Japanese stationery and Japanese language study are a natural pair. The same companies that produce the world’s best pens, notebooks, and highlighters also produce tools specifically designed for the Japanese education system. When you study Japanese with Japanese stationery, you’re using tools engineered for exactly this purpose — tools that Japanese students themselves rely on from elementary school through university.
Living in Japan, we’ve watched students at every level use these tools daily. The precision of a Kokuyo Campus notebook, the organization of a Kokuyo Campus Loose Leaf system, the color-coding power of Zebra Mildliner highlighters — these aren’t luxuries. They’re the practical foundation of effective study. Here’s how to build your own Japanese stationery study toolkit.
The Core Notebook Setup
Primary Study Notebook: Kokuyo Campus Notebook (B5, Dotted Line)
Price: ~$4 | Size: B5 (6.9 x 9.8 inches)
The Kokuyo Campus notebook is the backbone of our study system. The B5 size is the standard Japanese student notebook format — large enough for detailed notes but portable enough for daily carry. The dotted line ruling provides structure without visual clutter, making it perfect for neat vocabulary lists, grammar notes, and example sentences.
We use one notebook per study topic: one for grammar, one for vocabulary, one for kanji practice. The Campus notebook’s quality paper handles gel pen ink without bleeding, and the binding lies flat for comfortable two-page spreads.
Kanji Practice Notebook: Kokuyo Campus Kanji Practice (12mm Grid)
Price: ~$6
Dedicated kanji practice notebooks with cross-guide grids are non-negotiable for serious kanji study. The 12mm grid with internal cross lines teaches proper character proportions — where to place each stroke relative to the center of the square.
We go through one of these notebooks every 2-3 months of consistent practice.
Loose-Leaf Option: Kokuyo Campus Loose Leaf Paper
Price: ~$5 (100 sheets)
For learners who prefer to reorganize notes by topic rather than chronologically, Kokuyo Campus loose-leaf paper in a binder is an excellent alternative to bound notebooks. You can group vocabulary by theme, move grammar notes between sections, and add pages to any section as needed.
Pair with a Kokuyo Campus Smart Ring binder for a slim, portable system that doesn’t add bulk to your bag.
Color-Coding System
Color-coding is not optional for Japanese study — it’s a force multiplier. Here’s the system we use:
Highlighters: Zebra Mildliner (Full Set)
Price: ~$15 (15-color set)
Zebra Mildliner highlighters have two tips (broad chisel and fine bullet) and come in soft, non-distracting pastel colors. Their mild fluorescence is easier on the eyes during long study sessions than traditional neon highlighters.
Our color-coding system for Japanese study:
- Mild Blue — Verbs and verb conjugations
- Mild Pink — Adjectives (i-adjectives and na-adjectives)
- Mild Green — Grammar patterns and particles
- Mild Yellow — New vocabulary words
- Mild Orange — Cultural notes and exceptions
- Mild Purple — Example sentences worth memorizing
This system makes scanning your notes for specific information instant. When you need to review all grammar patterns, look for green. When you want example sentences, look for purple.
Colored Pens: Pilot Juice Up Color Set
Price: ~$15 (10-color set)
For writing (rather than highlighting), a set of colored gel pens adds another organizational layer. We use different colors for different elements within notes:
- Black — Main text and definitions
- Red — Corrections, furigana readings, mistakes to remember
- Blue — Example sentences
- Green — Personal mnemonics and memory aids
The Pilot Juice Up in 0.4mm provides the fine precision needed for detailed notes with furigana annotations.
Organization Tools
Sticky Notes: 3M Post-it or Stalogy
Price: ~$5-8
Small sticky notes (1.5 x 2 inches) serve multiple purposes in Japanese study:
- Textbook annotations — Stick notes on textbook pages with additional explanations or mnemonics
- Vocabulary flags — Mark pages in your dictionary where important words appear
- Grammar reminders — Post grammar rules on your desk or wall for passive review
- Corrections — Cover mistakes in your notebook with a sticky note and write the correction on top
Tabs and Index Dividers
For loose-leaf binder setups, labeled divider tabs keep sections organized. We divide our study binder into: Grammar, Vocabulary (by JLPT level), Kanji, Reading Notes, Listening Notes, and Review/Mistakes.
