新潟についてすごく調べてる人なので、話聞くのが面白い。何でも突き詰めると面白いんだな。車で新潟島の海に面しているところまでドライブしてもらい、海風に当たる。それから新潟市歴史博物館みなとぴあまで乗せてもらって、大変ありがたかった！やはり新潟は車社会である！ みなとぴあでは新潟の、川との闘いの歴史が見られて、大変興味深かった…。特に、江戸時代に、増水した分を分流させる松ヶ崎掘割を作ったが、翌年の増水に耐えられず、阿賀野川の水が堀を押し流してそこが支流となってしまった。てのが…。地形が変わってしまったとは。江戸時代の木と石の土木工事では川の強さに勝てなかった、というのも、時代の流れを感じる。。
My Niigata friend is a person who did a lot of research on Niigata, so it is interesting to listen to his stories. I guess everything can be interesting when you get deep down to it. He drove me to a place facing the sea on Niigata Island to enjoy the sea breeze. Then he gave me a ride to Minatopia, the Niigata City History Museum, which is otherwise kind of inconvenient to get to! Niigata is, after all, a car-based society. At Minatopia, it was very interesting to see the history of Niigata's struggle to control the rivers and flooding.... In particular, during the Edo period, the Matsugasaki ditch (?) was built to divert rising water of the main stream of Agano river, but it could not withstand the rising water pressure the following year, and the water of the Agano River swept the ditch away, making it a tributary. A half-year's construction work was just gone in one flooding, changing the topography. The civil engineering technology of wood and stone in the Edo period was no match for the strength of the river. We've come a long way since then, for sure.
