It is impossible to discuss Kenzaburo Oe's literary works without mentioning the life with his disabled son. Because Oe's life and literature was deeply affected by his son. 『a Personal Matter』(1964) and 『Rouse Up, O Young Men of the New Age!』(1983) will be the representative works that describe the life with the disabled son. In this paper, I discussed about the relationship and bond between father and son in Oe's novels. It revealed that the close tie between father and son in 『a Personal Matter』is expressed through visual images like the similarity in appearance and habit. On the other hand, the relationship between father and son was tightened by the imagination based on the feeling of guilt or a sense of responsibility as a farther in『Rouse Up, O Young Men of the New Age!』. In addition, I'd like to point out that the relationship between farther and son exceeded the real world and was expanded in the world of soul and rebirth. As the background of the expansion, it is thought that Oe's strong desire for coexistence with his son through rebirth.