Pencil Case: Choose One That Fits Your Tools
A quality Japanese pencil case keeps your study tools organized and portable. We recommend a standing pencil case (like the Kokuyo NeoCritz) that opens into a pen cup on your desk — easy access during study sessions, compact for transport.
Writing Instruments
Primary Writing Pen: Uni Jetstream 0.5mm
Price: ~$3
The Uni Jetstream is our top pick for general note-taking during study. The low-friction Jetstream ink glides across paper with minimal effort, producing dark, professional-looking notes. The 0.5mm tip is versatile enough for both regular notes and small furigana annotations.
The Jetstream’s key advantage for study is its rapid dry time and resistance to smearing. You can flip pages, rest your hand on fresh notes, and write quickly without worrying about ink transfer.
Backup Pen: Zebra Sarasa Clip 0.4mm
Price: ~$2.50
The Zebra Sarasa Clip is our secondary recommendation — slightly smoother than the Jetstream for extended writing, with a clip design that secures it to your notebook or textbook binding. Available in 45+ colors for those who want their color-coding done with a single pen type.
Pencil: Tombow Mono 2B
Price: ~$1
A traditional pencil in 2B hardness is ideal for kanji practice, rough notes, and textbook exercises that you might want to erase. The Tombow Mono writes smoothly and erases cleanly. Pair it with a Tombow Mono eraser for precise corrections.
Eraser: Tombow Mono Zero
Price: ~$5
The Tombow Mono Zero is a precision eraser shaped like a mechanical pencil. Its small, retractable eraser tip lets you erase individual characters without disturbing surrounding text. For kanji practice where you often need to correct a single character in a line, this precision is invaluable.
Supplementary Tools
Correction Tape: Tombow Mono Air
Price: ~$4
For pen-written notes that need correction, quality correction tape is essential. The Tombow Mono Air applies smoothly, covers cleanly, and accepts overwriting with any pen type. We use it to fix mistakes in our vocabulary notebooks rather than crossing out errors.
Ruler: For Underlining and Section Dividers
A 15cm clear ruler is useful for drawing neat section dividers in your notebook, underlining important grammar points, and creating clean vocabulary tables. Japanese rulers are thin, precise, and often feature both metric and inch markings.
Paper Clips and Binder Clips
Small paper clips mark your current study page in textbooks. Binder clips hold together practice worksheets and hiragana/katakana practice sheets.

Frequently Asked Questions
Do I really need all this stationery to learn Japanese?
No. You can learn Japanese with a single notebook and a single pen. But quality stationery makes study more organized, more efficient, and genuinely more enjoyable. The color-coding system alone saves significant time when reviewing notes. Start with the Essential tier and add tools as you discover what benefits your study style.
What notebook size should I use?
B5 (6.9 x 9.8 inches) is the Japanese standard and our recommendation. A5 is more portable but offers less space for detailed notes. If you study primarily at a desk, B5 is ideal. If you study on commutes or in cafes, A5 may be more practical.
Can I use a digital tablet instead of paper?
You can, and tools like the iPad with Apple Pencil are excellent for certain aspects of Japanese study. However, research consistently shows that handwriting on paper produces stronger memory encoding than writing on screens. We recommend paper for kanji practice and vocabulary building, where retention is the primary goal. Use digital tools for reading practice, listening practice, and flashcard systems.
How should I organize my study notebooks?
We recommend separate notebooks for each major study area: Grammar, Vocabulary, Kanji Practice, and Reading Notes. Within each notebook, date every entry and leave a few blank lines between topics for future additions. Alternatively, use a loose-leaf binder system where you can reorganize pages freely.
Where can I buy Japanese stationery in the US?
Amazon carries most Japanese stationery brands. Specialty retailers like JetPens and Stationery Pal offer wider selections. Outside the US, the Amazon links on our site automatically redirect to your local Amazon store (Amazon.co.uk, Amazon.ca, Amazon.com.au, and more), so you can shop with local shipping and pricing.
