Kakegawa-jo Castle / The Short Summary Of Kakegawajo Castle
          Kakegawajo Castle was bulit by Asahina Clan by order from their master
          Imagawa Clan, the military governor of Suruga Province in order to expand
          to Totomi Province in early Sengoku Period (the warring States Period),
          it was the strategically important castle to protect and invade to Totomi
          Province. So 
Kakegawa was in Totomi Province (west part of 
Shizuoka Prefecture) and it was near the boundary between Suruga (central part of Shzuoka
          Prefecture) and Totomi. This was the beginning of the history of Kakegawa
          Castle. Kakegawa Castle we could see now rebuilt by Kazutoyo Yamanouchi
          in Azuchi-Momoyama Period.
 Kakegawa was the strategic center of the eastern Totomi Province to seize Tokaido road in Sengoku Period, then conflicts to gain the castle oftne occured among the sengoku daimyos.
            Yoshitada Imagawa commanded Yashuhiro Asahina to built Kakegawa Castle
            to gain Totomi Province in the middle of Muromachi Period, and the Asahina
            Clan stayed to protect it as the jodai (castle keeper), so his son Yasuyoshi
            and his grandchild Yasutomo succeeded the position to keep it. In 1497,
            Ujichika Imagawa and Soun Hojo invaded to Totomi Province and conqured.
            Then the Asahina Clan built a new Kakegawajo Castle on Mt.Ryutosan 500
            meter southeast left from the Old Kakegawajo Castle. Imagawa Clan ruled
            Totomi Province and Asahina Clan ruled Kakegawa. Imagawa ruling 2 provinces,
            they tried to expand and they finally gained the power to rule Mikawa province
            in 1549 when Ieyasu Tokugawa who was the 5 years old lord of the province
            was taken as a hostage. Then the Imagawa Clan seized 3 provinces and it
            became the strongest and most influential daimyo in eastern Japan. However,
            the Imagawa Clan lost the Battle of Okehazama in 1560 and Yoshimot Imagawa,
            the head of the family was killed by Nobunaga Oda, the clan soon lost the
            power. Ieyasu Tokugawa, he became a hostage once, but he went back t and
            took back his position in Mikawa Province (eastern part of Aichi Prefecture),
            and he tried to gradually expand his territory to Totomi Province. In 1568,
            Shingen Takeda, the lord of Kai-no-kuni (Yamanashi Prefecture) invaded
            Suruga Province, then Ujitsuna, the son of Yoshimoto escaped to Kakegawa
            Castle, but next year, he opened the castle and gave it to Ieyasu Tokugawa.
            The Tokugawa Clan gained the power to rule Totomi, and he left the castle
            to Ienari Ishikawa and his son Yasumichi Ishikawa to keep. But it was not
            stable, Takeda Clan next to him also tried to expand to Totomi. In 1571,
            Shingen attacked Takatenjinjo Castle on the south of Kakegawa Castle, but
            he could not gain it because of its strong protection. In 1574, Katsuyori
            Takeda, the son of Shingen took over Takatenjinjo Castle. Ieyasu then built
            Yokosuga Castle to regain it. In 1581, Ieyasu succeeded to take back it.
            The Kakegawa Castle was the front line between the Tokugawa and Takeda
            for 10 years, the Ishikawa and the Tokugawa successfully protected the
            castle.
          In 1586, Ieyasu Tokugawa submitted to Hideyoshi Toyotomi who was the Kanpaku
          Dajo-daijin (the supreme minister and chancellor) having the power to rule
          the samurai society,, and he became his vassal. In 1590, Ieyasu moved to
          Edo (
Tokyo), then Kazutoyo Yamanouchi, a vassal of Hideyoshi moved to Kakegawa Caslte
            from Nagahama Castle in Shiga Prefecture. Kazutoyo rebuilt the castle,
            so he built the stone walls, the donjon, otemon gate and other buildings
            with tile-roofs, he also constructed levee in Ooigawa river to prevent
            flood, so he worked hard to keep the castle well. Kakegawa Castle we could
            see now was rebuilt by him at that time. 
          In 1600, Ieyasu won the Battle of Sekigahara and gained the power to control
          Japan. He took back Kakegawa Castle, so Kazutoyo moved to Kochi Prefecture,
          and Sadakatu Matsudaira was given it by Ieyasu. In Edo Period, Kakegawa
          was a strategically very important post town to protect Edo, then Matsudaira,
          Ii, Honda and Ota, daimyos in hereditary vassalage to the Tokugawa, were
          appointed such as the lords of Kakegawa to control. Moreover, Kakegawa
          was connected to Edo by Tokaido road, so the tourist industries were flourished
          with two post towns Kakegawa and Hisaka. However, almost buildings of Kakegawa
          Castle were broken down by Ansei Tokai Jisin (the big earthquake) in 1854.
          Ninomaru Goten palace was only rebuilt in 1861 untile Edo Period (1603~1867)
          ended. In Meiji Era, Kakegawa Castle was abandoned by the Ordiance Abolishing
          Castle in 1871.
          In 1994, the donjon was rebuilt with wood, so Kakegawajo Castle's Tower
          was the first wooden donjon reconstructed, then it has been called the
          best castle in Tokai region. And Kakegawajo Castle was selected one of
          the 100 best castles in Japan in 2004. There ara hundreds of Cherry Trees
          around the castle and many visitors come to see them in spring.

          Taiko Yagura is the tower to store the drum to tell time for residents
          around Kakegawajo Castle in Edo Period. The drum used in the period was
          preserved in the main hall at Kakegawajo Goten (the palace at Kakegawajo
          Castle) and visitors could see it there.

Yonsokumon Gate has a gate with four pillars. It was a kind of a toll gate having a place to watch visitors inside the gate. It was a important gate on the way to the donjon.

The Legend Of Kirifuki Ido Well
There are some legends remained of Kakegawa Castle, the legend of Kirifuki Ido well is one of that.
            When Shingen Takeda and Ieyasu Tokugawa had invaded to his territory, Ujizane
            Imagawa escaped to Kakegawajo Castle that was kept by Yasutomo Asahina.
            While Ieyasu surrounded the castle to overtake it, Kakegawa Castle was
            blanketed in a fog set from a well beside the donjon, then Tokugawa army
            could not attack it. After that, Kakegawajo Castle was called Kumokirijo
            Castle ( a castle wrapped in a fog or a cloud).
 Kirifuki Ido Well exists beside the donjon now.
