Douzo FAQ

How does Douzo help improve reading fluency in Japanese?

Douzo helps improve reading fluency by having users type full Japanese sentences, hiragana, and katakana in romaji. This process forces active engagement with the text, including kanji, hiragana, and katakana, building natural reading speed and recognition through repeated exposure and practice.

Can I use Douzo to prepare for specific sections of the JLPT exam?

While Douzo's content is aligned with JLPT N5-N1 levels and includes vocabulary and sentences, it primarily focuses on reading and typing practice. It can be a valuable supplementary tool for vocabulary acquisition and reading comprehension, but it does not cover all JLPT exam sections like listening or grammar explicitly.

What kind of data can I export from Douzo for further study?

Douzo allows you to export your study data, specifically your review notes and tracked mistakes, as either a CSV file or Anki flashcards. This enables you to integrate your practice results into other study methods or flashcard systems for continued learning and spaced repetition.

How does the 'Quick Level Check' feature work to determine my starting point?

The 'Quick Level Check' uses 10 adaptive questions to assess your current Japanese proficiency. Based on your responses, it dynamically adjusts the difficulty and guides you to an appropriate starting level within the JLPT N5-N1 content, ensuring the practice is suitably challenging.

Is there any way to track my progress or performance over time within Douzo?

Douzo tracks your mistakes and keeps them ready for review. While it doesn't offer a comprehensive progress dashboard, the ability to export review notes and study data allows users to manually track their performance and focus on areas needing improvement outside the platform.
