1. What is Rakuyomi?

Rakuyomi (rakuyomi.net) is a web platform for intensive Japanese reading comprehension practice (JLPT N1–N5), integrating furigana for each character, a one-click dictionary lookup without interrupting the reading flow, and detailed explanations of the thinking process behind multiple-choice questions.

2. Problems Addressed

When practicing reading Japanese (especially for JLPT N3–N1 reading tests or news articles, practical documents), learners often encounter three major obstacles:

• Disruption of reading flow and loss of concentration: Having to continuously copy/paste or open an external dictionary tab whenever encountering new words or unfamiliar Kanji.
• Automatic furigana being inaccurate: Common translation tools or extensions often assign incorrect readings to Kanji based on context, causing confusion in learning.
• Taking tests without understanding the essence: Most materials only provide simple A/B/C/D answers without analyzing the traps of the questions, leading learners to take many tests while their reading comprehension (Dokkai) scores remain stagnant.

Rakuyomi effectively addresses this issue with a zero-friction reading experience: click on any word to understand its meaning immediately, compare it with an accurate bilingual translation, and fully grasp the logic of each question through detailed explanations.

3. Key Features

• Library of 760+ standardized JLPT reading comprehension passages (N1 to N5): A comprehensive collection of various test formats over the years (short texts, medium texts, long texts, information retrieval), with support for turning Furigana on/off according to each learning level.
• Inline one-click dictionary lookup (Zero-friction Dictionary): Click directly on any vocabulary in the text to see its Vietnamese meaning, JLPT level, part of speech, and stroke order of Kanji without leaving the page.
• Bilingual side-by-side translation: The side-by-side bilingual display mode helps learners untangle complex grammatical structures and capture the author's intent clearly.
• Reading comprehension quizzes & In-depth answer explanations: Instant grading with detailed explanations analyzing the reasons for choosing the correct answer, pointing out references in the text, and analyzing the mistakes in distractor options.
• Extended toolset (Text analysis, Dictionary & Reflex game): Automatically analyzes text and assigns furigana to any Japanese passage; Kanji stroke order dictionary lookup system; along with a mini-game that practices five-dimensional vocabulary reflexes to quickly reinforce word stock.

4. Who Should Use It?

• JLPT examinees (N3, N2, N1): Those who want to improve their scores in the Reading Comprehension (Dokkai) section – the part of the exam with the highest failure and score loss rates.
• Engineers, working professionals, and international students in Japan: Need to improve their reading speed of emails, technical documents, and daily news without being interrupted by vocabulary barriers.
• Japanese language teachers: Need a rich and standardized source of reading materials with ready-made furigana and detailed analyses for lesson planning.
