How to Master the Japanese Particle も

Table of Contents

Quick-Start Overview

The Japanese particle も is a multitasker: it adds the sense of “also/too,” strengthens statements to mean “even,” highlights unexpectedly large amounts, and forms the indispensable negative structure “～も…ない” (“not even”). Mastery of も unlocks more natural, native-like fluency. This lesson breaks down each use-case, supplies plenty of model sentences, spotlights tricky exceptions, and finishes with targeted exercises so you can confidently drop も into everyday conversation.

Basic Meaning: “also / too”

When you want to say “A, and B too,” attach も to the element that is “also.” It replaces は, が, or を rather than stacking on top of them.

  • JP: 私わたしは寿司すしが好すきです。刺身さしみも好すきです。
    EN: I like sushi. I also like sashimi.
  • JP: 彼かれも来きます。
    EN: He will come too.
  • JP: 今日きょうは雨あめだし、明日あしたも雨あめらしい。
    EN: It’s raining today, and it looks like it will rain tomorrow too.
  • JP: 私わたしはビールを飲のみます。友達ともだちもビールを飲のみます。
    EN: I drink beer. My friend drinks beer too.
  • JP: 日本語にほんごも英語えいごも話はなせます。
    EN: I can speak both Japanese and English.

Key points:

  • も replaces topic/subject/object markers.
  • If multiple も appear, they emphasize inclusiveness (“both A and B”).

Replacing Other Particles with も

も can substitute other particles like に、で、へ when the meaning “also/even” is added. Unlike は/が/を, these particles stay; も piggybacks with them, yielding にも、でも、へも.

  • JP: 大阪おおさかにも行いきました。
    EN: I also went to Osaka.
  • JP: 図書館としょかんでも勉強べんきょうします。
    EN: I study at the library as well.
  • JP: 来週らいしゅうへも行いけますか。
    EN: Can you go next week too?
  • JP: 一人ひとりでも大丈夫だいじょうぶです。
    EN: It’s fine even by yourself.
  • JP: 二時間にじかんにも及およぶ会議かいぎだった。
    EN: It was a meeting that lasted as long as two hours.

Note:

  • に＋も often signals adding another destination/recipient.
  • で＋も can mean “even with” or “also at.”

Emphatic も: “even” & Large Quantities

Attach も to stress surprise or unexpectedness.

  1. “Even” (positive)
  • JP: 赤あかちゃんでも分わかる。
    EN: Even a baby can understand.
  1. Large numbers: “number + も”
  • JP: 百ひゃく人にんも来きた。
    EN: As many as a hundred people came.
  • JP: 三回さんかいも聞きいたのに覚おぼえられない。
    EN: I heard it three whole times and still can’t remember.
  • JP: 五千円ごせんえんも払はらったの？
    EN: You paid as much as five thousand yen?

Behind the scenes:

  • Think of も as spotlighting the magnitude: “no less than,” “as much as,” “as many as.”

Negative Pattern ～も…ない

Structure: word + も + negative verb/adjective → “not even…,” “no … at all.”

  • JP: 一円いちえんも残のこっていない。
    EN: There isn’t even one yen left.
  • JP: 誰だれも来こなかった。
    EN: No one came.
  • JP: 時間じかんが少すくしもない。
    EN: I don’t have even a little time.
  • JP: 水みずすら／さえ飲のめない。
    EN: I can’t drink even water.
    (Here, すら・さえ replaces も for stronger emphasis; see comparison below.)
  • JP: 彼かれには一度いちども会あったことがない。
    EN: I have never met him even once.

Pattern tips:

  • Noun＋も＋ない
  • Quantity word＋も＋ない
  • Interrogative＋も＋ない (だれも、なにも、どこも)

Rule Exceptions & Edge Cases

  • Double も in the same clause often equals “both… and…”
    JP: 父ちちも母ははも教師きょうしです。
    EN: Both my father and mother are teachers.
  • も after interrogatives drops the question sense in negatives (“だれも来ない”). In affirmatives it means “everyone,” “anywhere,” etc., when paired with でも:
    JP: どこでもいいよ。
    EN: Anywhere is fine.
  • も cannot follow は directly (*はも) because は would already banish itself. Switch は to も or omit は.
  • When stacking particles other than the core trio (は/が/を), keep both: にも、でも, etc.
  • Beware fixed idioms like 何なんとも言いえない (“I can’t really say”). They may defy literal breakdown.

Similar But Don’t Confuse With…

Comparison: も vs は vs さえ／すら

  • Focus:
    は = contrast/topicalize
    も = add/agree/emphasize
    さえ／すら = “even” with stronger surprise, often negative

Minimal pairs:

  1. Addition vs contrast
  • JP: 猫ねこは好すきだが、犬いぬは好すきじゃない。
    EN: I like cats, but I don’t like dogs.
  • JP: 猫ねこも犬いぬも好すきだ。
    EN: I like both cats and dogs.
  1. Light “even” vs heavy “even”
  • JP: 子供こどもでも（＝も）分わかる。
    EN: Even a child can understand. (mild)
  • JP: 子供こどもさえ分わからない。
    EN: Even a child can’t understand. (stronger astonishment)

Exercise Drill

Fill in each blank with the most natural particle: は／が／を／も／に／で／さえ

  5. 春はる____ 花見はなみに行いく人ひと____ 多おおい。
  6. 誰だれ____ 答こたえられなかった。
Answers
  1. 私は…紅茶も
    • First clause sets topic with は; second uses も to mean “also.”
  2. 千円も
    • Emphasizes “not even a thousand yen.”
  3. 雨が…日でも
    • が marks subject “rain falls,” でも = “even on days when it rains.”
  4. 彼が…先生も
    • が shows agent; も = “even the teacher was surprised.”
  5. 春は…人が多い
    • は sets season; が marks subject of “is many.”
  6. 誰も
    • “No one could answer.” Uses も + negative.

Culture Nuggets

  • In casual speech, も often turns into んも after nasal sounds for emphasis: そんなんも知しらん！
  • Comics frequently repeat も three times (ももも!) to show comedic overwhelm.
  • Osaka dialect sometimes doubles も (“～もて”) as in 食たべてもて meaning “ended up eating (too).”
  • Japanese slogans leverage 数字＋も for exaggeration: 一日いちにちに百回ひゃっかいも笑わらおう! (“Let’s laugh as many as 100 times a day!”)
