Genko Yoshi Manuscript Sheet Formula
\text{Genko Yoshi Sheets} = \left\lceil \frac{\text{Total Characters}}{400} \right\rceil, \quad \text{Reading Time} = \frac{\text{Characters}}{500 \text{ CPM}}Standard Japanese manuscript paper (原稿用紙, Genkō Yōshi) contains 400 characters (20 columns × 20 rows). Native Japanese reading speed averages 400–600 characters per minute.
Worked Example
Scenario: A student report containing 1,250 Japanese characters
Total characters: 1,250 chars.
Genko Yoshi sheets: 1,250 / 400 = 3.125 → 4 manuscript sheets.
Estimated reading time: 1,250 / 500 = 2.5 minutes.
Tips & Key Notes
