Stop memorizing random sounds. Start understanding what they mean. Japanese Grammar Rules is a grammar-first Japanese learning app built to turn the "walls of sound" you encounter into windows of understanding. Most beginners struggle because they can read the sounds (kana), but don't know who did what, to whom, when, or why. Japanese Grammar Rules provides the "Ashiba" (scaffolding) you need to bridge that gap. We focus on structured grammar because you cannot learn a language just by hearing it in the background—you learn by understanding input. With 67 progressive lessons, Japanese Grammar Rules takes you from absolute beginner to reading real Japanese content (like manga) by teaching you the underlying logic of the language. Features - 67 Structured Lessons: Organized logically around essential Japanese grammar patterns. - Phrase Breakdowns: Every sentence is dissected—particles, conjugations, and vocabulary—so nothing is a mystery. - Authentic Native Audio: High-quality audio for every phrase and dialogue to train your ear from day 1. - Practical Dialogues: See grammar in action through natural, conversational examples. - Smart Reference: Instantly access grammar and vocabulary guides whenever you need them. Why Japanese Grammar Rules? - Grammar as Scaffolding: Understand the rules so you can break down any sentence you hear or read. - Comprehensible Input: We don't just give you phrases; we explain exactly how they are built. - Real Momentum: Reach the point of reading real Japanese sooner by focusing on the core patterns that actually matter. Why I Built Japanese Grammar Rules I’ve always loved Japan. I’ve traveled there many times, and having real conversations with locals was always my dream. When I decided to seriously learn Japanese, I tried many tools. I used Duolingo and Rosetta Stone, but they felt too gamified and didn’t explain enough grammar. I studied from traditional textbooks like Minna no Nihongo, which were excellent but lacked an interactive, modern digital format. I found myself constantly relying on a jisho (辞書) Japanese dictionary to look up words and desperately wanted a free language app that wove vocabulary and grammar together naturally. My goal was clear: properly master 日本語 (Japanese) and prepare for the JLPT N5 without feeling lost in a sea of memorization. Japanese Grammar Rules is the tool I wish I had: a clear, logical, and audio-rich path to true Japanese comprehension. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
