Thank you for viewing. There are markings in the Japanese history section with a highlighter and mechanical pencil only. There are no markings in the world history section. Even for those who are taking Japanese history, some of the questions appear online, so it's also recommended for those who want to know the answers and the level of difficulty. I am also selling many red books for Rikkyo University's Japanese language and other reference books. I welcome bulk purchases, so please feel free to contact me.
