Great Discovery of the Century
 
Excavation of bronze sword
  ■358 bronze swords
When it was discovered in Kojindani, the total number of copper swords were excavated nationwide, but in Kojindani, 358 copper swords of the same shape in four rows were excavated at once. This discovery was a major event that urged the review of bronze ware research in Yayoi period.

■6 bronze dots and 16 bronze contradictions
The combination of six bronze dots and 16 bronze swords buried in the immediate vicinity of 358 bronze swords has never been unprecedented. Dotaku is the oldest type in Japan, and the discovery of Kojindani bronze ware has triggered a great interest in Yayoi period, such as the bronze contradiction found in northern Kyushu.

■What is a copper sword?
 

Copper sword

Copper swords were introduced from the continent at the beginning of the Yayoi period as a practical weapon, and since they were made in Japan, and turned into rituals. All of the 358 bronze swords that were excavated are said to be a medium-sizedIzumo type copper sword.
"X" was engraved on the part of 348 of the 358 trees. The only examples with this mark are those excavated from the Kojindani archeological site and the neighboring Kamo Iwakura archeological site. The meaning of "x" is still a mystery, but it is also considered to be "connecting divine spirit here," that is, to prevent the power of the buried sword from escaping.
■What is a bronze dot?  
The bronze dot is said to be the money that invites God. The roots are said to be small local bells attached to livestock necks in China and the Korean Peninsula. Yayoi period At the end of the first half of the year, it gradually grew larger and used as a tool for festivals. The bronze dot was actually sounded (a bronze dot), but it gradually became larger and changed to something that could only be seen from a distance without sounding (a bronze dot).

■What is a copper contradiction?  
Coppers

The bronze contradiction was used as a tool for Matsuri along with a bronze sword and bronze dot.
It is thought that bronze swords and bronze contradictions used evil spirits, while the bronze dot was money that calls God. In the first half of the Yayoi period, the copper sword was a "slender" weapon with a handle to the bag at the base. However, from the middle term onward, it will become larger and more practical, and will change to non-practical "medium-size", "Nakahiro shape" and "wide shape". The mold soil remained in the bag of all copper contradicts found in Kojindani. This is thought to have been used as a ritual rather than using the copper contradiction as a weapon.
