N5, moving toward N4

You have built a strong foundation in basic conversation and practical daily topics, now moving into more complex expressions like giving directions, wants, and intentions. You're starting to combine learned patterns for more natural speech. Your challenge is refining accuracy with verb forms and particles, especially in new patterns.

Keeps coming up

  • Word choice● still there
    in 4 of 10 lessons

    よん じ です か。 (yon ji desu ka)→よ じ です (yo ji desu)

  • Particle● still there
    in 3 of 10 lessons

    会社 を 行きます。 (kaisha o ikimasu)→かいしゃ に いきます (kaisha ni ikimasu)

  • Verb formimproving
    in 3 of 10 lessons

    えいが を 見ます でした。 (eiga o mimasu deshita)→えいが を みました (eiga o mimashita)

Working on now

  1. 1Using the correct particles (で de, に ni, を o) in sentences about location and direction
  2. 2Mastering verb forms for past, negative, te-form, and たい (tai) / つもり (tsumori) structures
  3. 3Describing preferences, plans, and wants in everyday contexts
  4. 4Conversational skills for practical situations like shopping, eating out, and giving directions

Getting better

  • Your use of polite request structures like て ください (te kudasai) has become more natural and accurate by lesson 7.
  • You now form past and negative verb/adjective sentences correctly, as shown in lessons 5 and 6.
  • You handle sequencing and describing routines smoothly, linking actions with それから (sorekara) and the て-form.

Bring to your next lesson

  • Ask your teacher for more focused practice distinguishing で (de) and に (ni) when talking about locations and directions in sentences.
  • Try to make several sentences using たい (tai) and つもり (tsumori) together—ask the teacher for feedback on the nuances.
  • Start your next class by sharing a recent shopping or restaurant experience in Japanese, using new counters like まい (mai) and ぞく (zoku).

Grammar densityMedium · 6 vocabulary items

We spent the hour on contrast — although, even though, though — and then took it into the restaurant scene you asked for. You reached for although three times unprompted, and put it in the right half of the sentence twice.

The corrections below are nearly all about where the clause sits: although opens one of the two halves, it never stands between them the way but does. Worth a slow read before the homework.

Main corrections

The food was expensive, although. → Although the food was expensive, we stayed.
although joins two halves — only though can be left at the end of a sentence

I am agree with you. → I agree with you.
agree is a verb on its own in English, so it takes no am

We are living here since 2019. → We have been living here since 2019.
since + a starting point takes the present perfect, not the present

Can you explain me the bill? → Could you explain the bill to me?
explain never takes the person straight after it — the thing first, then to me

1. Although: two ideas, one sentence

We started from the sentences you wrote last week and joined them up, one pair at a time.

  • although — in spite of the fact that
  • even though — a stronger although — when the contrast is a surprise
  • though — the same, and the only one that can sit at the end

Although the restaurant was full, they found us a table.

Contrast first, result second — the order that sounds most natural.

Pattern: Although + [clause], [clause].

Note: although and but do the same job, so one sentence never needs both.

  • the bill — what you pay at the end of a mealA2
  • to book a table — to reserve a table in advanceA2
  • to be worth it — good enough to justify the cost or the effortB2

Homework

  • Write five sentences about your week using although, and one with even though.
  • Read the six words out loud twice. The stress on although lands on the second half: al-THOUGH.

What to take from this one

You caught two of your own mistakes today before I said anything — that is new. Next lesson we take the same contrast into writing: a short review of somewhere you liked but would not go back to.

Recap, corrections, vocabulary, flashcards, practice tests and every chart — all of it built from the recording, none of it typed.

How it works

Three things, once.

1

Add the recorder to Chrome

A small extension. It records your microphone and the lesson tab as two separate tracks — which is what makes it possible to tell your voice from your teacher's.

2

Press record when the lesson starts

Wherever the lesson happens: Zoom in a tab, Meet, Preply, italki. Nothing joins the call and nothing shows up on your teacher's screen.

3

Read it a few minutes later

The hour comes back written up — what you covered, the words that came up, the mistakes worth fixing, and how much of the talking was actually you.

Recording needs Google Chrome

The recorder is a Chrome extension — free, one click from the Web Store, on Mac, Windows or Linux. Not Safari, not Firefox. Your lesson can happen anywhere, as long as it happens in a Chrome tab. Add to Chrome →

📱

Reading it works on your phone

Write-ups, vocabulary, flashcards and progress open in any phone browser, no app to install. Only the recording needs a computer, because a phone browser cannot capture a call tab.

Every word that came up, and cards built from them

With its reading, its meaning and the lesson it came from. You revise what you were actually taught.

Your mistakes, quoted back

In your own words, exactly as you said them, with the correction beside it. A correction you cannot recognise is just grammar advice.

Proof you are improving

How much of the hour you spoke, how fast, how long before you answered — measured from the recording, not guessed.

Yours, and only yours

A separate account on a separate database from the teacher product. Nobody can be given access, because there are no teacher accounts in it at all.

Languages

Is yours in there?

Type the language you are learning. Twenty-seven of them come back written up, with the vocabulary and the corrections already done.

Set once, when you make your journal.

Questions

Before you start

Does it work for group lessons?

No. Lesson Journal is built for one-to-one lessons: you and one teacher. It records your microphone and the call as two tracks, so in a group class the other students share your teacher's track and the write-up cannot tell them apart.

Which lessons can I record?

Any lesson that happens in a Chrome tab: Zoom in the browser, Google Meet, Preply, italki. Nothing joins the call and nothing shows on your teacher's screen.

Do I need a computer?

To record, yes: Google Chrome on a Mac, Windows or Linux computer. Your write-ups, vocabulary and flashcards open on any phone.

Does my teacher need to do anything?

No, there is nothing for them to install or set up. Do tell them you are recording, and ask first.

My teacher already uses Lesson Studio. Do I need this?

No. Their plan covers your portal, and your recaps already arrive there.

Does your teacher already use Lesson Studio?

Then you don't need this one. They send you an invite link, you pick your own password, and the write-ups arrive in a portal with their name on it — recorded and checked by them, and covered by what they already pay. Different product, same idea.
