The purpose of this study is to develop improvement systems for the living environment by Residents' Associations through preparing the "Living Environment Maps". As the second stage of this study, this paper examined the supporting methods for living environment measurements with residents' participations based on the whole process of the field measurements for noise level and NO_2 concentration, which residents actually participated in at the case studies with 3 Residents' Associations. Researchers' supports for explanations and coaches for using noise level meters and capsules for NO_2 capture are effective for promoting residents' participations to the measurements.
