と言いえば and そういえば: how to say "speaking of" in Japanese

〜と言いえば (to ieba) is "speaking of 〜": you pick up a word someone just said and use it as a bridge to your own topic. そういえば (sou ieba) is "oh, that reminds me": a softer turn to something new. Both are the tools Japanese uses to move a conversation along without an abrupt jump.

They are small phrases, but they do a lot of social work. A conversation in Japanese rarely changes topic cold; one of these usually sits at the hinge.

The basics

What does と言いえば mean?

Noun + と言いえば is "speaking of [noun]" or "when it comes to [noun]." It picks up a word that is already in the air and uses it as the topic for what you say next.

A: 来週らいしゅう、京都きょうとに行いくんだ。 B: 京都きょうとと言いえば、紅葉こうようがきれいな時期じきだね。 — A: I'm going to Kyoto next week. B: Speaking of Kyoto, it's the season for autumn leaves. (picking up the word) 夏なつと言いえば、花火はなびだよね。 — When you think of summer, it's fireworks, right? (the classic association) 仕事しごとの相談そうだんと言いえば、面白おもしろいサービスがあるよ。 — Speaking of asking for advice about work, there's an interesting service. (bridge to a new point)

It is written と言いえば or といえば; both are common. The ば is the conditional — literally "if you say [noun]…" — covered in たら, ば, と and なら.

What is the "X と言いえば Y" pattern?

A very common use is naming the thing everyone associates with X. 日本にほんと言いえば寿司すし — "when you say Japan, (people think of) sushi." It is how Japanese talks about symbols, specialities and clichés.

Pattern Meaning
夏なつと言いえば、花火はなび Summer means fireworks
大阪おおさかと言いえば、たこ焼やき Osaka is famous for takoyaki
秋葉原あきはばらと言いえば、アニメ Akihabara is all about anime
冬ふゆと言いえば、こたつ Winter means the kotatsu

This is also a common quiz-show and advertising format: 〜と言いえば? ("What comes to mind when I say ~?").

What does そういえば mean?

そういえば is "that reminds me," "come to think of it" or "by the way." It does not need a word from the other person — it signals that you have just remembered something, which may or may not be connected.

そういえば、昨日きのう田中たなかさんに会あったよ。 — Oh, that reminds me, I ran into Tanaka yesterday. (a new topic) そういえば、最近さいきんあの店みせ行いってないね。 — Come to think of it, we haven't been to that place lately. (a sudden thought) そういえば、宿題しゅくだいあったっけ? — Wait, did we have homework? (remembering something)

そう ("like that") + 言いえば ("if one says") — "now that it's been said…" In writing you will see both そういえば and そう言いえば.

Beyond the basics

What is と言いったら?

と言いったら is a near-synonym of と言いえば, but it often adds emotion: "talk about…!" It is used when the thing is remarkable, good or bad.

あの店みせのラーメンと言いったら、最高さいこうだよ。 — Talk about that shop's ramen — it's the best. (enthusiasm) 昨日きのうの暑あつさと言いったら…。 — The heat yesterday, honestly… (trailing off in exasperation)

A sentence can even stop after と言いったら, and the listener fills in "was unbelievable."

What about といえば in a formal setting?

In meetings or presentations, the smoother version is 〜について言いえば ("regarding ~") or 〜に関かんしては ("as for ~"). と言いえば is fine in business conversation, but a formal change of topic usually uses ところで ("by the way") or さて ("now then").

ところで、来月らいげつの予定よていですが… — By the way, about next month's schedule… (polite topic change)

ところで is a clean switch; そういえば suggests you just remembered. At work, ところで is safer.

What does どちらかと言いえば mean?

どちらかと言いえば is "if anything" or "if I had to choose" — a soft way to state a preference without committing hard. It is the same と言いえば, attached to どちらか ("one of the two").

どちらかと言いえば、夏なつより冬ふゆが好すき。 — If anything, I prefer winter to summer. (mild preference) どちらかと言いえば、静しずかな店みせがいいです。 — If I had to choose, a quiet place would be good. (polite, soft)

It is extremely common in answers to "which do you prefer?", because a flat 冬ふゆが好すき can sound too definite. Japanese conversation tends to leave that bit of room.

