Stop translating Japanese in your head. Start processing it automatically. Japanese Reflex uses fast, interactive drills to develop your Japanese Brain—the mental pathways that let you understand Japanese directly, without translating everything into English first. Traditional study can teach you thousands of words and grammar points, but knowledge alone does not guarantee fast processing. Even learners who have passed JLPT N2 or N1 may still struggle to follow conversations or respond without hesitation. Japanese Reflex bridges that gap. It is more than a vocabulary or grammar app—it is a reflex training system that turns what you know into fast, automatic Japanese ability. BUILD YOUR JAPANESE REFLEXES Short, audio-driven drills train you to: • Recognize grammar patterns instantly • Process spoken Japanese at conversational speed • Identify particles and sentence roles automatically • Understand verb forms without conscious translation • Distinguish transitive and intransitive verbs • Navigate conditionals, requests, keigo, and nuance • Respond based on meaning instead of memorized rules Each drill challenges you to make quick, accurate decisions, moving Japanese processing from slow and conscious to fast and intuitive. MEASURE YOUR JAPANESE BRAIN Japanese Reflex includes 26 Reflex Drills targeting critical—and often difficult—grammar and meaning patterns. Every completed drill gives you a Reflex Score combining accuracy and response speed. The app averages your five most recent scores across all 26 drills to calculate your overall Japanese Brain Score: a measure of real-time Japanese processing ability ranging from 0 to 105. Your goal is to raise your Japanese Brain Score above 90—the level where processing and understanding Japanese become fast, intuitive, and automatic. ADAPTIVE PRACTICE Adaptive Practice identifies the specific grammar skills and meaning patterns giving you trouble, then gives you extra practice with those weaker areas. Each session adapts to your performance and continues working on difficult skills until you can answer correctly and consistently—helping turn weak points into automatic reflexes. MASTER YOUR MISSES Master Your Misses creates focused review sets from questions you answered incorrectly. Work directly on your weak points until the correct response becomes automatic. CHALLENGE FRIENDS Create custom challenges, invite friends, and compete on leaderboards. Whether you are preparing for the JLPT, living in Japan, or studying with classmates, Challenges make consistent practice more engaging. TRY IT FREE Start with free access to every Reflex Drill.
