Abe River


July 5, 2022

The Abe River is a river that flows through Aoi Ward and Suruga Ward, Shizuoka City, Shizuoka Prefecture. It is the main stream of the Abe River, a first-class water system. It is also famous as a clear stream, and its underground water is also used for tap water in Shizuoka City. Although it is a large river, it is a rare river with no dams under the River Act in the main stream and tributaries. .. There are also notations such as "Abegawa" and "Abegawa", but these are incorrect. One of the specialties sold at the foot of the Abe River is "Abekawa Mochi", but outside the local area, the way to eat mochi with soybean flour is sometimes simply called "Abekawa".


It originates from Otanimine, Hachikomine, and Abe Pass on the border between Shizuoka and Yamanashi prefectures. The slope of the headwaters of Otani Ridge (elevation about 2,000 m) is called "Oyakuzure", and it is said to be one of the three major collapses in Japan along with the Hiedayama landslide in Nagano prefecture and the Tonbiyama landslide in Toyama prefecture. The entire basin is in Shizuoka City, and a river Nakajima called "Funayama" can be seen near the confluence with the Warashina River in the lower reaches, flowing to the west of the city and pouring into Suruga Bay. The Itoigawa-Shizuoka Tectonic Line runs nearby, and there is a boundary near this river where the geological structure differs greatly between east and west. As of 2019, downstream fishing is prohibited.


There are various theories about etymology. Derived from Abe-gun. Named after Mr. Abe. This theory is considered to be the most influential. "Abe" means lowland. It is derived from the Ainu word "Ape" (Tue).

Early Edo period --- Ieyasu Tokugawa carried out a large-scale hydraulic work as a general contractor, and it is the current flow. Before that, it was poured into Suruga Bay as multiple rivers in a different flow from the Warashina River, but due to large-scale hydraulic engineering work, it began to join the Warashina River. It is said that the area downstream from the current confluence was the Warashina River. In particular, the embankment that is said to have been built on the left bank of the Abe River by the Satsuma Domain is called the Satsuma Bank (the Satsuma Domain's involvement in the embankment has not been completely proven). (Because the new embankment was built inside, most of the old Satsuma embankment is now a road and is called "Satsuma-dori"). 2008-Selected as one of the "100 Exquisite Waters of Heisei" by the Ministry of the Environment. June 2017-The amount of rainfall is extremely low, and from the beginning of the year, a "separation" that interrupts the river channel occurs (from the vicinity of Kano Bridge to the vicinity of Anzai Bridge).

Culture of the Abe River

During the Edo period, bridge construction was not permitted for defense reasons. Therefore, travelers had to board a ferry, a piggyback or a pedestal to cross the river. The state of this passing has been the subject of paintings and literature since that time, and has appeared in "Tokaido Nakagiri Kurige".
