A stone like a sumi-mark was left on a slab-like stone from the archaeological site of Matsue city, which seems to be a mid-Yayoi period suzuri. According to the researchers surveyed, it is thought to be about 2000 years ago, and if it is a letter, it is the oldest example in Japan.

This slab-like stone had previously been excavated from the Tawayama archeological site in Matsue City, and was again investigated by visiting professor Yasuo Yanagida of Kokugakuin University.

As a result, it was thought that the stone was used as a slush in the middle of the Yayoi period about 2,000 years ago, and it was found that something like ink writing was left behind.

When multiple researchers confirmed, it was determined that the two characters were arranged vertically, and the upper character could be "child" of the child, and the lower character could be "bo" although it was not clear. And

In the Japanese archipelago, letters were used reliably around the 5th century during the Kofun period, and earlier in the late Yayoi period, pottery engravings that were considered to be letters were found, but if this is a letter, It seems to be the oldest example in Japan.

Mr. Yanagita says, "There are two characters, so they are not considered to be symbols. In the middle of the Yayoi period, letters were likely to spread and be used for exchanges at bases in western Japan."
