Genkō Yōshi (Japanese Manuscript Paper)
Gridded writing paper used in Japan with a standard format of 400 squares (20 columns × 20 rows), designed for composing Japanese text at one character per square.
Genkō yōshi (原稿用紙) is the traditional Japanese manuscript paper consisting of a grid of squares, each designed to hold exactly one character. The standard format features 400 squares arranged in 20 vertical columns of 20 squares each, written from right to left and top to bottom following traditional Japanese writing direction. This format has been the backbone of Japanese literary composition since the Meiji era, used by students for essays, by authors for manuscripts, and by publishers as the basis for page count estimation. The 400-character sheet became the de facto unit of Japanese text measurement: a "two-sheet essay" means 800 characters, and professional writing rates are often quoted per 400-character sheet.
| Where it is in the grid | How the squares are used | How it is counted |
|---|---|---|
| First square of line 1 (the shaded square) | A new paragraph starts one square in | The square left blank still counts as one square |
| Seventh square of line 1, 、 | Punctuation takes a square of its own, just like a character | One square |
| The 。 sitting outside the right edge of line 1 | Punctuation that would land at the start of a line stays at the end of the previous line | No extra square is used |
| Start of line 3 | Dialogue begins on a new line, wrapped in corner brackets | 「 and 」 each take one square |
Twenty lines of 20 squares make up the 400-square sheet. Because a square left blank for indentation still counts, the same passage fills more squares than a plain character count would suggest. The sample sentences describe cherry blossoms in a schoolyard and end with a line of dialogue. Traditional sheets are written in vertical columns from right to left; the grid is laid out horizontally here so that it reads naturally on screen.
In the digital age, genkō yōshi remains surprisingly relevant. Japanese word processors like Ichitaro and even Microsoft Word offer genkō yōshi templates that replicate the grid layout on screen. School assignments in Japan still frequently specify length in "sheets of genkō yōshi" rather than word counts, and university entrance exams require handwritten essays on physical genkō yōshi. The 400-character standard also influenced Japanese web culture: early blog platforms and mobile sites often used 400-character blocks as content units. The connection to character counting is direct and intuitive, since every filled square is one character, making it trivial to verify that an essay meets its length requirement by counting filled squares.
The genkō yōshi system highlights a fundamental difference between Japanese and English text measurement. English measures text in words, which vary in length from 1 to 20+ characters. Japanese measures in characters, where each character carries roughly the semantic weight of an English word. A 400-character Japanese essay conveys approximately the same amount of information as a 200-250 word English essay. This difference propagates into modern digital contexts: Japanese Twitter users can express more per post within the 280-character limit than English users, and Japanese web forms with character limits feel more generous than their English equivalents. For character counting tools serving multilingual users, understanding this information density gap is essential for providing meaningful length guidance across languages.
Frequently Asked Questions
- How many characters fit on one sheet of genkou yoshi?
- The standard 400-character sheet holds 20 characters per line x 20 lines = 400 characters. A "two-sheet" assignment therefore means 800 characters, "three sheets" means 1,200 characters, and "five sheets" means 2,000 characters.
- Does punctuation occupy a square on genkou yoshi?
- Yes. Punctuation marks and brackets each take one square and count as one character. When a punctuation mark would fall at the start of a line, the convention is to keep it at the end of the previous line as hanging punctuation rather than pushing it down, and it consumes no extra square.
- How do you convert for 200-character genkou yoshi?
- A 200-character sheet (20 characters x 10 lines) is half the 400-character format, so the same text needs twice as many sheets. For example, 800 characters fill 2 sheets of 400-character paper but 4 sheets of 200-character paper.
