This article provides a historical overview of the evolution of learner corpus research (LCR) in Japan, tracing its development from its inception to recent advances in the 2020s. Initially centered on smallscale corpora, primarily in English, the field grew substantially in the 2000s with the emergence of large, systematically compiled corpora, including the NICT Japanese Learner English (JLE) Corpus and the Japanese EFL Learner Corpus (JEFLL). The 2010s brought further diversification through multinational and multilingual corpora, such as the International Corpus Network of Asian Learners of English (ICNALE), and extensive learner corpora for Japanese as a second language, including the International Corpus of Japanese as a Second Language (I-JAS). Methodologically, this period was characterized by greater use of standardized proficiency scales, the incorporation of large-scale data from online sources, and closer integration with second language acquisition (SLA) theories. Japanese LCR continues to mature through longitudinal data and increased attention to underrepresented learner groups and language pairs. More recently, the convergence of learner corpora with generative AI-based tools for annotation, feedback, and assessment has opened a new phase in the field. This article examines how these emerging practices are taking shape in Japan and considers their implications for learner corpus research and corpus-informed language education.

本稿は、日本における学習者コーパス研究(LCR)の発展を、黎明期から2020 年代の最新動 向まで歴史的に概観する。初期には英語を対象とした小規模コーパスが中心であったが、2000 年代にはNICT JLE Corpus やJEFLL Corpus など、大規模かつ体系的なコーパスの構築によっ て研究が大きく進展した。2010 年代には、ICNALE に代表される多国籍・多言語コーパスや、 日本語学習者を対象とするI-JAS などが整備され、対象がさらに広がった。方法論的にも、 標準化された熟達度尺度の活用、オンライン資料に基づく大規模データの導入、第二言語習 得理論との連携が進んだ。現在、日本のLCR は、縦断データや十分に研究されてこなかった 学習者集団・言語への注目を強めながら成熟を続けている。近年では、アノテーション、フ ィードバック、そして、評価に生成AI を活用する実践が学習者コーパスと結びつき、新たな 段階が始まりつつある。本稿は、こうしたLCR 研究の日本における展開を論じ、学習者コー パス研究とコーパスに基づいた言語教育への示唆を検討する。

    The goals of Asia TEFL are to promote scholarship, disseminate information, and facilitate cross-cultural understanding among persons concerned with the teaching and learning of English in Asia. In order to accomplish this, Asia TEFL will pursue the following goals: 1. To link ELT professionals in joint research on issues and concerns regarding English teaching and learning in the Asian context. 2. To publish an academic journal, The Asia TEFL Journal, as an internationally recognized journal in the field of English language teaching. 3. To host conferences and seminars addressing important issues concerning ELT in Asia. 4. To develop proficiency guidelines and assessment methods designed for the needs of the Asian context. 5. To develop programs for Asian learners and teachers of English to build their English language proficiency and cultural understanding and provide them with the skills required to be efficient English teaching professionals.
