もしもし ごめん, 今日帰らなくなっちゃって
こっちは大丈夫, そっちも雨?
Introduction to Japanese Phone Conversation
Today we’re learning natural Japanese telephone conversation phrases. These expressions demonstrate casual spoken Japanese with contractions and colloquialisms that are essential for everyday communication. For JLPT N4-N3 students, understanding these casual forms is crucial for comprehending real-life Japanese conversations, especially the ちゃう/じゃう contraction of てしまう.
Opening: もしもし ごめん
Understanding もしもし
もしもし is the standard Japanese telephone greeting, equivalent to “hello” when answering or making a phone call. It’s used exclusively for telephone conversations and is one of the first things you’ll hear on any Japanese phone call.
Translation: Hello (on the phone), sorry
The Origin of もしもし
Etymology:
もしもし comes from the verb 申す (もうす), a humble form of 言う (to say). Originally, telephone operators would say もし申します (moshi moushimasu) meaning “excuse me, I’m speaking.” Over time, this was shortened and repeated as もしもし. The repetition helps ensure the connection is clear and both parties can hear each other.
When and How to Use もしもし
Usage contexts:
When answering the phone: もしもし
When making a call: もしもし、田中ですが… (Hello, this is Tanaka…)
When checking if someone is still there: もしもし?聞こえる? (Hello? Can you hear me?)
When the connection is bad: もしもし?もしもし? (Hello? Hello?)
Not used for:
Face-to-face greetings (use こんにちは instead)
Video calls (some people use it, but it’s becoming less common)
もしもし ごめん – Starting with an Apology
Following もしもし immediately with ごめん (sorry) sets an apologetic tone. This is common in Japanese phone conversations when you’re about to deliver bad news or cancel plans. The speaker is preemptively apologizing for what they’re about to say.
Similar opening patterns:
もしもし、ごめん – Hello, sorry
もしもし、すみません – Hello, excuse me
もしもし、悪いんだけど – Hello, this is bad but…
もしもし、ちょっと – Hello, um…
もしもし、今大丈夫? – Hello, is now okay?
Main Expression: 今日帰らなくなっちゃって
Word Breakdown
今日 (きょう) – today
帰らなく – not go home (negative stem of 帰る)
なっちゃって – ended up (casual contraction of なってしまって)
Literal vs Natural Translation
Literal meaning: Today ended up not going home
Natural translation: I ended up not being able to come home today / I can’t make it home today / It turned out I can’t come home today
Grammar Point: なる (To Become)
帰らなくなる literally means “become not going home” or “it becomes that (I) don’t go home.” This construction with なる expresses a change in state or situation.
なる pattern with negative verbs:
行かなくなる – Stop going, become not going
食べなくなる – Stop eating
話さなくなる – Stop talking
会わなくなる – Stop meeting
帰らなくなる – Stop going home, become unable to go home
Grammar Point: てしまう (Completion/Regret)
てしまう is added after the て-form of verbs to express that something has been completed, often with nuances of regret, accident, or irreversibility. It’s one of the most common auxiliary verbs in Japanese.
Two main meanings of てしまう:
1. Completion: Something is completely done
食べてしまった – Finished eating (it’s all gone)
2. Regret/Accident: Something unfortunate happened, often unintentionally
忘れてしまった – I forgot (and I regret it)
壊れてしまった – It broke (unfortunately)
The context determines which nuance is stronger.
Grammar Point: ちゃう/じゃう (Casual Contraction)
This is where it gets interesting for spoken Japanese. てしまう is commonly contracted in casual speech:
Contraction rules:
てしまう → ちゃう
でしまう → じゃう
Examples:
食べてしまう → 食べちゃう (end up eating)
忘れてしまう → 忘れちゃう (end up forgetting)
読んでしまう → 読んじゃう (end up reading)
死んでしまう → 死んじゃう (end up dying)
The て/で sound merges with しまう to create this casual, natural-sounding contraction.
Breaking Down なっちゃって
Step-by-step transformation:
1. なる (to become)
2. なって (て-form)
3. なってしまう (ended up becoming)
4. なっちゃう (casual contraction)
5. なっちゃって (て-form of なっちゃう, for connecting/explaining)
帰らなくなってしまって → 帰らなくなっちゃって
Why the て-form Ending?
The sentence ends with て (なっちゃって) rather than completing the thought. This is very common in casual Japanese conversation, especially when explaining or apologizing. The て-form leaves the sentence open, implying “and so…” or “that’s why…” The rest is understood from context.
Common sentence-ending て patterns:
忙しくなっちゃって (I got busy, so…)
遅れちゃって (I’m running late, so…)
忘れちゃって (I forgot, so…)
風邪引いちゃって (I caught a cold, so…)
The implied continuation might be:
ごめん (sorry)
行けない (I can’t go)
連絡できなかった (I couldn’t contact you)
More Examples with ちゃう/じゃう
Everyday usage:
あ、間違えちゃった! – Oh, I made a mistake!
全部食べちゃった – I ate it all
寝坊しちゃって、遅れた – I overslept, so I was late
携帯なくしちゃった – I lost my phone
約束忘れちゃってた – I had forgotten the promise
見ちゃダメ! – Don’t look! (must not look)
やっちゃえ! – Just do it! (go ahead and do it)
Second Part: こっちは大丈夫, そっちも雨?
