Senior High School Level
Senior High Schoolers across Fukushima and Japan use a range of textbooks and resources. Many of them may be made to specifically suit the needs of the class, or the textbook material, but nevertheless there are many useful resources available. For lower ability students and first year high schoolers, content made for junior high school is also easily adaptable.
