Why the usual numbers mislead
The numbers most learners watch are chosen because they are easy to count, not because they reflect ability. A streak counts days. A card total counts reviews. A level label counts what you could recognise on one morning under exam conditions. All three can climb steadily during a stretch in which your spoken Japanese does not change at all, and that mismatch is what makes people feel they are working hard for nothing.
Useful measures share three features. They are repeatable in the same form, so two runs are comparable. They test production or unrehearsed comprehension rather than recall of studied items. And they are cheap enough that you will actually run them, because a measure that needs an appointment gets skipped in exactly the months you most need the data.
The four measures at a glance
| Measure | How to run it | How often |
|---|---|---|
| Fixed monthly recording | Same prompt every time, two minutes, no notes, no second take; save with the date | Monthly |
| Can-do checklist | Mark each task done unaided, done with help, or not yet; only tasks, never topics | Every three months |
| Timed reading page | Read a fresh page of similar difficulty for five minutes, count lines and unknown words | Every three months |
| Listening check | Play unfamiliar audio once at normal speed, then summarise three points aloud | Monthly |
Run all four and they cover the four skills that actually move at different speeds. The recording shows fluency and range, the can-do list shows usable ability, the reading page shows decoding speed, and the listening check shows comprehension of speech you have not tidied up in advance.
Measure one: the fixed monthly recording
This is the single most informative thing on the list and it costs two minutes. Choose one prompt and keep it for a year. Record without notes, without pausing to think of a word, and without a second attempt, because a second attempt measures preparation rather than fluency. Save the file with the date and do not listen back immediately.
A month later, record again on the same prompt and play the two files one after the other. You are listening for four things: total words said in two minutes, the length of your pauses, whether you self-corrected and carried on, and whether any sentence contains a structure the older recording never attempted. Those four move long before any level label does.

| 最近の一週間について、二分間話してください。 | Saikin no isshūkan ni tsuite, nifunkan hanashite kudasai. | Prompt: Talk for two minutes about your past week. |
| 今日は九月一日です。三回目の録音です。 | Kyō wa kugatsu tsuitachi desu. Sankai-me no rokuon desu. | Today is the first of September. This is my third recording. |
| 先週は忙しかったです。特に水曜日が大変でした。 | Senshū wa isogashikatta desu. Toku ni suiyōbi ga taihen deshita. | Last week was busy. Wednesday in particular was hard. |
| 理由は、会議が三つ重なったからです。 | Riyū wa, kaigi ga mittsu kasanatta kara desu. | The reason is that three meetings fell on the same day. |
| そのあと、友達と食事に行きました。 | Sono ato, tomodachi to shokuji ni ikimashita. | After that, I went out for a meal with a friend. |
| 全体的に、いい一週間だったと思います。 | Zentaiteki ni, ii isshūkan datta to omoimasu. | Overall, I think it was a good week. |
| 来月も同じ質問で録音します。 | Raigetsu mo onaji shitsumon de rokuon shimasu. | Next month I will record on the same question again. |
Other prompts worth fixing for a year
One prompt is enough, but a set of three lets you rotate without losing comparability, as long as each prompt is compared only with its own earlier recordings. Choose prompts that require narration, explanation, and opinion, since those three demand different grammar and a learner is rarely equally strong in all of them.
| Japanese | Romaji | Meaning |
|---|---|---|
| 自分の仕事か勉強について説明してください。 | Jibun no shigoto ka benkyō ni tsuite setsumei shite kudasai. | Prompt: Explain your work or your studies. |
| 最近困ったことと、どう解決したかを話してください。 | Saikin komatta koto to, dō kaiketsu shita ka o hanashite kudasai. | Prompt: Talk about a recent problem and how you solved it. |
| 住んでいる町のいいところと不便なところを教えてください。 | Sunde iru machi no ii tokoro to fuben na tokoro o oshiete kudasai. | Prompt: Tell me the good and inconvenient points of the town you live in. |
| 十年後、自分は何をしていると思いますか。 | Jūnen go, jibun wa nani o shite iru to omoimasu ka. | Prompt: What do you think you will be doing in ten years? |
Measure two: a can-do list of tasks
Most syllabuses are lists of topics, and a topic cannot be passed or failed. A can-do list is a list of tasks with an outcome: something either happened or it did not. Write yours from situations you genuinely encounter or expect to, not from a textbook table of contents, because a task you will never perform gives you no useful signal when it stays unticked.
