「倉賀野」という地名の由来を考える

　私が生まれ育った倉賀野という地名の由来は「崖の上の野原」という風に考えられると、以前に倉賀野についての研究者の講演会で聞いたことがあります。つまり、昔は「崖のことを倉」と言ったようです。その一例として、群馬県北部に位置する谷川岳には有名な「一ノ倉」という名の物凄い絶壁の山があります。

　倉賀野町を烏川を隔てた南隣の阿久津町の方から眺めると、確かに、倉賀野は東から西までずっと崖の上に成り立っていることが分かります。このため、倉賀野は大昔から水害に見舞われることがなく住みやすかったのでしょう。烏川近くの崖の上のみならず、倉賀野には数か所で遺跡が見つかってます。

　ところで、現在、私が住んでる土地は以前は畑であり、少し掘ると今でも浅間砂が出てきます。天明三年の浅間の大噴火では倉賀野にも火山灰が厚く降り積もり、田が大打撃を受け、人々は降った灰を集めて灰塚としたと伝えられます。このため、私の土地は灰塚の一部だったと考えられます。

　しかし、それとは比較できない大昔の石器時代より、人々は倉賀野に住み着いていたのでしょう。１０年ほど前に私は庭いじりをしていたとき、写真上の鋭い刃を持った「打製石器」、また、木の実などを潰したと想われる「楕円形の石と球体の石」を発見し、今でも保存し、何万年もの大昔から、この地に人々が住んでいたことに思いを馳せてます。

Dear my overseas friends who like both of nature and great music

　The simultaneous interpretation for your understanding will be done after my radio gymnastics held in the nearby park and breakfast in Japan time.

I once heard at a lecture by a researcher about Kuragano-town that the origin of the name of the place where I was born and raised, Kuragano can be thought of as "a vast field on a cliff." In other words, in the old days, "cliff" was called "kura" in Japan. As an example, there is a famous mountain called "Ichinokura" on Mt. Tanigawadake in northern Gumma Prefecture, with a steep cliff beyond description.

When we look at Kuragano-town from the neighboring Akutsu-town across the Karas River to the south, we can see that Kuragano is indeed existed on the long cliff from east to west. For this reason, Kuragano-town has never been hit by floods since ancient times, I guess and has been easy to live in. Ruins have been found in several places in Kuragano-town, not just on the cliff near the Karas River.

Not change the subject, but the land where I currently live was formerly a field, and even now, if I dig a little, I can find the active volcano Mt. Asama's sand. It is said that during the great eruption of Mt. Asama in 1783, thick layers of volcanic ash fell on Kuragano, of course, it caused great damage to the rice fields, and people collected the volcanic ash and made it into ash mounds called Haizuka in our tongue. For this reason, it is believed that my land was a part of the ash mound.

However, people have been living in Kuragano since the incomparably ancient Stone Age. About 10 years ago, while I was working in my garden, I discovered a chipped stone tool with a sharp blade, as shown in the photo, as well as oval and spherical stones that are thought to have been used to crush nuts. I have still preserved these, and they make me think about the fact that people have been living in this land for tens of thousands of years of Stone Age.
