Description
This is a matched daishō set consisting of a katana and wakizashi, both with sequential registration numbers—a rare and highly collectible combination. The blades are housed in coordinated koshirae (mountings), giving them a beautiful sense of unity and harmony when displayed together.
The katana features a refined suguha (straight hamon), with clean lines that emphasize sharpness and precision.
In contrast, the wakizashi displays a striking ō-gunome midare hamon, a bold and dynamic pattern of large and small undulations.
This thoughtful pairing showcases two very different expressions of sword artistry, allowing you to appreciate the unique charm of each blade.
Historical Significance
-
Katana: Crafted by Osafune Sukesada, dated Tenshō 2 (1574), from the Azuchi–Momoyama period—a time of great change and warfare in Japan.
-
Wakizashi: Signed by Yokoyama Ueno Daijō Fujiwara Sukesada, from the mid-Edo period, showing a more decorative and expressive style typical of the peaceful Tokugawa era.
Together, these swords form a rare bridge between two historical periods—one born in the age of conflict, the other shaped by peace and prosperity.
