志摩城

Shima Castle is a Japanese fortress in Chiba Prefecture featuring traditional wooden structures and stone foundations positioned on elevated terrain. The site shows multiple defensive rings strategically arranged around its highest point.

The fortress was built during the Sengoku period as a defensive outpost controlling eastern approaches to the Kanto region. It played an important role in military control over this strategically valuable area.

The castle reflects feudal military architecture through its defensive layout and strategic positioning on the terrain. Today, visitors can observe how natural landscape features were incorporated into the fortress design.

The castle grounds are accessible through marked paths leading to observation points with views of the surrounding landscape. Wearing comfortable shoes is helpful since the terrain is uneven and some areas rise steeply.

The fortress used natural terrain features such as hills and slopes as an integral part of its defensive system. This shows how Japanese builders turned the landscape itself into a weapon.
