Diane's Tsuda Atsuhiro Releases First Book 'Tsuda Diary', Written Daily for a Year!

Atsuhiro Tsuda, a member of the popular comedy duo Diane, has released his long-awaited first book, 'Tsuda Diary,' through Shinchosha on his 50th birthday, May 27, 2026. The book is a compilation of daily entries written by Tsuda throughout the eventful year of 2025. From his hidden motives and complaints to his joys and sorrows, Tsuda's raw emotions and human nature are on full display, making this book a 'miracle' in the Reiwa era.

(Details regarding the magazine 'Nami' cover, the book's design, and the writing process are included.)

Tsuda began writing the diary after a fortune-teller suggested in late 2024 that a yellow notebook would bring him good luck. He purchased a leather notebook from Hermes and wrote in it every single day of 2025. The book captures his daily life, including arguments with his wife, work struggles, and family time, offering a surprisingly literary look at his life in an age obsessed with time performance.
