Plan your year with a compact, ultra-functional Japanese planner. Mark’s 2026 Notebook Calendar S – Vertical B6 Monthly Planner starts in January 2026 and runs through December 2026, giving you a full year of monthly overviews in a slim notebook format.
Despite its portable B6 size (approx. 13.5 × 18.6 × 1.0 cm), the vertical notebook calendar opens flat to reveal a spacious monthly block layout, making it easy to see your entire month at a glance. High-grade construction paper provides a smooth writing experience with minimal bleed-through, ideal for gel pens, ballpoint pens, and highlighters.
Each month is supported by ruled memo pages, so you can keep to-do lists, work tasks, study plans, fitness logs, or household schedules together in one place. The planner also includes an annual calendar and international holiday icons for 10 countries (Japan, US, UK, France, Italy, Spain, Germany, China, Hong Kong, Korea), plus week numbers—perfect if you’re coordinating across time zones or working with overseas clients.
Finished with a W-ring binding, this notebook calendar lies flat or folds back on itself, making it easy to write anywhere: at your desk, in a café, or on the go. It’s a clean, minimal, and highly practical planner for students, professionals, and anyone who loves Japanese stationery.
