Japanese Reading Practice N4: A Casual Letter to a Friend

This is an original casual Japanese letter at JLPT N4 level, written the way friends message each other on LINE: short lines, plain forms and friendly sentence endings. Each line has romaji and an English gloss, followed by notes on casual grammar, comprehension questions and a polite rewrite.

What you need to know

Textbooks teach you to read polite Japanese, but most of what friends actually write to each other is casual. Plain verbs, dropped particles, contractions like 降ってる and explanatory endings like 行ったんだ appear in every chat, and they can make a simple message feel surprisingly hard to read. This text is a letter from Yui in Japan to Maria, a friend who has gone home to Spain. It thanks her for photos, shares news about a ramen shop and a new job, asks about her Japanese and hopes they can meet in summer. The grammar is N4: plain past forms, 〜てる, 〜んだ, 〜たことがない, 〜ことになった, 〜と思う and 〜たらいいね. After the letter you will find word notes, a casual grammar guide, the same key lines in polite Japanese so you can see the difference, three questions with answers and a read-aloud routine that helps casual rhythm sound natural.

Casual writing uses plain forms and often drops を and は

〜てる is the spoken short form of 〜ている

〜んだ explains or shares news with a personal touch

Use casual style only with friends; switch to polite with others

The letter: マリアへ

Yui lives in Japan. Her friend Maria studied in Japan last year and has gone home to Spain. Read the letter once without help.

Casual messages are easier to read aloud than to read silently, because their rhythm is the rhythm of speech. If a line looks strange, say it out loud: 降ってるよ and 聞いてたよ often make sense the moment you hear them. Read the letter first for the four pieces of news, then go back for the details.

Four picture cards: To Maria, How are you, It's been a while, and Thanks for the photos.
Four short lines that open almost every casual message between friends.

Vocabulary notes

Casual messages reuse a small set of friendly words. Once you know them, most chats become much easier to read.

JapaneseRomajiMeaning
久しぶりhisashiburilong time no see, it's been a while
こっちkotchihere, my side (casual こちら)
最近saikinlately, recently
おじさんojisanmiddle-aged man (friendly, not only uncle)
楽しみtanoshimisomething you look forward to
きっとkittosurely, I bet
続けるtsuzukeruto continue, to keep doing
いつかitsukasomeday
連絡するrenraku suruto get in touch, to message
気をつけるki o tsukeruto be careful, to take care

〜へ and 〜より frame the letter: マリアへ, to Maria, and ゆいより, from Yui. They are standard in casual letters, cards and notes. マリアちゃん uses ちゃん, a friendly, affectionate suffix often used for children, girls and close friends; the shop owner uses it because he knew Maria as a regular. Do not add ちゃん to names on your own unless you are sure the relationship allows it.

Grammar notes: how casual Japanese works

The letter is N4 grammar in casual clothes. Each pair below shows a line from the letter and a new example.

JapaneseRomajiMeaning
毎日雨が降ってるよ。Mainichi ame ga futteru yo.From the letter: It's raining every day.
今、ご飯を食べてる。Ima, gohan o tabeteru.I'm eating right now. (casual)
ラーメン屋に行ったんだ。Rāmen'ya ni itta n da.From the letter: I went to the ramen shop, you know.
昨日、財布をなくしたんだ。Kinō, saifu o nakushita n da.I lost my wallet yesterday, you see.
スペインに行ったことがないから、いつか行ってみたいな。Supein ni itta koto ga nai kara, itsuka itte mitai na.From the letter: I've never been to Spain, so I'd love to go.
すしを食べたことがない。Sushi o tabeta koto ga nai.I've never eaten sushi. (casual)
夏休みに会えたらいいね。Natsuyasumi ni aetara ii ne.From the letter: It'd be nice if we could meet in summer.
明日晴れたらいいね。Ashita haretara ii ne.It'd be nice if it's sunny tomorrow.

〜てる is 〜ている with the い dropped, extremely common in speech and chat. 〜たことがない is the plain negative of 〜たことがあります. 〜たらいいね expresses a shared wish: if only, wouldn't it be nice. And 〜ことになった, in 始めることになった, says that something has been decided, often by circumstances or other people rather than by the speaker alone; it is a modest way to announce news.

The same message in polite Japanese

To feel the difference, compare a few lines with their polite equivalents, as you might write to a teacher or an older acquaintance. The polite version is longer, uses です and ます, keeps its particles and replaces ね-heavy endings with fuller sentences.

