Unit 54Phase P · Conditionals

When it happens automatically

100%always

Whenever A, B follows — every single time, and nobody decides it.

まがると、えきが

ふつうplain form

The part before と stays plain non-past, even about the past.

ふると

✕ おねがいthe catch

No もし, and no requests or invitations after it. Use たら instead.

✕ まがると、〜て

えきは どこですか。

みぎに まがると、 えきが あります。

Step 1

〜と

it just happens

Japanese has four different words for “if”, and English has one — so the whole of Phase P is really about picking the right one. Start with , the one with the sharpest rule: it's 100%. Turn right and the station is simply there — every single time. 🔊 Tap to hear.

ふつうけいplain non-past
+
whenever
+
けっかthe result

Plain non-past + と — “whenever A, B happens”. The useful way to hold on to this one: と is 100%. Turn right and the station is simply there; press the button and the train simply stops. It happens every single time, and nobody chooses it. That one idea explains the rest of this unit — because a もし is never 100%, と can't carry one. The part before と stays plain non-past, even when the sentence is about the past.

Step 2

と の あとに おねがいは ✕

the one rule to remember

Now the rule that decides everything. Because the result is automatic, nothing that depends on someone's will can follow と — no 〜てください, no 〜ませんか, no 〜ましょう. When you need one of those, reach for 〜たら instead. 🔊 Tap to hear.

Need 〜たら again? → Unit 19 introduced it →

〜とautomatic only
〜たらanything can follow

Here's the catch, and it's the whole reason 〜と feels different from the others. Because the result is automatic, nothing that depends on somebody's will can follow it — no requests (〜てください), no invitations (〜ませんか), no “let's” (〜ましょう), no “I want to”. When you need one of those, switch to 〜たら from Unit 19. It carries the same “if / when”, and anything can follow it.

Step 3

クイズ

と or たら?

Six questions. Watch what comes after the comma — if it's a request, と is out.
