is why the logo looks like three diamonds.
But the design actually combines two family crests:
• The crest of the founder’s family (Iwasaki family) — three stacked rhombuses
• The crest of the Tosa clan, who were his feudal lords — three oak leaves arranged in a triangle
When Iwasaki Yatarō founded Mitsubishi in 1870 as a shipping company, he merged these two crests into a single symbol.
The result?
Three diamonds forming a powerful triangular mark.
JAL logo:
The logo of Japan Airlines (JAL) features a red crane inside a circle.
This crane is called the “Tsuru” (鶴).
But it’s not just decorative.
In Japanese culture, the crane symbolizes:
• longevity
• good fortune
• loyalty
• safe journeys
For an airline, that symbolism is perfect.
🧠 Why This Matters
Kamon reflect something deeply Japanese:
identity connected to family and tradition.
They’re minimalist — but meaningful.
Quiet — but powerful.
And interestingly, there are said to be over 20,000 different designs in Japan.
