The History of Satomi Park
Satomi Park is a municipal park of Ichikawa City having 82 hectors of
land on the western edge of Shimousa Plateau called Konodai that faces
to Edogawa River
The area where Satomi Park is in has several old mounds and there was the
provincial office and Kokubunji Temple
was built near it, so Konodai was the political and cultural center of
in Classical Ages. Moreover, before Ieyasu Tokugawa moved Tonegawa River
to east in early Edo period, there had spread low wet lands overgrown with
cogon on between Edogawa and Sumidagawa River since Tonegawa
and Watarasegawa river had carried their whole water to Edo (Tokyo) Bay,
so Konadai was the strategically important area to take Kanto Region and
to protect Edo.
According to Gikeiki (the biography of Yoshitsune Minamoto) and Edo Meisho Zue
, there was Ichikawajo Castle built in anywhere around Konodai in Kamakura period
. In Sengoku period
, Dokan Ota built Konodaijo Castle
and the Battles of Konodai
had happened twice there in 1538 and 1564, as the result of the battle,
gained the power to control the area.
After the Siege of Odawara in 1590, the Hojo Clan was ruined and Ieyasu Tokugawa
moved to Edojo Castle to rule Kanto Region, and he destroyed Konodaijo
Castle since it could command the panoramic view of Edo and his castle.
In Edo Period, Edogawa River brought millions of goods from north Kanto
and Tohoku Region (northern provinces) by ships since the river connects
to Tonegawa River
, so the towns along the river had been very flourished. The views of Konadai
area at that time was introduced in Edo Meisho Zue and in Meisho Edo Hyakkei
painted by Hiroshige Utagawa
Fromr Meiji Restoration to the end of WWII, the area around Konodai was flourished as a military town and an amusement park named Hakkeien was built in the land now Satomi Park is.
In 1959, Satomi Park was opened as a municipal park of Ichikawa City to preserve the history and culture since there was Konodaijo Castle in the Warring State Period.
The Remains of Konodaijo Castle
While walking in the woods in the northern area of Satomi Park, many large
stones as large as ruggby balls are scattered on the bottom of the valley
that might be a moat. And there are several remains of fort made with piled
soil in the woods. They are the remains of Konodaijo Catle built in Sengoku
Period and it was also called Ichikawajo Castle. Anyway, it is said that
Ichikawajo Castle might be in the area Mamasan Guhoji Temple
According to Edo Meisho Zue, first Kofu Family, a branch family of Chiba Family
, built their castle at Konodai, but it was abandoned. In 1479, Dokan Ota
who was a popular daimyo in Muromachi Period
famous for building Edojo
and Kawagoejo Castle built Konodaijo Castle.
There is the highest point of Ichikawa City in the remains of the castle,
the observatory in the western part of Satomi Park commands the panoramic
views of Tokyo even now. Edo Meisho Zue said that poeple could see Edojo
Castle from the tea room at Mamasan Guhoji Temple 1 kilo-meter southeast
of it. Thus, it could command most part of Kasai and Tokatsu county (both
sides of Edogawa River) in Shimousa
. Moreover, Konodai area had been good land to protect it since there had
been low wet lands in the west where Tonegawa
, Watarase and Arakawa River flowing through and Mama no Irie (Mama Cove)
in the south before Ieyas Tokugawa
moved Tonegawa River to east.
After the Siege of Odawara in 1590, Ieyasu Tokugawa moved to Edojo Castle to rule Kanto Region, and he destroyed Konodaijo Castle since it could command his castle.
In Sengoku Period
, the battles between Satomi Clan
and Hojo Clan
happened twice in the area around Satomi Park. There are many remains
and stories introduced in neighbor cities of Ichikawa such as Matsudo,
Edogawa and Katsushika.
The First Battle of Konodai in 1538
The first battle of Konodai was happened in October 1538 by Oyumi Kubo
Yoshiaki Ashikaga in Kazusa
to try to attack Hojo Clan in Odawara to gain the authority to control
Kanto Region since the Hojo supported his rival Koga Kubo
Haruuji Ashikaga. Yoshiaki and his supporters Satomi in Awa, Sakai and
Takeda in Kazusa assembled and pitched camp at Konodaijo Castle
As soon as Ujitsuna Hojo, the head of the Hojo, got the information, he
and his son Ujiyasu went to Edojo Castle
and go to Konodai to fight against Yoshiaki and his supporters.
In the early morning of October 7th, the battle between them happened, Ujitsuna reached at Edogawa River, then he divided his arms into three groups, and he took the one group and attacked the Oyumi Kubo's arms at Sagamidai Hill then he went to the south, finally he took Konodaijo Castle, so the Hojo won the first battle of Konodai. As the result of the battles, Yoshiaki Ashikaga, his son Yoshizumi, his brother Motoyori, and his chief retainer Shosen Henmi and 140 samurai worriers died at the battle, so Oyumi Kubo Family was ruined. However, the Satomi destroyed Oyumijo Castle and escaped to his homeland Awa province.
After the battle of Konodai in 1538, Koga Kubo Haruuji Ashikaga gained the authority as the Kanto Kubo and he gave his reward Ujitsuna Hojo with the position to control samurai worriers in Kanto Region called Kanto Kanrei and Ujitsuna became a maternal relative. Therefore, the Chiba
in Shimousa, the Takeda in Kazusa and some daimyos in the Kanto followed the Hojo and the Hojo's influence in the Kanto increased. By the way, the Satomi gained Oyumi Kubo's castles such as Otakijo and Kururijo Castle and also increased their power in Kazusa province.
The Second Battle of Konodai in 1564
After 26 years passed, the First Battle of Konodai had ended, the Second
Battle of Kondai broke out in January 1564. Satomi Clan in Awa cooperated
with Uesugi Clan in Echigo to stop the influence of Hojo Clan in Odawara
to Boso Peninsula. Yoshihiro Satomi, the head of Satomi Family, tempted
Sukemasa Ota in Iwatsuki and Yasusuke Ota in Edo
and they took up the position at Konodaijo Castle to attack the Hojo from
both north and south side.
Hearing from Chiba Clan, Ujiyasu Hojo
, the head of Hojo Family knew the Satomi's action, then he and his son
Ujimasa took 20,000 samurai worriers to Konodai to fight against them.
In January 7th, the Hojo reached at a shore of Edogawa River.
First, Tsunakage Toyama and Masaie Tominaga opened hostilities, and they crossed a ford of Edogawa River to attack the Satomi's, but Tsunakage and Masaie died in the battle. The Hojo retreated once. The Satomi and the Ota pleased at the victory, then they gave alcohol to their soldiers at night. When they were off their guard, the Hojo made a surprise attack on them before daylight in January 8th. The arms of the Satomi and the Ota fell into great confusion, the Satomi escaped to Awa and the Ota fled in disorderly retreat. Finally, the Hojo won the great victory.
After the Second Battle of Konodai, Hojo Clan gained the power to rule
Edo from Yasusuke Ota, and their influences extended not only Shimousa
but also Kazusa province. The Hojo took Edo as the strategic foothold to
invade the northern Kanto region.
