Japanese Business Phrases: What to Learn First, by Use Case

Table of contents

Who this is for

• Foreign professionals in their first weeks at a Japanese company who haven’t yet figured out what to prioritize
• JLPT N3–N2 learners who can read the phrases but don’t know which ones come up daily
• Global HR and team leads looking for the one page to hand a new hire on day one

If you already know your weak spot — email, meetings, apologies — skip straight to that row in the use-case map.

Which of these is your problem right now?

Business Japanese is too broad to learn all at once. Pick the line that sounds like you and jump:

• “I freeze on greetings and small replies” → start with the starter 20 below, then the use-case map
• “I can’t write the email” → Japanese email phrases and business email templates
• “I can’t speak up in meetings” → Japanese meeting phrases
• “I don’t know how to apologize” → how to say sorry in Japanese politely
• “I stall on self-introductions” → Japanese self-introduction templates
• “I want something to save and print” → the Japanese business phrases PDF
• “I want to understand the keigo behind it” → the keigo guide
• “I just need to look up a verb form” → the keigo cheat sheet

Everything below is the shared foundation: the politeness model, the 20 phrases worth memorizing first, and a one-glance map of every scenario.

A/B/C politeness in 30 seconds

At Real-World Japanese, we treat keigo as three rephrasings of the same intent, so you never have to derive a form from grammar under pressure:

When in doubt, pick B. It’s the safe default for most workplace situations — A with a client is a non-starter, and C with a peer creates odd distance.

One more axis: uchi-soto (内・外, “inside-outside”). Anyone inside your company is uchi; anyone outside is soto. Speaking to soto, you lower your own side — even your boss. That’s the whole reason the same sentence has multiple forms. For the full breakdown, read the A/B/C framework in the keigo guide.

The starter 20: learn these first

Most phrase lists are alphabetical or exhaustive. This one is ordered by how often you’ll hit each phrase in your first week. Learn these and you can hold the floor in most day-one situations. (Frequency is our working estimate; we’re validating it with field data — see the note at the end.)

Need the verb conjugations behind these (iku → ukagau, iu → ossharu)? That’s the keigo cheat sheet. Want the full ready-to-paste sentences? That’s the phrase PDF.

Use-case map: find your situation

Each row gives you one or two anchor phrases to recognize, then points to the deep-dive. This is the map — the linked articles are the territory.

The phrases no phrasebook lists: in-house jargon

Phrasebooks teach keigo. They skip the office jargon and wasei-eigo (和製英語, Japanese-made English) that fly around on your first day — words nobody warns you about because natives assume them. Recognize these eight and you’ll stop nodding blankly in meetings:

• hōrensō (報連相) — report, contact, consult: the expected rhythm of keeping your team in the loop
• nemawashi (根回し) — quietly lining up agreement before a meeting, so the meeting only ratifies it
• tatakidai (たたき台) — a rough first draft meant to be torn apart and improved
• risuke (リスケ) — “reschedule,” clipped; you’ll hear it for any moved meeting
• apo (アポ) — “appointment,” clipped
• buresuto (ブレスト) — “brainstorm”
• konsensasu (コンセンサス) — “consensus,” often paired with nemawashi
• purasu-arufa (プラスアルファ) — “plus alpha,” meaning a little something extra

You don’t memorize these — you recognize them in context. Flag the ones you hear most and look them up the same day.

The politeness mistakes to dodge first

Two errors cost beginners the most credibility, so internalize these now:

• ryōkai shimashita to a client or boss. It means “understood,” but it’s peer-level. Use shōchi shimashita or kashikomarimashita upward and outward.
• gokurōsama to a superior. It thanks someone for their effort — but down the hierarchy. To a boss, it’s otsukaresama desu.

Those are the two that draw a quiet correction. For the full set — sasete-itadaku overuse, double keigo, and more — read the keigo mistakes guide and the broader common Japanese business mistakes.

Your next step

Pick one move, not ten:

1. Memorize the starter 20 until they come out without thinking.
2. Choose the one use case biting you most this week and read its deep-dive from the map.
3. Keep a reference at your desk — the phrase PDF prints cleanly with Cmd + P.

Frequently asked questions

What are the most useful Japanese business phrases?

The highest-frequency ones are otsukaresama desu (a catch-all greeting and acknowledgement), osewa ni natte orimasu (a standard email and phone opener with clients), yoroshiku onegai shimasu (thanks-in-advance and a closer), and shōchi shimashita (“understood,” to a superior or client). Learn those four first, then work through the rest of the starter 20.

Where should I start with business Japanese?

Start with the starter 20, which covers most of what you’ll hit in week one. Once those are automatic, jump to whichever single use case is biting you most — email, meetings, apologies, or self-introductions — using the use-case map. Learn by the situation in front of you, not alphabetically.

What does otsukaresama desu mean?

Literally it’s roughly “you must be tired,” but it functions as an all-purpose workplace greeting, a thank-you for someone’s effort, and a sign-off. You say it passing a colleague, at the end of a meeting, and when leaving the office. It’s the single most-used phrase in a Japanese workplace.

How do you say “understood” politely in Japanese?

Use shōchi shimashita or kashikomarimashita with superiors and clients. Ryōkai shimashita (“got it”) is fine with peers but reads as too casual to a boss or client. The acknowledgement ladder runs from wakarimashita up to kashikomarimashita as the most deferential.

Do I need to learn keigo to use these phrases?

No. Most starter phrases are fixed set expressions you can use as-is. Learn the phrases now and pick up the underlying system in parallel — the keigo guide explains the A/B/C politeness levels that tell you which version of a phrase fits which listener.

Is there a printable list of Japanese business phrases?

Yes — the Japanese business phrases PDF is the dense, saveable scenario library, and Cmd + P (Mac) or Ctrl + P (Windows) prints it cleanly. This page is the lighter starting map: use it to decide what you need, then go there for the full tables.
