The Arakawa River is a waterway
It supported the economy of Edo

The Arakawa River originates from Mount Kobushigatake, a mountain representative of Okuchichibu, and flows into Tokyo Bay. It was known as a rough river, but since the mid-Edo period it has been used for water transportation.
There used to be a wharf in the Sueno area of Yorii-machi, and boats carrying lumber and other goods to Edo traveled up and down the Arakawa River. Meanwhile, if you turn your attention to the Fuupu River, a tributary of the Arakawa River, you will arrive at Yamato Mizu, where water gushed forth from the legend that Yamato Takeru no Mikoto thrust his sword into a large rock face.
The Arakawa River, which supported the economy of Edo, and the Fufu River, which is supported by legends, can be said to have been indispensable to Yorii Town.

Nagatoro Rock Beds, tens of millions of years old
Inheriting the Great Nature

If you go a little upstream on the Arakawa River from Yorii Town, you will reach Nagatoro. Toro (deep water) is a place where the river is deep and calm, and it is a magnificent scenic spot that lives up to its name. Among other things, the rock formations formed by the erosion of crystalline schist formed about 85 to 66 million years ago by the flow of the Arakawa River are said to be a mecca for geological observation.
On the opposite bank, the cliffs formed by the Arakawa River flowing along the fault line, Chichibu Sekiheki, are also worth seeing. Some of you may have guessed it, but yes, it is named after the Sekiheki along the Yangtze River in China.


A bowl-shaped area on the banks of the Arakawa River,
Explore its history

Hachigata Castle, which is said to have been built by Nagao Kageharu, a vassal of the Uesugi clan of Yamanouchi, was a castle that benefited from the strategic use of the river. Later, Hojo Ujikuni entered the castle and it became an important base for controlling Kitamusashi (present-day northwestern Saitama Prefecture). Located on top of cliffs between the Arakawa and Fukazawa Rivers, it is advantageous for both offense and defense, and is said to have repelled even Takeda Shingen and Uesugi Kenshin.
However, during Toyotomi Hideyoshi's attack on Odawara, the castle was surrounded by Maeda Toshiie and Uesugi Kagekatsu, and after a month of fighting, the castle was surrendered. Unfortunately, it did not become an impregnable castle.
Currently, the castle itself no longer remains, but you can still see the moat and earthworks (partially restored). In spring, cherry blossoms and dogtooth violets bloom in Hachigata Castle Park, and as the seasons progress through summer and autumn, various other flowers can be seen. Please come and enjoy both history and a nature walk at the same time.

Arakawa Festival: Beautiful lights reflected on the water
Summer is the season when the Arakawa River shines with color. The Nagatoro Funatama Festival, where boatmen pray to the water god for safety on the water, and the Yoriitamayodo Suitengu Festival, where the water god and Suitengu Shrine are worshipped, are held in August. At the former, lanterns are floated down the Arakawa River, and boats decorated with lanterns travel back and forth on the water, while at the latter, boat floats decorated with paper lanterns float down the Arakawa River. We recommend visiting in the summer to see these fantastical festivals.
