Let's skiing!
Three years ago, I was an instructor.
I worked at two ski schools.
Both schools are good school. Especially, Kaiwa ski school has variety lessons.
Mr.Kaiwa was an olympics racer.
1. Kaiwa ski school 
2. Tsurui ski school 
I introduce my favorite ski area.
That is Yomase ski area. Yomase is a home slope of Kaiwa ski school.
The slope condition of Yomase is good. I recommend to go there at least one time.
