DESCRIPTION
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.
Every detail, from the deep red-tinted hamon to the finely wrapped black silk ito, speaks of mastery and balance. The glossy black saya completes the piece with its reflective finish, symbolizing calm over chaos — a warrior’s flame hidden beneath the surface.
