Description

This special edition Hobonichi Techo Weeks planner is a collaboration with the long-running and internationally loved mystery manga series Detective Conan, serialized in Weekly Shonen Sunday.

The “Memorial Conan” edition celebrates the series’ milestone with a cover illustration originally created to commemorate the publication of the 100th volume of the manga. Printed on a canvas-textured material, the cover gathers Conan and many key characters in formal attire, including Conan’s iconic bow tie, making it a collectible design for fans.

The cover is slightly firm yet flexible, typical of Hobonichi’s durable Weeks format. The spine features the English version of Conan’s famous line, “There is only one truth!”, stamped in silver foil so that it shines even when placed on a bookshelf. The back cover features a special collaboration logo between Detective Conan and Hobonichi, stamped in red foil against a white background.

Inside, the planner becomes even more special. Over 300 original illustrations from the manga appear throughout the pages, allowing users to enjoy scenes, characters, tricks, and memorable quotes every day. Opening the cover reveals an illustration of Conan leaning against Café Poirot’s signboard, and two bookmarks in blue and red reference Conan’s jacket and bow tie colors.

An exclusive Detective Conan-themed pencil board is also included, inspired by Conan’s famous tranquilizer watch. A transparent window allows users to see through it, and the board features 1 mm measurement markings so it can also function as a ruler. A “TODAY” tab helps mark the current page, functioning as both bookmark and index. Sound effects such as “pipipipi…” and “pashu!” printed on the board recreate scenes where Conan aims at his targets.

The weekly pages place original manga illustrations across every spread, often matching seasonal events and daily life, allowing users to encounter both character quotes and words selected by the original creator, Gosho Aoyama.

Monthly calendars covering March 2026 through April 2027 spotlight different characters each month. From Conan in March to Ran Mouri in April and many others thereafter, expressions selected from over 100 manga volumes appear throughout the year.

Bonus pages at the back include exclusive content inspired by manga episodes and illustrations, along with custom versions of standard Hobonichi pages and seven unique features available only in this edition. The memo pages are also decorated with character-themed designs.

Inside the back cover, Conan appears again, watching from the window of the Mouri Detective Agency. The planner also includes a reusable clear pocket sticker that can be attached anywhere inside the notebook to store cards or small documents.

This edition combines Hobonichi’s famous usability with the world of Detective Conan, making it both a practical planner and a collectible item for fans.
