Abstract
This study measured learners' understanding of contexts in which native Japanese speakers do not use 'Noda', using multiple-choice questions. Using a multiple-choice questionnaire, we measured learners' comprehension in scenarios where "Noda" is not typically used. Additionally, role-play activities were incorporated to investigate the alignment between learners' comprehension and production. Specifically, the study focused on three distinct situations: maintaining the interlocutor's perception, correcting the interlocutor's perception, and responding to the interlocutor's WH-questions. The results indicate the effectiveness of teaching intermediate-level learners to comprehend contexts in which "Noda" is not used. Furthermore, the study suggests the utility of creating an environment similar to being in Japan for enhancing this understanding.
