N-value is treated as a key record to estimate some engineering properties in many districts. However, trends in regions covered by the volcanic soils are different from data taken in areas covered by the non-volcanic soils. This discrepancy from the standard trend derived from the non-volcanic soil is defined as the index of the specialty of soils. Hence the discrepancy level should be recognized and revealed in order to use the N-value of local soils as a key record. Kumamoto district is broadly covered by Kuroboku, Akaboku, Haido, Yona and the Aso 4 pyroclastic flow. In this report, the discrepancy level is presented in the some phases.
