Get Ready for a Detective’s Daily Planner: ‘Meitantei Conan’ x Hobonichi Techo Collaboration!
Fans of classic detective work, rejoice! ‘Meitantei Conan’ is teaming up with the beloved Hobonichi Techo for a special line of collaboration planners and stationery, set to launch as part of the ‘Hobonichi Techo 2026 spring’ April-start edition. The goods will go on sale starting Sunday, February 1st, 2026, on the Hobonichi Online Store and other retailers.
For the uninitiated, ‘Meitantei Conan’ is the legendary detective manga by Aoyama Goushou that has been serialized in Weekly Shounen Sunday since 1994. It follows the story of high school detective Kudou Shinichi, who is transformed into a child by a mysterious organization in black and continues to solve tough cases under the alias Edogawa Conan.
The TV anime adaptation began airing in 1996 and has continued for over 25 years, surpassing 1100 episodes. The 29th movie, ‘Highway no Tenshi’ (which can be translated as ‘The Fallen Angel on the Highway’), is scheduled for release on April 10th, 2026.
This collaboration brings fans a special edition weeks (weekly planner) packed with over 300 original illustrations. The lineup also includes planner covers and stationery that let you spend every day with Conan and the gang.
A Planner Packed with Mystery and Character
The ‘Meitantei Conan’ Special Edition “Weekly Planner weeks” keeps the user-friendly design of the standard Hobonichi weeks but fills every page with original manga art. As a fun twist, the planner’s usual “word of the day” is occasionally replaced with famous character quotes or words selected by Aoyama-sensei himself.
The monthly calendar, which runs from March 2026 to April 2027, spotlights a different character each month. Panels showcasing various expressions of the characters have been selected and laid out from across the 107 volumes of the manga.
The back of the planner is loaded with bonus pages you can enjoy all year round, based on ‘Meitantei Conan’ illustrations and episodes. It features seven unique sections you won’t find anywhere else, like “Detective Trivia That Might Come in Handy Someday,” “Targets of Desire,” and a “Cipher Table You Can Use in Your Planner.”
Choose Your Sleuth Style: Two Cover Designs
You can choose between two cover designs to match your scene or preference. The “Memorial Conan” version features a gorgeous full-color cover illustration with Conan at the center, surrounded by a huge cast of characters from the series. This collectible illustration, originally drawn to commemorate the 100th manga volume, is printed on a material with a canvas-like texture.
The “Conan Motif” version is a blue weeks planner inspired by the jacket Conan wears. Iconic items symbolizing the world of ‘Meitantei Conan’ are expressed through the weave of the tie fabric used for the cover. It uses actual tie material, with the pleasant touch of the weave and a silky sheen as key points.
The weeks for this series also comes with a special underlay sheet modeled after Conan’s “Wristwatch-Type Tranquilizer Gun”. It’s an exclusive collaboration design with a transparent “window” modeled after the watch face, letting you see through to what’s underneath.
Classy Covers and a Full Suite of Stationery
The planner covers feature a classical design inspired by the attire of the British detective Conan himself admires. The inside is lined with numerous iconic scenes extracted from ‘Meitantei Conan’.
Furthermore, it includes a pocket motif based on the keyhole familiar from the back covers of the manga volumes. Slip your favorite card or photo inside, and it becomes visible through the keyhole.
Beyond that, a whole lineup of stationery to use with your planner is available. The collection of seven items includes clear stamps and sheets of stickers perfect for decorating your pages, and a ‘stappo’ case that can store plenty of stationery.
The ‘Hobonichi Techo’ is all about freedom—you can use it expansively to match your taste and lifestyle. If the planner you open every day has a Conan design, it’s sure to give your daily mood a serious boost.
