Count Hiragana, Katakana, Kanji, Japanese punctuation, and script ratios to inspect Japanese text composition in mixed-language content.
Japanese Character Counter converts raw pasted text into a clear analytics report. It shows the main count, supporting metrics, density, and an interpretation that helps you decide whether the text needs cleanup or review.
All processing happens locally in the browser. No server upload is required for pasted text.
Example input: 日本語の文章です。カタカナ、ひらがな、漢字をそれぞれ数えます。AIとSEOも含みます。
Japanese Character Counter uses deterministic character matching and script-aware checks where applicable. It also calculates total characters, lines, density, frequency, and category-specific quality signals.
Language detection is heuristic, not a full linguistic classifier. For legal, academic, or production validation, review the exported report manually.
Paste Japanese text and run the tool. It separates hiragana, katakana, kanji, and Japanese punctuation.
Yes. The script ratio report flags unusually high katakana usage.
Use Kanji extraction mode to output only CJK Han characters from the input.
Japanese punctuation marks are reported separately from hiragana, katakana, and kanji.
Yes. The tool reports Japanese character density and script composition in mixed content.
