Visual Navigation Simulator

Equipped with a 360° horizontal view and a lower field of view, this is one of the largest full mission bridge simulators in Japan, and is used extensively for various consulting work, including the study of navigation safety measures. The 360° horizontal view guarantees a natural perspective no matter where on the bridge our viewpoint is. The lower view allows you to view the quay below, enabling a natural grasp of positional relationships between the quay and the vessel.
