All date of Politeness when native Japanese speakers and Uzbek Japanese learners give warnings about prohibited acts

Survey participants of this study fall into three groups: 36 native speakers of Japanese (Jap.), 36 Uzbek speakers who were learning or had learnt Japanese (UJap.), and 36 native speakers of Uzbek (Uzb.). We focused on Jap. and UJap. surveys and also analyzed the Uzb. data as a reference. The Uzb. data were collected and analyzed to investigate the possibility of Uzbek interference with the UJap. data. All participants were university students or alumni. The UJap. participants’ Japanese language level was intermediate (i.e., level between N3 and N2 of Japanese language proficiency).
