Hobonichi Planner 2025: Original vs. Cousin vs. Weeks Guide

Selecting the ideal planner is a highly personal decision, especially when investing in a premium system like the Hobonichi Techo. For the 2025 edition, the Japanese brand continues to offer its three signature formats: the A6 Original, the A5 Cousin, and the slim, wallet-sized Weeks. Each format caters to distinct organizational habits, writing styles, and daily routines. Finding the right match requires looking beyond aesthetics to evaluate how you interact with paper on a daily basis.

In tropical regions like the Philippines, daily planning habits are often shaped by external factors such as high humidity and active commutes. The paper used in these planners is celebrated for its thinness and smooth texture, but its performance can shift depending on local environmental conditions. Whether you are navigating a humid afternoon in a local cafe or commuting with a packed bag, understanding how these physical formats behave in real-world scenarios will prevent buyer’s remorse.

Compare the Formats: Original, Cousin, and Weeks

To make an informed choice, you must first understand the physical footprint and structural differences of each option. The Hobonichi lineup is built on standardized dimensions, but the layout philosophies of these three models diverge significantly.

The Original is designed around the classic A6 paper size, measuring approximately 105mm by 148mm. It is compact, lightweight, and features a dedicated page for every single day of the year. This daily page layout uses a subtle grid pattern, allowing for flexible writing, sketching, or scheduling. Because of its small size, it slips easily into most everyday carry bags without adding noticeable bulk to your daily load.

The Cousin utilizes the larger A5 format, measuring roughly 148mm by 210mm. It contains the same daily page layout as the Original but adds a comprehensive weekly vertical layout. This weekly section allows you to view your entire week at a glance with hourly time blocks, making it a powerful tool for detailed scheduling. However, the extra pages and larger paper size make the Cousin substantially heavier and thicker than its smaller sibling.

The Weeks is an entirely different format, featuring a slim, elongated shape that measures about 95mm by 186mm. Instead of daily pages, it uses a weekly left-hand page layout paired with a blank grid memo page on the right. This design is highly streamlined, prioritizing high-level scheduling over long-form journaling. It is thin enough to fit into a pocket, a small purse, or the side pocket of a backpack.

While all three planners traditionally feature ultra-thin, high-quality paper designed to keep the books manageable, exact paper specifications and page counts can vary. For the 2025 editions, it is always best to verify the specific paper weight and structural details on the manufacturer’s official product listings before purchasing.

Match Your Planning Style to the Right Size

Before choosing a size, take a moment to analyze your daily writing habits and lifestyle. A planner is only effective if it fits naturally into your existing routine without feeling like a chore to carry or fill.

Start by assessing your average daily writing volume. Do you tend to write long, reflective journal entries, or do you prefer quick, bulleted task lists? Consider also whether you enjoy decorating your pages with stickers, washi tape, photos, or watercolor washes. These creative additions add physical thickness to the book over time, which can cause a larger planner to swell significantly.

Your physical environment also plays a major role in this decision. If you work primarily from a dedicated home office desk, a larger, heavier planner is easy to keep open all day. Conversely, if you are constantly on the move, commuting through busy transit systems, or working from different coffee shops, a lightweight and highly portable format will likely serve you better.

Choose Original (A6) for Portability and Daily Focus

The A6 Original is the quintessential choice for those who want a dedicated daily canvas without the physical burden of a large book. It is ideal for capturing quick daily logs, tracking personal habits, or keeping a gratitude journal. The compact page size encourages you to focus on the most important events of the day rather than feeling pressured to fill up a massive blank space.

This size is particularly well-suited for individuals with small bags or those who prefer to travel light. It takes up minimal space on a small cafe table, making it easy to pull out for a quick update during a lunch break.

However, the A6 format does present some trade-offs. The limited horizontal space can feel restrictive if you have large, sweeping handwriting or if you like to divide your pages into multiple vertical columns. If you prefer to keep detailed project timelines alongside your daily tasks, you may find yourself running out of room quickly.

Choose Cousin (A5) for Detailed Logging and Journaling

If you view your planner as a complete life repository, the A5 Cousin is unmatched in its utility. The generous page size provides ample room for detailed hourly scheduling, extensive daily journaling, and creative scrapbooking. You can easily paste receipts, photos, and memorabilia onto the pages without covering up your written notes.