Word Breakdown
こっち – here, this side, my side
は – topic particle
大丈夫 (だいじょうぶ) – okay, fine, all right
そっち – there, that side, your side
も – also, too
雨 (あめ) – rain
Translation
Translation: Things are okay here/on my end, is it raining there too?
Understanding こっち and そっち
These are casual, contracted forms of demonstrative words indicating location or direction. They’re essential for natural conversation and much more common in speech than their formal counterparts.
The complete demonstrative system:
Formal vs Casual:
こちら → こっち (this side, here, I/we)
そちら → そっち (that side, there, you)
あちら → あっち (that side over there)
どちら → どっち (which side, where)
In phone conversations, こっち means “my location/situation” and そっち means “your location/situation.”
Multiple Meanings of こっち/そっち
Context-dependent meanings:
Physical location:
こっちに来て – Come here
そっち行くよ – I’ll go there
Abstract side/situation:
こっちは準備できた – We’re ready here/on our end
そっちはどう? – How about you?/How are things there?
Direction to turn:
こっちじゃなくて、そっち – Not this way, that way
Preference/choice:
こっちがいい – I prefer this one
そっちにする – I’ll take that one
Understanding 大丈夫
大丈夫 is one of the most versatile words in Japanese, with meanings ranging from “okay” to “fine” to “no problem” to “no thank you.”
Various uses of 大丈夫:
Confirming you’re okay:
大丈夫? – Are you okay?
大丈夫だよ – I’m fine
Saying something is acceptable:
これでも大丈夫? – Is this okay too?
大丈夫です – It’s okay/That’s fine
Declining something politely:
水いる? – Want water?
大丈夫です – I’m good/No thanks
Reassuring someone:
心配しないで、大丈夫 – Don’t worry, it’s okay
The Question: そっちも雨?
This is an extremely casual question structure, common in phone conversations. The full, formal version would be そちらも雨ですか? but in casual speech, particles and copulas are often dropped.
Casual question patterns:
Full formal: そちらも雨ですか?
Dropping copula: そちらも雨?
Casual pronoun: そっちも雨?
More examples:
今日暇? (Are you free today?)
もう食べた? (Did you already eat?)
これ知ってる? (Do you know this?)
あれ誰? (Who’s that?)
そこ駅? (Is that the station?)
The Particle も (Also, Too)
The use of も implies that it’s raining where the speaker is, and they’re asking if it’s also raining where the listener is. This creates a sense of shared experience.
も indicating shared situations:
こっちは雪だよ。そっちも? – It’s snowing here. There too?
私も疲れた – I’m tired too
そっちも混んでる? – Is it crowded there too?
今日も暑い? – Is it hot today too?

Wrong: (meeting someone) もしもし
Correct: こんにちは or other appropriate greeting
もしもし is exclusively for telephone use
Mistake 2: Overusing ちゃう in formal situations
Casual: 忘れちゃいました
Formal: 忘れてしまいました
Use the full てしまう form in polite/formal contexts
Mistake 3: Confusing particles with も
Wrong: そっちは雨? (sounds like “As for there, rain?”)
Correct: そっちも雨? (Is it raining there too?)
The も creates the sense of “also”
Mistake 4: Using こちら/そちら too casually
With friends: こっち使って (Use this)
Formal: こちらをお使いください (Please use this)
Match formality level to context
Key Takeaways for JLPT Students
もしもし is essential telephone vocabulary. While simple, knowing when and how to use it properly is important for practical Japanese.
ちゃう/じゃう contractions are crucial for understanding casual spoken Japanese. This appears frequently in JLPT listening sections and is essential for N4-N3 level students.
こっち/そっち demonstratives are among the most common words in casual conversation. Understanding these contracted forms versus their formal counterparts (こちら/そちら) is important for both production and comprehension.
The casual question structures and sentence-ending て patterns represent natural Japanese that you’ll encounter constantly in real conversations but might not see as much in textbooks.
Cultural Context
Japanese Phone Culture:
Japanese phone etiquette includes several cultural elements visible in our phrases:
Starting with apology: Japanese speakers often apologize preemptively when calling with bad news, showing consideration for the other person’s time and feelings.
Checking on others: Asking そっちも雨? shows concern for the other person’s situation, reflecting the relational nature of Japanese communication.
Indirect explanations: Ending with て-form (帰らなくなっちゃって) leaves things implied rather than stating everything directly, trusting the listener to understand the context.
Wrap-up
Today we explored natural Japanese telephone conversation through two essential phrases. From the ubiquitous もしもし to the complex but common ちゃう contraction, these expressions represent the kind of everyday Japanese that makes you sound natural and fluent.
The 帰らなくなっちゃって construction demonstrates how multiple grammar points combine in natural speech – the negative なる, the regretful てしまう, and the casual contraction ちゃう all working together to express an unfortunate change in plans.
Meanwhile, こっち/そっち and the ultra-casual question そっちも雨? show how Japanese strips away formality in close relationships and urgent situations, creating the quick, efficient communication style of actual phone conversations.
Remember that mastering these casual forms isn’t just about passing JLPT – it’s about being able to participate naturally in everyday Japanese life. Practice listening for these contractions in Japanese media and try incorporating them into your own casual conversations. The more natural your casual Japanese sounds, the more comfortable native speakers will be talking with you.
