It is my great pleasure to announce the strengthening of our editorial board. Since I assumed the position of Editor-in-Chief following Professor Masayasu Mimura, the number of submissions and published papers has substantially increased, and four editors are too few to deal with the upsurge in submissions. All the editors and the members of the publication committee have felt the urgent need of adding new forces. We are now introducing a new editorial board as is listed on the inside front cover. On behalf of the editors I would like to express our commitment to further expansion and improvement of the Japan Journal of Industrial and Applied Mathematics.
