Some years ago, I developed an interest in ô-kozuka. These are kozuka that are larger than the norm and were mounted on especially wide and long wakizashi. I have collected quite a few over the years and will be posting them to the gallery section of the website over the immediate future.
This is the largest one in my collection. it is unsigned but it is attributed by the NBTHK to the Kaga Gotô school. This is a side school of artists from the Gotô school who worked for the Maeda Daimyo in Kaga Prefecture during the Edo era. This kozuka is done in shakudo with the reverse done in gold. It depicts dragons frolicking among the waves. The image below contains a kozuka of “normal” size for a comparison. This baby is huge and beautiful. It measures 5 3/4 inches by 7/8 inches.