Mark each item three ways: done unaided, done with help or repetition, and not yet. The interesting movement is usually from the middle column to the first, and that shift is invisible to any level label. Review the list every three months and rewrite items that have become too easy.
| Japanese | Romaji | Meaning |
|---|---|---|
| 電話で予約を変更できます。 | Denwa de yoyaku o henkō dekimasu. | I can change a booking over the phone. |
| 道に迷ったとき、知らない人に助けを求められます。 | Michi ni mayotta toki, shiranai hito ni tasuke o motomeraremasu. | When lost, I can ask a stranger for help. |
| 病院で症状を三文で説明できます。 | Byōin de shōjō o sanbun de setsumei dekimasu. | I can explain my symptoms at a clinic in three sentences. |
| 会議で自分の意見を理由付きで言えます。 | Kaigi de jibun no iken o riyū-tsuki de iemasu. | I can state my opinion with a reason in a meeting. |
| 買った物を返品したい理由を説明できます。 | Katta mono o henpin shitai riyū o setsumei dekimasu. | I can explain why I want to return something I bought. |
| 初対面の人と五分間雑談ができます。 | Shotaimen no hito to gofunkan zatsudan ga dekimasu. | I can make small talk with someone I have just met for five minutes. |
| 予定の変更を、メールではなく口頭で伝えられます。 | Yotei no henkō o, mēru de wa naku kōtō de tsutaeraremasu. | I can pass on a schedule change by speaking rather than by email. |
| 聞き取れなかったとき、言い換えをお願いできます。 | Kikitorenakatta toki, iikae o onegai dekimasu. | When I miss something, I can ask for it to be rephrased. |
Notice that every item names a situation and an action. Compare that with a topic heading such as travel, which you can neither complete nor fail. If you cannot picture yourself doing the item this month, it belongs on a later list.
Measure three: the timed reading page
Reading speed is a good proxy for how automatic your grammar and vocabulary have become, and it is easy to measure without a test. Take a fresh page of roughly the level you normally read, set five minutes, and read for meaning rather than for perfection. Count how far you got and how many words you did not know.
Do not reuse the same page. The point is fresh material of similar difficulty, because a page you have read before measures memory. If your line count rises while unknown words stay flat, your processing is getting faster. If unknown words fall but the line count does not move, you are learning vocabulary without building speed, and that usually means more reading volume is needed rather than more study.

|---|---|---|
| この記事を五分間で何行読めるか数えます。 | Kono kiji o gofunkan de nangyō yomeru ka kazoemasu. | I will count how many lines of this article I can read in five minutes. |
| 分からない言葉に線を引きます。 | Wakaranai kotoba ni sen o hikimasu. | I underline the words I do not know. |
| 辞書はあとで使います。今は止まりません。 | Jisho wa ato de tsukaimasu. Ima wa tomarimasen. | I will use the dictionary later. For now I do not stop. |
| 前回より三行多く読めました。 | Zenkai yori sangyō ōku yomemashita. | I read three lines more than last time. |
Measure four: the listening check
Listening is where learners most often overestimate themselves, because familiar material replays a memory rather than testing comprehension. Use audio you have never heard, at normal speed, once. Then, without replaying it, say three points aloud in Japanese. Saying them aloud matters: if you can only summarise in your own language, you understood the content but cannot yet handle it in Japanese.
