📝 Product Review & Background

This katana is mounted in Toppē-gusoku koshirae, a distinctive style characterized by a sharply protruding scabbard end.
The saya is richly decorated with rolling cloud motifs and dragon engravings, with fully carved copper fittings at the koiguchi, kurikata, and kojiri, creating a striking and luxurious appearance.

The blade form is inspired by Kogarasu-maru, one of the most legendary blade styles in Japanese history—often described as neither fully sword nor fully katana.
According to legend, Kogarasu-maru was a divine blade gifted by a sacred bird to Emperor Kanmu, giving it a strong mythological and symbolic background.

This modern interpretation uses hand-forged manganese spring steel, offering a balance of high hardness and excellent flexibility, making it a very capable performance blade.
The combination of a true hand-cut bo-hi and traditional white polish significantly elevates the blade’s visual presence.

Whether you are looking to experience a unique historical blade shape, enjoy a different handling feel, or add a visually impressive piece to your collection, this katana is highly recommended for both use and appreciation.
