Obata Castle Ruins

Overview

Obata Castle Ruins is the site of a flatland castle built during the Sengoku period (Warring States period) in Ibaraki-machi, Higashiibaraki District, Ibaraki Prefecture. Now a well-maintained castle park, visitors can explore the remaining structures, such as stone walls and moats. It's believed that Obata Castle came under the influence of the Edo clan of Mito Castle sometime after the Bunmei era (around 1481). The current castle grounds are believed to have been developed during the Genki-Tensho period (1570s), playing a crucial role as a base for attacking the Ojou clan of Fuchu Castle. Letters from 1585 mention Otsuka Yasaburo and Obata Magonjiro as castle commanders of Obata Castle. Around this time, local lords around the swamp were reportedly mobilized on a rotational basis to strengthen the castle's defenses. In December 1590, due to the power of Toyotomi Hideyoshi, Satake Yoshinobu of Ota Castle (Hitachi-Ota City) seized Mito Castle from the Edo clan, leading to the demise of the Ojou clan of Fuchu Castle. It is believed that Obata Castle also fell at this time. It is said that afterwards, until 1620, it became a directly governed territory of Satake Yoshinobu, managed by his retainer Wada Akitsugu. However, it is believed that Obata Castle concluded its centuries-long historical role around the time of its fall in 1590 or with the relocation of the Satake clan. Obata Castle is a remarkably unusual structure for an earthen castle on level ground, featuring high earthworks and deep moats designed to enable attacks on enemies from the elevated enclosures above. Visitors can walk along the moat paths and experience the castle's structure as it was in its time. Remnants such as the remains of the main enclosure, wells, and watchtowers evoke the atmosphere of the past, making it a must-see spot for history buffs. Obata Castle Ruins is a perfect place for history enthusiasts, as well as for those enjoying a leisurely stroll or hike. With ample parking and restrooms available, visitors can explore with ease.
