We would like to express our gratitude for your contributions to our official scientific journals, The Journal of Toxicological Sciences and Fundamental Toxicological Sciences.

We have decided to make both journals open access in order to internationalize them and expand their reach to a broader audience. Articles will be published under the Creative Commons license with the highest degree of freedom, CC BY (4.0). As a result of this change, article copyright will belong to the authors, and secondary use, including copying, distribution, display, storage, modification, and commercial use, can be carried out without the relevant society’s permission.

The new Instructions for Authors will be published on the journal websites in advance. These new submission guidelines 
will apply to papers submitted on or after June 1, 2025 (Japan time). Please note that the previous Instructions for Authors will apply to papers submitted until May 31, 2025 (Japan time).

We hope that this change will encourage you to submit more of your excellent papers to The Journal of Toxicological Sciences and Fundamental Toxicological Sciences.
