## What is Kata Japanese?

Build real Japanese sentences from reusable patterns, not isolated vocabulary.

Kata Japanese organizes 144 practical sentence forms into particles, politeness, verb forms, adjectives, word order, and connections. Read an English meaning cue, build the Japanese sentence, reveal the pattern, and rate your recall so difficult forms return sooner.

Features:
• Five-pattern daily practice
• 144 Japanese sentence patterns with original examples
• Six focused grammar categories
• Japanese speech playback
• Smart review for difficult patterns
• Search across Japanese, English, and explanations
• Reviewed, mastered, and streak progress

The first 24 patterns are free. Kata Japanese Pro is a one-time purchase that unlocks the remaining 120 patterns and all learning tools. Purchases can be restored from Settings.

Speech uses an available Japanese system voice.
