Japanese Manuscript Paper (Genkō Yōshi): Layout and Page Count Guide
When preparing a Japanese writing assignment, essay, contest submission, or translation, you may need to check how your text actually fits on manuscript paper. Genkō yōshi (原稿用紙) — also written genko yoshi — is a traditional Japanese manuscript grid where each character occupies one square cell, text runs top to bottom, and columns proceed from right to left. Because paragraph indentation, line breaks, and punctuation placement can all affect the layout, a simple character count alone cannot reliably predict how many sheets your text will fill.
This viewer lays out your text on a genkō yōshi grid and calculates total characters, characters excluding spaces, raw sheet count by character count, and actual sheet count by layout — all switchable between 400-character and 200-character formats.
📌 When you need a genko paper viewer
| Situation | How this tool helps |
|---|---|
| Japanese writing assignment | Preview vertical layout and paragraph placement before submitting. |
| Contest or journal submission | Calculate approximate sheet count against a 400- or 200-character limit. |
| Translation or creative writing review | See how horizontally composed text looks in a vertical genkō yōshi grid. |
| Character count with and without spaces | Compare total characters against the space-excluded count side by side. |
1. What is genkō yōshi?
Genkō yōshi (原稿用紙), or genko yoshi, is a type of manuscript paper divided into a uniform grid of cells. As a rule, one character is written in each cell. In the traditional vertical writing style (tategumi), characters are placed top to bottom, and columns run from right to left across the page.
- 400-character genkō yōshi: 20 characters per column across 20 columns (20×20)
- 200-character genkō yōshi: 20 characters per column across 10 columns (20×10)
As a rough guide, one 400-character sheet is about the amount of text you see across a two-page spread in a typical Japanese paperback book, while one 200-character sheet is closer to the amount on a single page. When an assignment, contest, or submission guideline specifies a length such as “within 5 sheets,” always confirm which sheet format is meant.
2. Why raw character count and actual sheet count differ
Dividing your character count by 400 or 200 gives only an approximation. On actual genkō yōshi, several factors consume cells without adding characters:
- Sheets by character count: total characters ÷ cells per sheet
- Sheets by actual layout: reflects line breaks, blank lines, paragraph indents, and kinsoku handling
For example, a text under 400 characters can still run onto a second sheet if it has many short paragraphs or frequent line breaks. Check both figures when matching a required page count.
3. Basic genkō yōshi layout rules
Toggle the options in this tool to see how each rule affects the layout in real time.
- Paragraph indent: the first cell of each new paragraph is left blank as an indent.
- Respect line breaks: explicit line breaks in your text advance to the next column.
- Remove blank lines: empty lines in the input text can be ignored in the layout
- Kinsoku handling: closing punctuation and brackets are prevented from appearing at the top of a column.
Characters like 。, 、, and 」 look awkward at the head of a column.
With basic kinsoku on, they are tucked alongside the last character of the preceding column,
keeping the layout closer to standard manuscript form.
4. 400-character vs. 200-character genko paper
The 400-character sheet (genkō yōshi 400-ji) is the standard format for Japanese writing assignments, literary manuscripts, and contest submissions. Its larger capacity makes it practical for longer texts.
The 200-character sheet has half as many columns per page and is suited to shorter texts or practice writing. The same text will usually require more sheets in the 200-character format than in the 400-character format.

🛑 Checklist before submitting your manuscript
- Is the required format a 400-character sheet or a 200-character sheet?
- Does the submission count sheets by raw character count or by actual layout?
- Does the paragraph indent setting match the submission guidelines?
- Is the space handling option consistent with the intended text?
- Do punctuation marks and closing brackets appear in awkward positions in the preview?
FAQ
Q. Can non-Japanese text be laid out on the grid?
Yes. Text containing kanji, hiragana, katakana, Korean, Latin letters, digits, and symbols can all be placed on the grid.
In this viewer, full-width Latin letters and digits
such as Ａ, Ｂ, and １
are treated like Japanese full-width characters:
they occupy one cell each without rotation.
Half-width Latin letters and digits are rotated and grouped in pairs,
with up to two characters placed in one cell.
Q. Are spaces and line breaks counted as characters?
The tool displays both total characters and characters excluding spaces. The "sheets by actual layout" count also factors in line breaks, blank lines, and paragraph indents, since these all occupy column space.
Q. Can I print or save the layout as a file?
This tool is designed for browser-based layout preview and character counting. For a printable or submittable manuscript file, please use the official form or template provided by your submission venue.
