Hasuike Castle

Hasuike Castle is a mountain fortress on Shikoku island built on a strategically advantageous hillside. The site consisted of multiple defensive rings that took advantage of natural terrain features, with foundation stones still visible today.

The fortress was built during Japan's Sengoku period, when regional lords constructed fortifications to defend their lands during warring times. It reflects the military needs of that era and was eventually abandoned.

The castle was built following traditional Japanese defensive design, with concentric stone rings that remain visible today. Visitors can observe how the innermost and outer areas were separated by different elevation levels and fortifications.

The site is best explored by climbing the hill and following the pathways that circle the former castle grounds. Comfortable shoes are recommended since the terrain is uneven and some sections have steep inclines.

The fortress location allowed inhabitants to monitor multiple mountain passes and observe movement across large distances. This made it a key position in the network of regional control during the conflicts of its time.
