Recently, Linda, Fred, Terrance and I made the trek up to the base of Mount Fuji to see the Fuji Yoshida Fire Festival. This festival marks the closing of the hiking trails for Fuji-san. The carrying of the mikoshi through town along with the noise is said to try to appease the goddess of Mt. Fuji so that the mountain will not erupt. Fires are lit from the center of the city all the way to Sengen-Jinja in order to impress the goddess.
You can read more about the Fuji Yoshida Fire Festival by reading on other sites. You can see the festival by watching this video. Enjoy!
