Exciting Launch of 'Seasonal Diary'

The world of personal expression through diaries is about to receive a refreshing addition. Published by Tsukihi Co., Ltd., led by managing director Shintaro Uchinum, the literary magazine titled 'Seasonal Diary' is set to make its debut in early December 2025. This unique magazine will focus specifically on journals, capturing the art of diary writing and reading from various perspectives.

In recent years, there has been a notable surge in books dedicated to diaries, encompassing everything from commercially published works to independently crafted zines and little presses. While social media heavily influences how personal experiences are shared, the increasing sophistication of generative AI has blurred the lines of authenticity. Amid this technological evolution, the yearning for genuine human reflections expressed through diaries has intensified.

A Unique Concept

The 'Seasonal Diary' aims to delve deep into the allure of diary writing and reading. It is anticipated to be unprecedented not only in Japan but also globally as a magazine dedicated entirely to the subject of diaries. Each issue will highlight special topics, and the inaugural edition will feature prominent sections titled 'The Joys of Diary Writing' and 'Diaries and Horror'.

One of the standout ongoing features, 'A Week with 25 Authors', will present the diaries of twenty-five diverse writers reflecting on the same week, showcasing the rich variety of voices and experiences that diaries encompass. Contributors include well-known names such as Mariiko Adachi, Ao Ito, Kohei Inose, and many others, each sharing their unique perspectives.

Thematic Highlights of the Inaugural Issue

The special feature, 'The Joys of Diary Writing,' includes captivating dialogues, interviews, and essays. Notably, a conversation between Kazuko Uemoto and Pha discusses practical tips for starting one's expression journey. Meanwhile, insights from Takumi Fukubo and Shoji It reveal how personal narratives can resonate deeply.

The second major special focus, 'Diaries and Horror,' will explore the intersection of these two genres. Featuring a unique dialogue between Tokio Omori and Hiroki Yamamoto, the section investigates why both diaries and horror are currently trending topics, alongside essays from writers like Kenichi Shokumi.

Additional Features

The magazine will include a roundtable discussion between Inteige Inc. and Tsukihi Co., discussing the creation of a diary tracking platform and will invite readers to contribute their own experiences as well. The upcoming issue will tease the theme 'Diary Struggles and Diaries & Plants'.

Publication Details

The first issue of 'Seasonal Diary' will be approximately 350 pages long, published in A5 format. It is scheduled to hit the shelves on December 8, 2025, buoyed by the excitement surrounding the seventh 'Diary Festival' and will be available for pre-sale online via Value Books. The retail price is set at 1,980 yen plus tax, with an ISBN of 978-4-9913584-1-8 C 0095. Anticipation is building within the community, as this magazine promises to revolutionize the way diaries are perceived in contemporary culture.