Neither version is better. Casual Japanese to a teacher would sound overfamiliar; polite Japanese to a close friend can sound cold or even hurt. Choosing the right register is part of reading and writing well.

Two message bubbles side by side: a casual note to a friend on the left and a polite note to a teacher on the right, with matching lines linked by arrows.
Same news, two registers: casual for a close friend, polite for a teacher.
JapaneseRomajiMeaning
お元気ですか。Ogenki desu ka.Polite: How are you?
お久しぶりです。Ohisashiburi desu.Polite: It has been a long time.
写真をありがとうございました。Shashin o arigatō gozaimashita.Polite: Thank you for the photos.
来月から新しい仕事を始めることになりました。Raigetsu kara atarashii shigoto o hajimeru koto ni narimashita.Polite: I will be starting a new job next month.
また連絡します。Mata renraku shimasu.Polite: I will be in touch again.
お体に気をつけてください。Okarada ni ki o tsukete kudasai.Polite: Please take care of yourself.

Reading traps in this text

  • マリアが好きだったラーメン屋 is a plain past clause describing the shop: the ramen shop Maria used to like. It is not the ramen shop that liked Maria.
  • 「マリアちゃんは元気?」って聞いてた uses って, the casual form of the quoting particle と. 聞いてた is 聞いていた: he was asking.
  • 私、来月から starts with a topic and a comma instead of は. Casual writing often uses the comma where speech would pause.
  • 楽しみ alone is a complete casual sentence. A noun or な-adjective can end a casual sentence without だ, especially in messages.
  • 行ってみたいな combines 〜てみたい, want to try, with な, a soft ending that sounds like thinking aloud.

Check your understanding

Answer the questions about the letter. The answers follow.

  • What is the weather like where Yui lives?
  • What news does Yui share about herself?
  • Why does Yui want to go to Spain someday?

JapaneseRomajiMeaning

Notice that the answers are in polite form even though the letter is casual. Answering a question about a text is a new situation with its own register, which is exactly how JLPT answer choices are written.

Read it aloud like a voice message

  • Read the first four lines with a rising, friendly tone on 元気? and a soft falling ね.
  • Keep the contractions short: futteru, kiiteta, shiteru, tsuzuketeru; do not stretch them back into teiru.
  • Read 〜んだ as one quick unit, n da, with no pause before it.
  • Read the whole letter at a relaxed speed, as if talking to a friend on the phone.
  • Then read the polite lines from the comparison section and notice how your voice becomes slower and steadier.

Write back to Yui

The best follow-up to reading a letter is answering it. Write Maria's reply in casual Japanese and send it to Mocchi on Unihongo with /correct; ask it to keep the casual tone and point out any line that sounds like a textbook. Because Mocchi remembers the mistakes you make, a later review can check whether you still drop the wrong particles.

Then say your news out loud. In AI Sensei, ask Haru-sensei to play Maria on a call and to switch to casual Japanese, and tell Haru-sensei about your week, your plans and when you might meet. Casual speech is hard to practise with a textbook, so ask him to point out any line that slipped back into です and ます.

Key points

A practical way to improve

Read the letter once as Maria would, for the news. Then read it again and circle every casual feature: 〜てる, 〜んだ, dropped particles, ね and よ. Next, write a reply from Maria in eight to ten casual lines: thank Yui, congratulate her on the new job and answer the question about Japanese study. Ask Mocchi to /correct your reply and to tell you whether any line sounds too stiff or too polite for a close friend. Finally, read Yui's letter aloud in a relaxed voice, as if you were leaving a voice message.

FAQ

Frequently asked questions

Is it rude to write casual Japanese to a friend?

No. With close friends of a similar age, casual Japanese is normal and polite forms can feel distant. Use polite forms with people you have just met, older people you do not know well, teachers and colleagues, unless they invite you to be casual.

What does the ending 〜んだ mean?

〜んだ (from 〜のだ) adds an explanatory or sharing tone. 行ったんだ is like I went, you know, or guess what, I went. The polite version is 〜んです. Overusing it can sound insistent, so learners usually do best using it for news and explanations.

Do Japanese people still write paper letters?

Some do, especially for New Year cards, thank-you notes and formal occasions, but everyday news between friends is mostly sent through messaging apps such as LINE. Formal letters follow different rules, with set openings and seasonal greetings.

Why is there no を in 写真ありがとう?

In casual speech and chat, particles such as を, は and が are often dropped when the meaning is clear. 写真ありがとう means thanks for the photos. In polite writing you would add more: 写真をありがとうございました.
