'Tsuda Nikki' is a diary that Tsuda kept every single day in the "Goigoisu" year of 2025. His ulterior motives, complaints, joys, and sorrows...

Tsuda is active in a wide range of fields, including television, radio, theater, YouTube, and even dramas. His remark, "Please give me long sleeves," made during the popular segment "Detective Tsuda" on "Wednesday Downtown," was nominated for the "New Words/Buzzwords Award 2025," gaining popularity that can now be called a social phenomenon.

【What was the inspiration for writing 'Tsuda Nikki'?】
Tsuda was told by a fortune teller at the end of 2024 that his luck would improve if he bought a yellow-covered notebook. He bought a yellow leather notebook from Hermes and decided to keep a diary for the entire year of 2025. Fights with his wife, drinking with Chidori Daigo, sauna with Rice Sekimachi, shopping with his son and daughter, radio not going well, tough shoots for Detective Tsuda... his daily life is candidly and honestly recorded.
In an era where efficiency is everything, 'Tsuda Nikki,' which he diligently continued to write by hand every day, has become a book that even feels literary, transcending the boundaries of a "comedian's book"!

【Is Tsuda a new star in the "Diary Community"!?】
The "Diary Community" is currently booming, especially among Generation Z. The "Diary Community," as the name suggests, refers to "people who write diaries." Traditionally, diaries were kept private and not shown to others, but Gen Z's diaries are the opposite. The mainstream style is to intentionally share daily events on social media. It may not be long before Tsuda, who is turning 50, becomes a new star in this "Diary Community"...!
