Air travel from Sapporo New Chitose Airport to Narita Airport. Luckily, I witnessed the Brocken phenomenon. Brocken’s phenomenon is a phenomenon in which the light from the sun behind is scattered by clouds and fog particles on the shadow side and appears as a ring of light like a rainbow. It is famous as a weather phenomenon in mountains, but it can be seen from aircraft. The name is said to come from the fact that it was often seen on Mt. Brocken, the highest mountain in Germany. It is also known as the specter of Brocken.In Japan, it is called goraigo. I was fascinated by this strange sight for a while.
On the way from Matsuyama to Fukuoka, I saw the Suo oshima from the air. Since ancient times, it has been an important port for maritime traffic. In the Seto Inland Sea, it is very large after Awajishima and Shodoshima.
