Find out what makes a Japanese passage difficult.
Hane’s Japanese text analyzer turns an unspaced passage into a vocabulary map. Paste a sentence, news excerpt, story, or study note to inspect readings and meanings, estimate its JLPT range, and decide what to learn before you read it closely.
Word readings and definitions
Focus a highlighted segment to see its kana reading and English Jitendex definition. Common inflected words are linked to a likely dictionary form where available.
JLPT vocabulary profile
See matches across N5, N4, N3, N2, and N1 in one distribution. Use the result to spot advanced vocabulary before choosing a text for reading practice.
Reading difficulty estimate
The 0–100 score combines listed vocabulary, kanji levels, sentence length, and selected grammar signals. It is a comparative study aid—not an official JLPT grade.
How to use the result

Common questions
About the Japanese text analyzer
Is the Japanese text analyzer free?
Yes. The analyzer is free to use, requires no account, and accepts up to 12,000 characters at a time.
Does Hane upload or store the Japanese text I paste?
No. Dictionary lookup and difficulty analysis run in your browser. Your pasted text and opened files are not sent to Hane or a third party.
Is the JLPT level score official?
No. JLPT vocabulary lists and level boundaries are not officially published. Hane provides a study estimate based on listed vocabulary, kanji levels, sentence length, and selected grammar signals.
Is this a Japanese translator?
No. The tool segments Japanese text and shows word readings, English dictionary definitions, likely base forms, JLPT levels, and reading difficulty. It does not produce a full sentence translation.
