Shin Kanzen Master or So-matome: which N2 series should you buy?

The two standard JLPT series solve different problems. Decide by your runway, not by reviews.

Verdict

If you have enough time, choose Shin Kanzen Master. If the exam is within about eight weeks, or you still want English explanations, choose So-matome — a finished easy book beats an abandoned hard one. And whichever side you take: vocabulary and kanji are So-matome's to win.

Shin Kanzen Master

新完全マスター

3A Corporation · 5 volumes · ¥1,200–1,600 + tax each

The rigorous option. All-Japanese explanations, exam-mirroring formats, and enough depth that teachers assign it as a course text. It assumes you'll do the work — and pays that trust back in points.

Nihongo So-matome

日本語総まとめ

Ask Publishing · 5 volumes · ¥1,200–1,500 + tax each

The sustainable option. Each volume is a daily calendar — two pages a day, finished in six to eight weeks — with translations throughout. It trades depth for momentum, deliberately.

The differences that matter

	Shin Kanzen Master	So-matome
Workload	High. Dense B5 volumes of 100–210 pages, no filler.	Low by design. Two pages a day; 123–185 pages per volume.
Difficulty	At or slightly above real exam level.	Slightly below exam level — a ramp, not a wall.
Explanations	Explains why each answer is right, entirely in Japanese.	Brief notes with translations; shows the what more than the why.
Language support	Japanese only.	English on every page, plus Chinese/Korean or Vietnamese depending on printing.
Coverage	Effectively complete for the level.	Frequency-ranked highlights; deliberately not exhaustive.
Self-study fit	Needs discipline and a solid N3 foundation.	Very easy to sustain — the calendar format does the pacing for you.
Time per volume	10–12 weeks at about an hour a day.	6–8 weeks — the schedule is printed on the cover.

Volume by volume

01GrammarAdvantage — Shin Kanzen Master
211 pages vs 170, and the difference is all explanation depth. So-matome tells you a pattern exists; Shin Kanzen teaches you to use it.
02ReadingAdvantage — Shin Kanzen Master
The clearest gap in the whole matchup. Real exam-length passages and answer-elimination technique against a six-week digest.
03ListeningAdvantage — Shin Kanzen Master
Closer than the others. So-matome's 2024 revision is current and pleasant; Shin Kanzen still trains prediction and note-taking harder.
04VocabularyAdvantage — So-matome
Memorization wants a daily calendar and translations, not rigor. This is where So-matome's format is simply the right tool.
05KanjiAdvantage — So-matome
Same logic as vocabulary. Two friendly pages a day beats a drill book you quietly abandon in week three.

Choose Shin Kanzen Master if

You have three months or more before the exam
You can already read a Japanese-only explanation
Reading is your weakest or most important section
You failed N2 before and need the score, not the ritual

Choose So-matome if

The exam is six to eight weeks away
You want English support on every page
You need a habit you'll actually keep — pacing matters more than depth
You're buying vocabulary or kanji volumes (So-matome wins these outright)

The sets, priced

The standard Shin Kanzen Master core set — Grammar, Reading, Listening — comes to ¥4,200 + tax. The equivalent So-matome run lands in the same range. Either way, add the ¥700 Official Practice Workbook for a timed rehearsal, and skip the vocabulary and kanji volumes unless one of those is genuinely your weak point.
