This diary combines the practicality of a planner with the timeless charm of a beautifully crafted book—something to treasure long after the year has ended.

The cover is wrapped in a warm, textured cloth material and features an endearing cat-themed design. Built with a durable book-style construction, it is designed to be kept and enjoyed as a cherished keepsake even after it has been filled.

The theme of this edition is "Life with a Black Cat." Illustrator Sayo Koizumi brings the pages to life with soft, sketch-like illustrations that capture the quiet charm and personality of a beloved black cat. A unique illustration appears throughout the diary, creating a warm and inviting experience from cover to cover.

In addition to its planning pages, the diary includes a variety of supplementary pages designed for personal record-keeping and reflection. Special gallery pages feature original artwork created to complement the themes of the monthly sections.

The gallery pages also provide generous writing space, making them ideal for preserving treasured memories, recording a child's growth, or documenting other meaningful moments throughout the year.

The gift list page features a playful design with a black cat peeking out from the illustrations, adding a touch of charm and whimsy. (The memory pages use the same design as the 2026 edition.)
