The Navy Port Monument indicates the range of ports managed by the Navy from Sarushima to Natsushima Island ("Natsushima").
It was rebuilt to a stone pillar in 1883 with an andesitic prism (initially wooden) having a side of about 30 cm.
It is broken into two and when it is connected together, it will be about 3m tall.
