With the conclusion of Volume 30, Professor Mamoru Saito will be retiring from the co-editorship of JEAL in anticipation of his upcoming retirement from active duties as Professor and Dean of the Faculty of Global Liberal Studies at Nanzan University in early 2022. Professor Daiko Takahashi of Tohoku University has accepted our invitation to succeed him as our new Co-Editor. They have been collaborating as Co-Editors for the past two years (Volumes 29 and 30). We would like to express our most sincere gratitude to Professor Saito for his valuable, critical contributions to JEAL over the past 26 years. The growth and development of JEAL to this date would not have been possible without his generous guidance, vision, and dedication. We wish him well and hope to continue to rely on his advice in other ways. We also welcome Professor Takahashi and look forward to continuing our collaboration with him in the years to come.
