The Kokuenmaru 黒炎丸 is an expression of restrained ferocity — a katana forged for those who understand that true power is silent. Its blackened copper dragon tsuba coils protectively around the blade, while the golden chrysanthemum crest etched near the habaki recalls the dignity of Japan’s imperial lineage.
