Powerful Support for ICT-Based Career Guidance! Obunsha Launches Free 'PDF Viewer' for Teachers at Schools Adopting the 'Keisetsu Jidai' University Entrance Exam Magazine Series — Electronic Versions of Monthly and Special Issues to Launch Simultaneously Starting in Fiscal Year 2026

Educational publisher Obunsha Co., Ltd. (Shinjuku-ku, Tokyo; Representative Director and President: Hideki Kumekawa) is launching a new complimentary 'PDF Viewer' service that allows teachers at schools that adopt the 'Keisetsu Jidai' university entrance exam magazine series—which boasts over 90 years of history—to view the magazine's pages for free. Furthermore, starting in fiscal year 2026, both the monthly 'Keisetsu Jidai' and the 'Keisetsu Jidai Special Issue' will be available for purchase as e-books.

[Exclusive to Adopting Schools] Free 'PDF Viewer' to Support High School Teachers' Career Guidance In this push toward ICT integration, we have focused particularly on expanding career guidance support for high school teachers. Responding to strong requests from over 80% of teachers at schools that adopt the 'Keisetsu Jidai' series—who expressed a desire to 'utilize the content more conveniently in a digital environment'—we are providing a dedicated PDF viewer as a complimentary service on our high school portal site, 'Obunsha Passnavi for School,' allowing teachers to view the magazine pages directly in their browsers.

Three Benefits of This PDF Viewer for High Schools:

① Access to the detailed and vast information of 'Keisetsu Jidai' from the staff room or teachers' PCs Previously, 'Keisetsu Jidai' was typically kept in career guidance offices or classroom bookshelves. With this free PDF viewer, teachers can now access the latest issues from their own PCs in the staff room. Because it is a browser-based viewer that requires no installation, the magazine can be deployed to teacher PCs without incurring additional costs.

② Pinpoint access to necessary information via text search To reduce the time teachers spend searching for information in thick magazines, the PDF viewer includes a 'text search function.' When teachers need help with career guidance or require specific university information, they can perform pinpoint searches using relevant keywords within the magazine's content, enabling smoother and more accurate career guidance tailored to each student.

③ Provision of PDF data for creating and distributing career materials Furthermore, selected article content from each issue of the 'Keisetsu Jidai' series that is suitable for career guidance will be provided in a downloadable PDF format. Teachers can use this content directly for career materials or for distribution to students and parents without any extra effort.

* Use of this service requires the school to purchase the physical product. * To use the service, please register an account on the high school portal site 'Obunsha Passnavi for School' and verify your school enrollment using an authentication code.

Monthly Magazine Finally Available as an E-book! Supporting Students and Teachers with a Hybrid of Print and Digital The e-book version of the 'Keisetsu Jidai Special Issue,' which launched in 2025, was well-received by many readers, including students, for the benefit of 'not having to carry around thick magazines.' Following this positive response, we have decided to expand the monthly 'Keisetsu Jidai' magazine into a hybrid format of print and digital starting in fiscal year 2026.

'Maintaining the reliability of the information while making it more accessible.' By enabling users to easily view the magazine on smartphones and tablet devices anytime and anywhere, we are realizing highly convenient information delivery that is not restricted by location.

By fusing the editorial expertise of the traditional 'Keisetsu Jidai' with digital technology, Obunsha will continue to strongly promote DX (Digital Transformation) in the educational field by combining the comprehensive overview of print media with the mobility of digital tools.
