Abstract
The sensory-cognitive characteristics underlying Miyazawa Kenjiʼs literary works often include eidetic images,synesthesia, and fantasy-proneness. This report aimed to examine Kenji's sensory-cognitive characteristics, based on the findings in our studies that eidetic images, synesthesia, and fantasy-proneness could share a common neural and psychosomatic basis. Miyazawa Kenji could be a typical hyperphantasia（Zeman, 2015）, that is, a person with peculiar imagination according to recent research in cognitive psychology and brain science regarding imaginative abilities.
