Shin Kanzen Master or So-matome: which N1 series should you buy?
The famous decision at its final level — where one series stops translating, and the other stops being enough on its own.
Verdict
With months of runway and the ability to work from all-Japanese explanations, choose Shin Kanzen Master — it's the set N1 passers credit. Choose So-matome if the exam is about eight weeks out or you want translated support — but at N1, treat its calendar as the review layer and let the official workbook, sat timed, tell you whether it was enough. Many learners end up using them as phases, not rivals.

The differences that matter
| Shin Kanzen Master | So-matome | |
|---|---|---|
| Approach | The same three-part exam-mirroring course as the lower levels: question formats introduced, then ability-building by format, then a mock section. | A printed calendar: eight weeks, two pages a day, with the grammar portioned into daily servings and a booklet for checking. |
| Language support | None. The N1 volumes are entirely in Japanese — unlike N3, where this series translates its explanations, here it gives you nothing. | English, Chinese and Korean glosses under the examples, plus downloadable example-sentence audio in the revised edition. |
| Vintage | Written for the 2010 exam reform (2010–2011) and unchanged since — the content matches the current format, but the audio ships on CD. | The whole N1 set was re-issued 2022–2024 as revised and expanded editions with modern audio delivery. |
| Explanations | Near-identical forms grouped and contrasted the way the exam tests them — the treatment passers credit most at this level. | Daily portions with glossed examples; the series deliberately skips subtle differences because the exam, in its reading of it, doesn't reward them. |
| Distance to the exam | The reading volume trains against exam-length N1 passages and ends in a full mock reading section. | The reading volume is deliberately lighter than the exam — which is both its point and its limit. |
| Pacing | No built-in schedule — the recurring complaint across the series: you plan the weeks yourself. | The schedule is the product: eight weeks, printed on the book. |
What changes at N1
Two axes move at the top level. First, the translation gate closes completely: at N3 Shin Kanzen translates its explanations and at N2 it doesn't but the grammar is nearer to reach — at N1 the set is all-Japanese with no concessions, so So-matome's three-language glosses stop being a comfort feature and become the only translated route through this decision (with TRY! N1 as the gentler translated on-ramp — see the N1 guide). Second, an axis that didn't exist at the lower levels: age. Shin Kanzen's N1 set dates to 2010–2011, written for the exam reform that created the current format and untouched since; So-matome's N1 set was rebuilt in 2022–2024 with audio you can actually download. The exam hasn't changed, so the old set isn't wrong — but one series is a living product and the other is a fixed standard, and which of those you'd rather study from is a real preference, not a technicality.
Choose Shin Kanzen Master if
- You have three months or more before the exam
- All-Japanese explanations are fine — at this level they're also practice
- Reading stamina is the section you fear — its reading volume ends in a full mock
- You want the set the pass reports keep crediting
Choose So-matome if
- The exam is about eight weeks away — the calendar fits
- You want English, Chinese or Korean under the examples
- You're reviewing N1 grammar you've met before, not learning it cold
- Current editions and downloadable audio matter to you
