Volume 3, No. 2.

This issue was originally scheduled for publication on March 31, 2026. Due to JSBE’s recent transition of DOI registration and publication workflow to J-STAGE, the related administrative and technical procedures took longer than initially expected, resulting in a delay in the release of this issue. We sincerely apologize to our authors, reviewers, and readers for this delay.

This postponement applies only to the publication of the current issue and does not indicate any change to JSBE’s publication cycle or frequency. Following the completion of the DOI transition, subsequent issues will continue to be published according to the journal’s established schedule.
