Obunsha Launches New Eiken Exam Preparation Series with AI Grading Feature

Launch of the New Series of Eiken Exam Preparation Books

On September 7, 2026, Obunsha Publishing Co., Ltd., headquartered in Shinjuku, Tokyo, announced the launch of its latest series of Eiken exam preparation books titled "2026-2027 Eiken Exam Last-Minute Prep: Collection of Three Past Exams." This series includes six different levels tailored for various test takers: Pre-1 Level, 2 Level, Pre-2 Level, 3 Level, 4 Level, and 5 Level.

This publication is intended for students who are looking for efficient ways to prepare for the Eiken exams just before the test date. The series contains three past exam papers along with detailed explanations, making it an invaluable resource for those wishing to familiarize themselves with the exam format and question types.

Innovative Features of the Series

Audio Integration

Each book in the series is compatible with Obunsha's official listening app "Eigo no Tomo" allowing users to easily access audio playback. Additionally, audio files can be downloaded from a special website, providing added flexibility for auditory learners.

AI Grading Experience

A key feature of the series is the opportunity to test the "Writing AI Grading" function available in the "Manabi no Tomo" app. This feature offers an AI-based evaluation focusing specifically on aspects of the Eiken exam, providing helpful feedback on vocabulary, grammar, and recommendations for essential improvements needed to enhance writing scores. It can be used to experience the grading process of various levels including Pre-1, 2, Pre-2, and 3 Levels.

Note: The AI grading feature has not been validated or endorsed by the Eiken Foundation of Japan and users are encouraged to review the feedback at their discretion.

Simulation of CBT Test Format

The series also offers a CBT (Computer-Based Testing) experience that closely resembles the Eiken S-CBT format. This allows users to familiarize themselves with the computer-based testing environment, although it is important to note that the questions included are from the traditional Eiken exam.

Comprehensive Audio Access

Every book provides complete audio resources for listening and speaking test preparation. Users can conveniently access this content via the app or downloadable files.
