这是什么What is this

「日语语法笔记」是一份免费、双语（中文 + 日语）的 JLPT N5 → N2 语法学习材料，按 8 周节奏规划，共 73 课、400+ 个语法点。每个语法点包含：

  • 接续规则：动词 / 形容词 / 名词的具体接续方式
  • 3+ 例句：覆盖日常对话和考试常见语境
  • 辨析：和易混淆语法的对比（如「は」vs「が」、「たら」vs「なら」）
  • 易错点：中文母语者特别容易踩的坑
  • 间隔复习：当天 → 1 → 4 → 7 → 14 → 30 天勾选清单

内容免费、无广告、无追踪。

"Japanese Grammar Notes" is a free, bilingual (Chinese + Japanese) JLPT N5 → N2 grammar study set, structured as an 8-week curriculum of 73 lessons covering 400+ grammar points. Each grammar point includes:

  • Conjugation rules: how it combines with verbs / adjectives / nouns
  • 3+ example sentences: covering daily conversation and exam-style contexts
  • Comparisons: side-by-side with easily confused grammar (e.g. は vs. が, たら vs. なら)
  • Common pitfalls: mistakes Chinese native speakers tend to make
  • Spaced repetition: review checklist for day 0 → 1 → 4 → 7 → 14 → 30

Free, no ads, no tracking.

为什么做这个Why I built it

我从 2026 年 4 月开始系统学日语，目标 8 周内拿下 JLPT N2。准备过程中发现：

  • 中文圈的日语语法资料要么过于碎片化（散落在各种论坛、知乎回答），要么过于学院派
  • 教科书（《大家的日本语》《新完全マスター》等）对中文母语者来说，「中文翻译」和「中文讲解」之间有断层——很多语感差异翻译里讲不清楚
  • 没有一份完整覆盖 N5 → N2、又用中文母语者视角讲解的免费在线资料

所以我决定边学边记，把整套笔记开源出来。最初是给自己复习用，后来发现可能对其他中文母语日语学习者也有用，于是托管成网站。

I started studying Japanese seriously in April 2026, aiming for JLPT N2 in 8 weeks. While preparing, I noticed:

  • Chinese-language Japanese grammar material online is either too fragmented (scattered across forums and Q&A sites) or too academic
  • Textbooks (Minna no Nihongo, Shin Kanzen Master) leave a gap between "Chinese translation" and "explanation tuned for Chinese speakers" — much of the nuance gets lost
  • No single resource covers N5 → N2 completely while explaining from a Chinese-native-speaker perspective

So I decided to take notes as I learn and open-source everything. It started as a personal study aid; publishing it as a website was a side effect.

内容生产方式How content is produced

每节课的笔记结构来自我自己学日语的实际节奏。例句和辨析参考了：

  • 教科书：《大家的日本语 初级 I / II》、《新完全マスター 文法 N3 / N2》、《日本語総まとめ N3 / N2 文法》
  • 在线参考：沪江日语、Bunpro、Tofugu、日本語教師の広場
  • 真题：JLPT 历年 N5 - N2 文法真题（公开发布部分）

每个语法点完成后，会在我自己的学习中先验证 2-3 周（用配套的间隔复习清单），确认讲解清晰、例句到位之后再公开发布。

如果你发现某个例句直接来自上述资料而我没标注出处，请提 issue，我会立刻修正。

The lesson structure follows my actual study pace. Example sentences and comparisons reference:

Each grammar point is validated through 2–3 weeks of my own study (using the built-in spaced-repetition checklist) before being published.

If you find an example sentence that directly comes from a referenced source without proper attribution, please file an issue — I'll fix it immediately.