Score it plainly. Three points with confidence is a pass, one point is a partial, and losing the thread entirely means the material was too hard for measurement purposes. Keep a note of what defeated you, since numbers, names, and fast connected speech fail for different reasons and need different practice.
| Japanese | Romaji | Meaning |
|---|---|---|
| 一回だけ聞いて、要点を三つ言います。 | Ikkai dake kiite, yōten o mittsu iimasu. | I listen once only, then say three main points. |
| だいたい分かりましたが、細かい数字は聞き取れませんでした。 | Daitai wakarimashita ga, komakai sūji wa kikitoremasen deshita. | I understood roughly, but I could not catch the exact numbers. |
| 名前と場所は分かりましたが、理由が分かりませんでした。 | Namae to basho wa wakarimashita ga, riyū ga wakarimasen deshita. | I got the name and the place, but not the reason. |
| 速さのせいか、単語のせいか、はっきりさせます。 | Hayasa no sei ka, tango no sei ka, hakkiri sasemasu. | I will work out whether it was the speed or the vocabulary. |
Keep a corrections log and watch errors disappear
A corrections log is the cheapest long-term measure there is. After each conversation, write down at most three corrections in the form wrong sentence, corrected sentence, one word for the pattern. Three is deliberate: a full list is never reread, while three fit in your head for the next session.
The measure is not the number of entries but which patterns stop reappearing. Every month, scan the log and mark any pattern that has not shown up in four weeks as retired. Watching a particle error you made weekly in March vanish by June is far more convincing evidence than any score, and it also tells you exactly what is still open.
| Japanese | Romaji | Meaning |
|---|---|---|
| 今の話で、不自然なところはありましたか。 | Ima no hanashi de, fushizen na tokoro wa arimashita ka. | Was there anything unnatural in what I just said? |
| 同じ間違いを前にもしましたか。 | Onaji machigai o mae ni mo shimashita ka. | Have I made the same mistake before? |
| 今日の間違いを三つに絞ってください。 | Kyō no machigai o mittsu ni shibotte kudasai. | Please narrow today's mistakes down to three. |
| 助詞の間違いは減りましたが、敬語はまだ苦手です。 | Joshi no machigai wa herimashita ga, keigo wa mada nigate desu. | My particle mistakes have decreased, but I am still weak at honorific language. |
| この間違いは先月から出ていません。 | Kono machigai wa sengetsu kara dete imasen. | This mistake has not appeared since last month. |
The delay between input and visible output
Input and output improve on different schedules, and confusing the two is a common reason learners abandon a method that was working. A month of heavier listening usually shows up first as easier comprehension, then later as new phrases appearing unbidden in your own speech. The gap between those two moments can be weeks, so a recording taken shortly after an input change often shows nothing.
Plan for the lag. Measure comprehension monthly and speech monthly, but judge an input change on the listening check first and only look for it in the recording a couple of months later. Expect one more oddity: when you start using new structures, your accuracy can dip because you are attempting harder sentences. Falling accuracy alongside rising range is progress, not decline.

| 三か月前の録音と比べると、間が短くなりました。 | Sankagetsu mae no rokuon to kuraberu to, ma ga mijikaku narimashita. | Compared with the recording from three months ago, my pauses are shorter. |
| 数字は上がっていませんが、内容は前より詳しいです。 | Sūji wa agatte imasen ga, naiyō wa mae yori kuwashii desu. | The numbers have not gone up, but the content is more detailed than before. |
| 聞くのは楽になりましたが、話すのはまだです。 | Kiku no wa raku ni narimashita ga, hanasu no wa mada desu. | Listening has got easier, but speaking has not yet. |
| 新しい言い方を使ったので、間違いが増えました。 | Atarashii iikata o tsukatta node, machigai ga fuemashita. | I used new expressions, so my mistakes increased. |
What to change when a measure stops moving
A flat measure is information, not a verdict. Check the measure itself first: a can-do list you have outgrown, a reading page you half remember, or a prompt you have effectively rehearsed will all sit still no matter how much you improve. Refresh the instrument before you rebuild the routine.
If the measure is still honest and still flat, change one thing in your practice and set an end date for the trial. The dedicated post on breaking a Japanese plateau goes through the usual causes and the interventions that match them. Whatever you change, keep measuring in the same way, because a new measurement method resets your history and you lose the only comparison you had.
- Recording flat: force longer turns and ban the phrases you use to end them early.
- Can-do list flat: rewrite it from this month's real situations, then retest.
- Reading page flat in speed: increase volume of easy reading rather than adding harder texts.
- Listening check flat: change the source rather than the level, since one speaker or format can be the obstacle.
- Everything flat: reduce the total time and spend all of it on unrehearsed speech for three weeks.
