One of the World’s Oldest Samurai Swords Was Discovered in an Attic

Experts now believe the samurai sword was first crafted in the 12th century and is considered one of the most significant finds in Japanese history. 

According to Japan Forward, the shrine’s officials had no idea of the sword’s rarity at the time, so it was simply returned to storage.

During the blade’s wetting in 2016, shrine officials realized they had an extremely rare blade in their possession.

It was created during the Heian Period of samurai, which is important for several reasons, the most prominent being that this was when curved samurai blades came into existence. 

It appears that the heirloom, “made in the Heian Period (794–1185) for a samurai and initially passed down through his family, was presented to the shrine sometime from the Nanboku-cho Period,” said Miyazaki.

The rare kohoki sword is one of 12 blades discovered in the shrine. However, none are as valuable or as old as the one found at Kasuga Taisha. 

However, some suggest it bears a striking resemblance to the famous Doji-giri sword, which is on display in the Tokyo National Museum. This could suggest it was made by the mastersmith Yasutsuna. 

He went on to say it “is a very important example of work of the period in excellent condition” (via Japan Forward).

He continued, “probably donated to the shrine by someone wishing for divine protection by the residing deity” (via Japan Forward).

According to experts, the Hon’ami family has been a trusted polisher since at least the Kamakura period, which began in the 12th century. 

The process involved meticulous polishing to reveal the original craftsmanship, highlighting the unique attributes of the Ko-Hoki school techniques used centuries ago.

This transformation was crucial in the development of samurai warfare. The school’s techniques were innovative, influencing swordsmiths throughout Japan and setting a new standard in sword craftsmanship.

The process included careful layering, folding, and tempering of steel, producing blades renowned for their durability and sharpness. These swords were weapons as much as they were works of art, reflecting the cultural and technical zenith of the era.

The Kasuga Taisha sword, likely imbued with such spiritual values, served as more than just a martial tool. It was a sacred object, revered within the shrine’s community.

These efforts are vital for historical documentation and help in understanding the broader context of Japanese sword-making traditions and the specific era of the sword’s creation.
