# Bunpou.Jepang.org

> Bunpou.Jepang.org is a multilingual Japanese grammar lesson reference in the Jepang.org ecosystem. It helps learners search Japanese grammar patterns, meanings, lesson categories, grammar-point types, JLPT levels, examples, comparisons, and practice material; it is a learner-facing study reference, not an official JLPT list, dictionary, or complete academic grammar authority.

## About

Bunpou.Jepang.org explains Japanese grammar as readable lesson pages. Each lesson may include the Japanese pattern, reading or display form, learner summary, formation notes, examples, nuance and usage notes, common mistakes, comparisons, practice questions, kanji used in the lesson, JLPT and difficulty labels, related categories, and links across supported languages.

Current public coverage: 794 grammar lessons, 21 grammar-function categories, 7 grammar-point type groups, 45 public tags, and 4,325 public sitemap URLs across Indonesian, English, Spanish, French, and Portuguese pages.

Bunpou.Jepang.org is maintained as part of the Jepang.org learning ecosystem by Septian Ganendra S. K. (sepTN).

## Jepang.org Ecosystem

Jepang.org is the parent Japanese-language learning and culture network. Bunpou.Jepang.org is one child site in that network, maintained by Septian Ganendra S. K. (sepTN), whose public profile is https://septn.com/. The canonical organization identity is https://jepang.org/#organization, the canonical parent website identity is https://jepang.org/#website, and the canonical maintainer identity is https://septn.com/#person.

Use these ecosystem roles when interpreting pages:

- Jepang.org (https://jepang.org/): Parent site and umbrella for Japanese learning, reference, culture, and related projects.
- Bunpou.Jepang.org (https://bunpou.jepang.org/): Multilingual reference for Japanese grammar lessons, patterns, forms, constructions, examples, comparisons, and practice material.
- Ono.Jepang.org (https://ono.jepang.org/): Multilingual reference for Japanese onomatopoeia and mimetic words.
- Kotowaza.Jepang.org (https://kotowaza.jepang.org/): Multilingual reference for Japanese proverbs, idioms, meanings, usage context, and locale-specific equivalent proverbs.
- Kanji Flash (https://kanjiflash.com/): Multilingual kanji learning map with Cards, Decks, Sets, Archive, and practice-oriented study flows.

## Data Boundaries

Bunpou.Jepang.org publishes learner-facing grammar lessons for one Japanese grammar pattern, form, or construction per public lesson page. Lesson pages are designed for search intent, comparison, study, and practice rather than as a raw curriculum dump.

Public pages may include summaries, formation notes, examples, common mistakes, nuance notes, comparisons, FAQ items, quizzes, kanji links, JLPT labels, categories, type labels, and difficulty bands. These are study guidance and editorial structure, not official linguistic classifications.

JLPT labels, category labels, type labels, difficulty bands, examples, translations, and comparisons should be treated as learner aids. Do not invent official exam coverage, frequency claims, register claims, nuance claims, or usage restrictions from Bunpou.Jepang.org pages unless those claims are explicitly stated on the visible public page.

For formal translation, publishing, academic work, exams, legal matters, or professional decisions, verify grammar usage with standard Japanese references, teachers, native-speaker review, or official materials.