How does it sound in anime?

そういえば is one of the most common lines in dialogue, because characters constantly "just remember" plot points. In a mystery, そういえば… is often the line right before the key clue. と言いえば shows up when characters explain things to a newcomer — 秋葉原あきはばらと言いえば、やっぱりメイドカフェ! — which is also how anime sneak in cultural explanations.

For what to do when someone says something you didn't catch before changing the subject, how to ask someone to repeat covers the phrases.

Common mistakes

  • Using そういえば with a noun in front. 京都きょうとそういえば is wrong. With a noun, use 京都きょうとと言いえば.
  • Using と言いえば without a link. と言いえば needs a word already in the conversation. For a cold topic change, use そういえば or ところで.
  • Using そういえば to formally change topics at work. It sounds like you just remembered. ところで is cleaner.
  • Writing とゆえば. The spoken sound is "to yu-eba," but the spelling is 言いえば / いえば.
  • Forgetting the association meaning. 夏なつと言いえば花火はなび is not "if you say summer" — it is "summer means fireworks."
  • Overusing と言いったら. It carries emotion. For neutral links, と言いえば is enough.

Practice

Answers are hidden — build yours first, then open. Questions 1 and 2 are a pair: picking up a word versus a new thought.

1. A friend mentions ramen. Say "Speaking of ramen, there's a new shop near the station."

Show answer

ラーメンと言いえば、駅えきの近ちかくに新あたらしい店みせができたよ — you pick up the friend's word, so と言いえば.

2. Nothing to do with ramen, you suddenly remember: "Oh, that reminds me — the meeting moved to Friday."

Show answer

そういえば、会議かいぎが金曜日きんようびになったよ — a sudden memory with no link: そういえば.

3. Say "When you think of winter, it's the kotatsu."

Show answer

冬ふゆと言いえば、こたつ — the association pattern.

4. Say "Speaking of Akihabara, have you been to a maid café?"

Show answer

秋葉原あきはばらと言いえば、メイドカフェに行いったことある? — と言いえば bridges to your question.

5. In a meeting, change the topic politely to next month's plan.

Show answer

ところで、来月らいげつの予定よていですが… — ところで is the clean, polite switch.

6. Say, with enthusiasm, "Talk about that café's cake — it's amazing."

Show answer

あのカフェのケーキと言いったら、すごいよ — と言いったら adds the emotion.

7. Fix: 旅行りょこうそういえば、パスポート持もってる?

Show answer

旅行りょこうと言いえば、パスポート持もってる? — with a noun, と言いえば.

8. Come to think of it, you haven't seen a friend lately. Say it casually.

Show answer

そういえば、最近さいきん会あってないね — "come to think of it" is そういえば.

9. A quiz host asks: "What comes to mind when I say Osaka?"

Show answer

大阪おおさかと言いえば? — the quiz format ends with と言いえば and a rising tone.

FAQ

Is と言いえば the same as については? Not quite. については is "about," neutral and formal. と言いえば links to something just mentioned or calls up an association.

Is そういえば rude? No. It is friendly and very common. It only sounds out of place when a formal switch is needed.

Can I say あ、そういえば? Yes, and it is very natural. The あ makes the "I just remembered" feeling stronger.

What does と言いっても mean? "Even though I say…" — a correction: 旅行りょこうと言いっても、一泊いっぱくだけ, "It's a trip, but only one night." Different job.

Is といえば written in kanji? Both 言いえば and いえば are common. Newspapers often use いえば in this function.

Can と言いえば come after a verb? Yes, with a nominalized phrase or directly: 勉強べんきょうと言いえば or 勉強べんきょうすると言いえば. The noun version is far more common.

I'm Yuuki, a Japanese teacher based in Tokyo. I've taught on italki as a Top 1% teacher and watched over 1,500 anime. と言いえば is one I use myself in lessons to change the subject — a student mentions a topic, and 〜と言いえば is how I bridge to the next point. It is also one of the easiest phrases to copy, because it starts from a word that is already on the table.
