Bushidō
The sword that becomes a way.

The Bushidō Ring (武士道) in 925 silver is inspired by the legendary figure of Miyamoto Musashi: samurai, rōnin, and artist. His invincibility fueled the myth and consecrated the “Way of the Sword” as a philosophy of life. His masterpiece, The Book of Five Rings, was not just a fencing manual, but a universal guide to strategy and mastery.
One can know ten thousand things through the profound understanding of one thing.
– Miyamoto Musashi

Protection
Wearing Bushidō means embodying discipline and presence: a talisman reminding us that true strength comes from mastering oneself before mastering the sword.

Origin
Forged in silver, the Bushidō ring evokes the Kabuto helmet and the severe lines of samurai armor. Every detail is a tribute to the warrior’s pragmatism and the free mind that Musashi raised to philosophy.


The Seal
Musashi was both rōnin and artist, master duelist and Zen painter. Bushidō contains this tension between war and contemplation, between the clash of blades and the silence of the void.

The Hidden Side
Every DECEM relic lives on two planes.
On the outside, the face the world can see.
On the inside, the sculpted secret: symbols invisible to others, yet destined for the Custodian alone.
This is the Dark Side method — the rite of engraving the hidden soul of every creation.


Book of Earth (地, Chi)
Book of Fire (火, Hi)
Book of Water (水, Sui)
Book of Void (空, Kū)
Book of Wind (風, Kaze)
Musashi wrote The Book of Five Rings in 1645, shortly before his death. It is divided into five chapters, each named after an element of Japanese cosmology:
-
Book of Earth (地, Chi)
• Foundations of strategic thought
• The “Way of the Sword” as a discipline of life
• Importance of posture, firmness, stability -
-
Book of Water (水, Sui)
• Adaptability as the key: water takes the shape of its container
• Sword techniques, fluidity of movement
• The mind must remain calm yet ready to change -
-
Book of Fire (火, Hi)
• The art of conflict and battle
• Rhythm, timing, aggression, intensity
• Harnessing tension and energy in direct confrontation -
-
Book of Wind (風, Kaze)
• Critical analysis of other schools of swordsmanship
• Differences with Musashi’s style (Niten Ichi-ryū, the “School of Two Swords”)
• “Wind” as the traditions of others that may mislead -
-
Book of Void (空, Kū)
• The most philosophical and spiritual level
• “Void” as supreme understanding beyond technique and form
• Wisdom that allows one to intuit without thinking, to see without seeing
The Way of the Two Swords

My school is called ‘Two Heavens as One’. Its essence is to use two swords as if they were one.”
– Miyamoto Musashi

Wakizashi (脇差) the short sword
Katana (刀) the long sword

The Way
Not ornament. It is discipline and philosophy. It does not dress you: it shapes you.
Bushidō reminds us that the sword is the Way, and the Way is life.
The Spirit on Watch
This is not just a ring. It is the echo of the strategic mind that knows no defeat, the gaze of the samurai who sees in the void the path to freedom.
