In a remarkable achievement for the educational publishing house Obunsha, based in Shinjuku, Tokyo, they have announced that their web service "Eiken Kakomon for Examinees" has surpassed 20,000 registered users as of July 23, 2025, just 11 months after its launch in September 2024. This platform provides past exam questions specifically tailored for the Eiken, or Practical English Proficiency Test, covering levels from pre-1st grade to 3rd grade.

A Revolutionary Learning Tool

The Eiken Kakomon website allows users to engage with high-quality exam preparation materials conveniently through their smartphones, tablets, and PCs. The service boasts a variety of features designed to support students in their preparation for the Eiken exams, making study both efficient and flexible.

Key Features and User Feedback

Among the offerings, the most highly rated feature is the 'Past Questions (1st Exam Preparation)' tool, which garnered a satisfaction rate of 46.6%. This was followed by the 'AI Writing Assessment (Beta)' at 21.2%. Users appreciate the ability to study on the go—whether on their commute or even relaxing at home—and the tailored learning opportunities this platform facilitates.

In a survey conducted from May 30 to June 30, 2025, among users of Eiken Kakomon, feedback was overwhelmingly positive. One working professional noted, "I was able to solve past questions on the train and even while lying in bed. I could focus specifically on the questions I got wrong." A high school student echoed this sentiment, emphasizing the platform's higher accuracy and quality compared to other apps.

Another high school user expressed satisfaction with the visible progress tracking, while others appreciated the convenience of simulating the second exam using their smartphones. The AI-assisted writing evaluation was highlighted for its clarity in showing students how to improve their writing skills.
