Nihongo So-matome (日本語総まとめ, “Japanese Complete Summary”) is a series of JLPT preparation books published by ASK Publishing, covering all five JLPT levels (N1–N5) across separate volumes for grammar, vocabulary, kanji, reading comprehension, and listening comprehension. The series is structured around a six-week study schedule, presenting content in small daily units designed for systematic review rather than first-time introduction of grammar or vocabulary.
Programs and Structure
Each Nihongo So-matome volume targets a specific JLPT level and skill:
Volume Organization
Each book is divided into six weeks of study, with approximately five daily lessons per week. Each daily lesson is two pages — a left page presenting the target grammar points, vocabulary, or kanji in context, and a right page with practice questions. Weekly review sections and a final practice test appear at week intervals.
Grammar Volumes (N1–N5)
Present grammar patterns at the target level with example sentences, usage notes, and comparison of similar patterns. N1 and N2 grammar volumes are the most frequently used, as they cover advanced grammar that is poorly represented in general-purpose textbooks.
Vocabulary Volumes (N1–N5)
Present vocabulary organized by theme and frequency, with kanji readings, example sentences, and brief review drills. Designed as a rapid review tool rather than a first-exposure vocabulary course.
Kanji Volumes (N1–N5)
Organized by radical, stroke count, or semantic category depending on level, with reading practice in context. More compact than dedicated kanji learning systems like Heisig’s Remember the Kanji.
Reading and Listening Volumes (N1–N2)
Practice reading passages and listening exercises formatted to match JLPT question types. Reading volumes at N1–N2 are commonly used alongside authentic reading practice.
Six-Week Format
The six-week structure is designed for learners doing final preparation before a JLPT sitting. It is not intended for learners who have not yet acquired the underlying grammar or vocabulary — it reviews and consolidates rather than teaches from scratch.
History
Nihongo So-matome was published by ASK Publishing starting in the mid-2000s and expanded significantly with the JLPT format revision in 2010, which restructured the test from four levels (4–1) to five levels (N5–N1) and changed the grammar, vocabulary, and reading question formats. The series was updated and expanded to cover the new N1–N5 framework.
ASK Publishing positioned So-matome as a lighter, more accessible JLPT preparation series compared to earlier JLPT prep books, which tended to be dense reference volumes. The two-pages-per-day structure was explicitly designed to reduce learner anxiety and provide a manageable daily study habit for working adults and busy students preparing for JLPT.
The series became one of the two dominant JLPT preparation series in the Japanese learning market globally, alongside the Kanzen Master (完全マスター) series by 3A Corporation.
Practical Application
Nihongo So-matome is most effective when used as a consolidation and test-format familiarization tool in the final six to twelve weeks before a JLPT sitting. Learners who have studied Japanese to approximately the level below their target (e.g., a learner who has completed solid N3-level study attempting N2) use So-matome to review grammar patterns systematically, identify gaps, and practice reading the test’s question phrasing.
The grammar volumes are the most commonly recommended among self-study learners, as the N2 and N1 grammar points are not well covered by most general-purpose textbooks. Many learners use Tobira or similar for general intermediate study, then shift to So-matome grammar for targeted JLPT preparation.
Learners commonly pair So-matome with Kanzen Master for more thorough coverage — So-matome for daily review accessibility, Kanzen Master for depth of grammar explanation on difficult points.
Completing all So-matome volumes for a given level (grammar + vocabulary + kanji + reading + listening) takes approximately 30 weeks if done consecutively, though most learners prioritize grammar and vocabulary.
Common Misconceptions
A common misconception is that So-matome alone is sufficient to pass JLPT N1 or N2 from an intermediate foundation. The series assumes pre-existing knowledge at a level just below the target; learners who have not yet reached the prerequisite level find the material too dense to absorb as new input. It is a review and consolidation tool, not a primary learning curriculum.
Another misconception is that So-matome and Kanzen Master are equivalent alternatives. In practice, Kanzen Master is considered more thorough and demanding, with more detailed grammar explanations and harder practice questions; So-matome is more accessible and paced for daily habit formation. Many serious JLPT candidates use both.
Some learners also assume that So-matome’s six-week timeline is a guaranteed JLPT pass plan. The six weeks covers review of the key grammar, vocabulary, and kanji points, but reading speed, listening comprehension, and strategic test-taking skills require longer development.
Social Media Sentiment
On r/LearnJapanese and JLPT-focused communities, Nihongo So-matome and Kanzen Master are the two most discussed JLPT preparation series. So-matome is typically recommended to learners who want a structured, manageable daily study format; Kanzen Master to learners who want the most thorough preparation and can handle denser material.
A recurring discussion point is which to use for N2 grammar specifically — the N2 grammar volume is considered by many learners the most useful single JLPT prep book available, particularly for consolidating the large and varied N2 grammar pattern list.
Learners preparing for N1 frequently recommend both series together, noting that neither alone covers all points that appear on the actual test with sufficient depth.

Summary: The primary source for the Nihongo So-matome series; the N2 grammar volume exemplifies the series format — six weeks of daily two-page lessons covering JLPT N2 grammar patterns with example sentences, usage notes, and practice questions; widely used by learners preparing for JLPT N2 as a systematic grammar review tool in the final weeks before the examination. - Takashima, H., & Ellis, R. (1999). “Output enhancement and the acquisition of the past tense.” In R. Ellis (Ed.), Learning a Second Language Through Interaction (pp. 173–188). John Benjamins.
Summary: Examines the role of structured output practice and form-focused instruction in grammar acquisition, providing a theoretical basis for understanding why spaced review formats like So-matome’s daily lesson structure support retention of grammatical forms; the spaced, repeated exposure to grammar patterns in test-prep contexts is consistent with evidence on form-focused instruction contributing to explicit knowledge consolidation.
