Q.Could you tell me the name of the Hayabuchi River?
It is said that the Hayabuchi River was given to mean a river with "Hayaase" and "Fuchi". "Hayase" refers to a place where the flow is fast in the river and white waves are standing on the surface of the water, and "Fuchi" refers to a place where the flow is usually loose with deep water.
Unlike a monotonous river, rivers with Hayase and Fuchis are said to be rivers like rivers where fish and other creatures can easily live. Go to the Hayabuchi River and find out where "se" and "buchi" are.
Q.How many years ago did the Hayabuchi River be made?
It is said that when the Tama Hills was formed about 300,000 years ago, the rain on the hills created the Hayabuchi River.
Once a flow is made, the hills and plateaus will be cut down more and more. When the flow slows down in a flat place, the river bends like a snake.
Q.Tell me the legend about the Hayabuchi River.
There is a legend about swords and snakes related to the Kamakura Highway at Ken Shrine in Eda-cho, Aoba-ku.
In addition, the names of Yabane and Yazakibashi in Eda Higashi-cho tell stories about the fact that a warlord fired bow and arrow from Eda Castle. Explanations are posted on the Tapir bulletin board along the Hayabuchi River on the right bank of Yasashi Bridge.
In addition, there are many interesting stories in the Hayabuchi River basin, such as the water struggle of the Hayabuchi River, the spring of the Reisen of Ryoma Kajiyama Fudoson, and the legend of the reserves of Chigasaki Castle.
Q.Have you ever heard that the typhoon flooded the outside of dike?
The Hayabuchi River and Tsurumi River have long been called the "Rag river", and during typhoons, dike often broke down. It is famous for the floods of 1938 and 1941.
After the war, the Hayabuchi River basin was widely flooded by the Kano River Typhoon in September 1958 and Typhoon No. 4 in 1966.
In addition, Typhoon No. 2 Muroto in 1961 and Typhoon No. 17 in 1976 were also severely damaged.
Q.When did the concrete embankment be built?
There is a record of river renovation work from May 1969 to March 1968 (83).
When the river was renovated, it was developed as an urban river surrounded by concrete and fences. Recently, seven "water staircases" that descend to the Hayabuchi River have been improved in response to disasters. Two of them are usually locked, but the remaining five can descend to the surface of the river with caution.
In addition, a waterfront plaza is under construction where the subway connecting Centerminami and the north crosses the Hayabuchi River.
Q.How is the water of the Hayabuchi River used?
Is it used for something?
It falls on the land on both sides of the river and transports it to the sea so as not to overflow the rainwater collected in the river to prevent flooding. In addition, it is useful for plants on the riverbank and creatures in the river on the way.
People don't use the water of the Hayabuchi River for anything on the way, but both sides of the river have a scenic promenade, making it a place for everyone to relax.
