北小弓城跡

Gazing across the centuries-old landscape, we find ourselves at the enigmatic Kitakoyumi (Nama) Jōato, also known as the North Oyumi Castle Ruins. This site, shrouded in the mists of time, holds the key to understanding the complex history of the Oyumi area. Kitakoyumi Jōato was once a thriving castle, a testament to the power and influence of the Hara clan. In 1517, the castle was seized by Hōjō Ujitsuna, a powerful warlord. Ujitsuna renamed the castle “Koyumi Palace.” This marked a turning point in the history of Kitakoyumi Jōato. After Ujitsuna’s death in the First Battle of Kokufudai in 1538, the Hara clan reclaimed their ancestral home. They then built a new castle to the north. Recent research has revealed a fascinating twist in the tale of Kitakoyumi Jōato. It seems that two castles coexisted in the area during the Muromachi period. This discovery suggests that the history of Kitakoyumi Jōato is even more intricate than previously thought. The ruins we see today, primarily earthworks and remnants of moats, offer a glimpse into the past. These remnants whisper tales of battles fought, alliances forged, and the rise and fall of powerful clans. Kitakoyumi Jōato stands as a silent witness to the passage of time, a reminder of the rich history embedded in the landscape of Chiba. The site now serves as a peaceful cemetery, its serene atmosphere a stark contrast to its tumultuous past. While exploring, keep in mind access is limited. Parking nearby and walking is recommended. The narrow paths and historic significance make a leisurely stroll the best way to experience Kitakoyumi Jōato.
