Hobonichi Techo 2026 Weeks MEGA Cosmo Blue - Compact Weekly Planner

In this review the Hobonichi Techo 2026 Weeks MEGA in Cosmo Blue stands out as a compact, high-capacity weekly planner for people who need both a slim carry and lots of note space. The single biggest reason to buy is its expanded note section: compared to the standard Weeks it provides roughly three times more blank graph pages while remaining only marginally thicker, making it ideal for creatives, planners, and bullet journal users who want a slim planner that still offers abundant writing and sketching room.

Key Features

• Weeks MEGA format: Combines a weekly schedule with a large reserve of blank graph pages so you can plan appointments and immediately jot notes or sketches on the facing page.
• Tomoe River paper: Ultra-thin, fountain-pen friendly paper keeps the planner lightweight while supporting smooth writing and minimal bleed-through.
• Cosmo Blue cover: A chic navy Colors finish with silver foil year marking gives the planner a subtle, professional look that pairs well with a clear cover.
• Compact dimensions: The tall and slim H188 x W94 x T15 mm size fits comfortably in hand, bag, or coat pocket without feeling bulky.
• Comprehensive calendars: Includes yearly calendars for 2025-2027, monthly pages and weekly spreads covering Dec 1, 2025 to Jan 3, 2027 for easy long-range planning.
• Stitch-bound build: Stitch binding and 384 pages create a durable, lay-flat book that is easy to flip through during everyday use.

Who It's For

The Weeks MEGA is aimed at people who favor a minimal, narrow planner but need significantly more note space than a standard weeks-format book provides; designers, students and professionals who sketch, track projects, or keep lists next to their weekly schedule will appreciate the large graph-paper section. The planner's Tomoe River paper and compact profile also suit fountain-pen users who want a portable, stylish planner.

Those who need a daily hourly planner with dense time blocks, a full monthly undated format, or a very thick notebook for heavy handwriting may want to look elsewhere; the Weeks MEGA prioritizes a weekly schedule plus extra graph pages rather than replacing a full daily diary or a thick hardcover notebook.

Pros & Cons

Pros

Cons
