The Function of Aizuchi by Native Japanese Speakers on the Miku Real Japanese YouTube Channel

Abstract

This study aims to analyse the proficiency, specifically the usage patterns, of aizuchi functions among native Japanese-speaking women. Aizuchi, defined as the brief conversational responses signalling understanding, agreement, or engagement in Japanese dialogue, forms the core of this investigation. Utilizing qualitative descriptive analysis, the research examined transcribed conversation data sourced from a specific YouTube video titled “Japanese Conversation about LOVE / Relationship” on the 'Miku Real Japanese' channel, published January 3, 2023, featuring a dialogue between channel owner Miku and guest Sayuri. The study underscores the critical importance of aizuchi in Japanese communication. Analysis revealed seven distinct functional categories: the sign of listening (Kiite iru to iu shingou) was most frequent with 32 utterances, followed by the sign of understanding (Rikaishiteiru to iu shingou) with 14 utterances, the sign of agreement (Doi no Shingou) with 11 utterances, the sign of emotional expression (Kanjou no Shingou) with 9 utterances, the sign of adding/correcting/requesting information (Jyouhou wo tsuika, teisei, youkyuu no shingou) with 4 utterances, the sign of filling pauses (Ma wo motaseru Shingou) with 2 utterances, and the sign of denial (Hitei no Shingou) appearing just once. Remarkably, with a total of 73 aizuchi utterances occurring within just 8 minutes of bidirectional conversation, the video demonstrates an exceptionally high frequency of these conversational cues. Consequently, the study suggests future research should delve deeper into aizuchi, potentially focusing on speakers' Japanese language proficiency backgrounds or examining conversations across specific age ranges, such as between children and adolescents, adolescents and adults, or adults and the elderly.
