The southern part of the Saganoseki Peninsula faces the Pacific Ocean and offers a relatively wide view of the sea. On the southern side of the peninsula, the minus magnitude star Canopus can be seen under the right conditions.
The conditions are a clear day, with a clear horizon and no clouds.

Canopus shines brightly at high altitudes in the southern hemisphere, but is rarely seen in the northern hemisphere.
In Japan, there are few opportunities to see Canopus, which is why legend has it that if you can see it, you will live longer.

Japanese people believe that if you can see Canopus, you will live longer and have more energy.
