In this paper we aim to detect some as- pects of adjectival meanings. Concepts of adjectives are distributed by SOM (Self- Organizing map) whose feature vectors are calculated by MI (Mutual Informa- tion). For the SOM obtained, we make tight clusters from map nodes, calculated by cosine. In addition, the number of tight clusters obtained by cosine was in- creased using map nodes and Japanese thesaurus. As a result, the number of ex- tended clusters of concepts was 149 clus- ters. From the map, we found 8 adjectival clusters in super-ordinate level and some tendencies of similar and dissimilar clus- ters.
