Editorial Policy

Bunpou.Jepang.org focuses on Japanese grammar patterns, forms, and constructions. Each lesson should answer one learner question clearly: what the pattern means, how it forms, where it sounds natural, and which nearby forms can cause confusion.

The site supports study. It does not replace a teacher, textbook, official exam source, academic reference, professional translator, or language certificate.

Lessons start from the Bunpou.Jepang.org curriculum and reviewed lesson materials. Editors use those materials to shape pages for learners.

Claims about meaning, formation, register, nuance, JLPT level, examples, and comparisons must stay within the available material. We avoid unsupported claims about origin, frequency, official exam coverage, or one correct use for every context.

A reader should be able to open a lesson and understand the grammar point without reading another page first. A complete lesson may include meaning, formation, examples, nuance, common mistakes, comparisons, practice, tags, and related lessons.

Categories and types help readers browse by grammar function and lesson form. JLPT and difficulty levels help with study planning.

Japanese examples, translations, mini practice, comparison notes, and audio buttons are learning aids. They help readers test a pattern in a simple context.

Examples are not corpus citations. Practice results are not grades, certificates, or proof of Japanese ability. Audio uses browser features when available, and playback can differ by device.

Bunpou.Jepang.org may use writing, localization, and review tools to prepare lessons and public pages. Editors still decide what belongs on the page and keep claims within the available evidence.

The public site serves reviewed pages. It does not generate new grammar explanations during a reader visit, and search results come from the existing lesson list.

Indonesian, Spanish, French, and Portuguese pages should keep the same claims while reading naturally in each language.

Localized pages must keep page titles, descriptions, buttons, links, and body copy in the page language. Japanese grammar examples stay in Japanese because they are the subject being studied.

Mistakes can appear in explanations, examples, translations, readings, romanization, practice, labels, links, page titles, or layout. Reader reports help us correct them.

Send corrections through Corrections or email [email protected]. Reports with a URL, the affected text, the problem, and a suggested fix are easier to review.