The inclusion of both weekly vertical columns and daily pages makes the Cousin a favorite for professionals, students, and busy heads of households. You can use the weekly pages for time-blocking your meetings and classes, while reserving the daily pages for meeting minutes, study notes, or personal reflections.

The primary drawback of the Cousin is its physical weight and footprint. Carrying an A5 planner, especially when paired with a thick protective cover, adds noticeable weight to your bag. If your daily commute involves walking long distances or standing on crowded trains, you may find yourself leaving this larger book at home on your desk.

Choose Weeks for Minimalist Weekly Overviews

The Weeks format is designed for the ultimate minimalist who values efficiency and portability above all else. By presenting the entire week on a single page spread, it allows you to see your upcoming deadlines, appointments, and tasks without flipping through multiple pages. The adjacent memo page is perfect for shopping lists, weekly goals, or rapid logging.

This slim profile makes the Weeks incredibly easy to carry everywhere. It functions beautifully as a companion planner for work tasks, a dedicated fitness tracker, or a portable budget book.

The limitation of the Weeks is its lack of space for deep reflection or detailed daily journaling. If you enjoy writing long-form entries about your day or need to block out your schedule hour by hour, the compact horizontal layout will likely feel too cramped.

Practical Checks Before You Buy

Once you have identified the format that aligns with your lifestyle, there are several practical factors to verify before making your final purchase.

Cover and Accessory Compatibility: It is crucial to remember that Hobonichi covers, clear protective covers, and pencil boards are size-specific. An A6 cover will not fit an A5 Cousin, and the Weeks requires its own dedicated slim accessories. When browsing online marketplaces or local specialty shops, double-check the product labels to ensure the accessories you select match the exact model and year of your planner.

Paper and Ink Testing: The lightweight paper used in these planners is highly regarded by stationery enthusiasts, but its performance depends heavily on the writing instruments you use. In humid tropical climates, ink can take longer to dry on coated, non-absorbent paper. If you plan to use fountain pens, heavy gel pens, or wet inks, it is wise to perform a small test on the blank memo pages at the back of the book. This allows you to observe drying times, ghosting, and potential bleed-through before committing to your main pages.

Budget and Value: Premium planners represent a financial investment, and prices can vary depending on where you purchase them. Compare the base prices in ₱ across authorized local stationery boutiques and official online distributors. Keep in mind that purchasing a separate cover can significantly increase the total cost, so factor in these accessories when calculating your overall budget.

Final Decision Framework

To help you make your final decision, use this simple framework to match your needs to the correct Hobonichi model:

• Choose the Original (A6) if: You want a dedicated daily page for journaling or task tracking, prefer a highly portable book that fits in small bags, and have relatively compact handwriting.
• Choose the Cousin (A5) if: You need both weekly time-blocking and daily pages, enjoy scrapbooking or pasting ephemera, and plan to keep your planner primarily on a desk.
• Choose the Weeks if: You prefer a high-level weekly overview, value a slim and lightweight design that fits in a pocket, and do not require dedicated daily pages.

Verify first if: You are transitioning from a digital calendar system or a standard thick-paper planner. The thin paper and unique layouts of the Hobonichi system may require a short adjustment period as you find your preferred writing tools and layout flow.

Before finalizing your order, always check the official 2025 release details and authorized retailer listings to confirm any minor structural updates, cover designs, or layout changes for the upcoming year.

Frequently Asked Questions (FAQ)

Can I use the same cover for both Original and Cousin?

No, you cannot use the same cover for both models. The Original is an A6 size, while the Cousin is a much larger A5 size. Because of this significant difference in physical dimensions, covers, clear protective sleeves, and pencil boards are not interchangeable. Always verify the product label or retailer description to ensure the cover matches the exact planner model you own.

Is the thin paper suitable for fountain pens?

The lightweight paper used in these planners is highly popular among fountain pen users due to its ability to showcase ink shading and sheen. However, actual performance can vary based on your specific ink formulation, nib size, and local humidity levels. In humid climates, wet inks may experience longer drying times. It is highly recommended to conduct a quick ink test on the back pages of your planner to check for ghosting or feathering before writing extensively.
