Kawaguchi Shinden

Japanese: 川口新田 - かわぐちしんでん

Also known as Osaka River Mouth Sea Surface New Fields, this is the general term for the new fields developed over a period of approximately 260 years in the western area of present-day Osaka City from the early Edo period to the end of the Edo period. The marshes and deltas at the mouth of the Osaka Bay coast are the newest alluvial deposits in the Osaka Plain, and as land was turned into land, the development of new fields through reclamation began in the early 1600s. However, during the Genroku period (1688-1704), soil discharged from the headwaters of the various rivers leading to the three Osaka towns accumulated on the Kizu River, Aji River, Shirinashi River, and Denpo River, among other rivers, making it difficult to transport by boat to the river mouths.

Japanese:

大坂川口海表新田ともいい，現大阪市西部一帯で江戸初期から幕末まで，およそ260年間にわたって開発された諸新田の総称。大阪湾岸河口部の沼沢地やデルタは，大阪平野のうちでは最も新しい沖積層で，陸化の進行にともない，1600年代の初めごろから，干拓にともなう新田の開発が進められたが，元禄年間(1688‐1704)になると，大坂三郷に通ずる諸河川の源流から放出される土砂は，木津川，安治川，尻無川，伝法川などに堆積し，川口への舟運が不便になった。
