Generally, "KOKORO" written by Natsume Souseki has been studied as a piece of psychological or romantic literature since it was written. However, this thesis examines "KOKORO" as a novel reflecting the Meiji period. More concentration is placed on the importance of sacrificial suicide practiced in the Meiji period. 'Chichi(father)' of narrator symbolizes the general public under imperialism, and 'Sensei(teacher)' and 'K' represent the educated class. In conclusion, the analysis shows that 'the spirit of Meiji' has double meanings. The death of 'Chichi' shows a devotion to nationalism, where as the death of 'Sensei' and 'K' shows suicides sacrificed for the death of the democratic spirit of Meiji.
