## What is J?

Learn Japanese and pass JLPT with a clear plan, built by teachers in Tokyo, at your own pace.

J-Standard is a complete, self-paced JLPT course built by the teachers at Coto Academy, a Japanese language school in Tokyo and Yokohama that has taught thousands of learners from around the world.

Whether you're aiming for N5 or N2, J-Standard gives you a clear, structured path to exam day. No guesswork about what to study next, no juggling five different apps.

WHAT YOU GET
• Structured courses for each JLPT level, from N5 to N2
• Grammar lessons with clear explanations and real example sentences
• Vocabulary and kanji practice organized by level
• Reading and listening practice in the JLPT format
• Quizzes after each lesson to check what you've learned
• Progress tracking so you always know where you stand

BUILT BY TEACHERS, NOT ALGORITHMS
Every lesson was written by experienced Japanese teachers who prepare students for the JLPT every year. The content follows what the exam tests, not just random word lists.

STUDY ANYWHERE
Fit your study into your commute, lunch break, or evening. Your progress syncs across your phone and the J-Standard website, so you can pick up exactly where you left off.

FOR COMPANIES AND SCHOOLS
J-Standard also supports teams. Companies, schools, and organizations can give employees or students access and follow their progress through a dedicated dashboard. Contact us to learn more.
