Business Japanese Guide: Key Phrases, Etiquette & Test Prep

Business Japanese is essential for professional success in Japan, requiring mastery of keigo (honorific language), appropriate phrases, and workplace etiquette that differs significantly from casual Japanese conversation.

Working in a Japanese company means entering a world where language does more than just communicate—it shows respect, builds relationships, and establishes your professional credibility. Whether you’re preparing for a job interview in Tokyo, collaborating with Japanese clients, or planning to take a business Japanese proficiency test, understanding how to speak and behave in professional settings is crucial.

Understanding What Business Japanese Is

Business Japanese is the formal version of the Japanese language used in professional environments. It represents more than just vocabulary changes—it involves a complete shift in how you express yourself, show respect to others, and position yourself within workplace relationships.

What Makes Business Japanese Different from Standard Japanese

Business Japanese operates on fundamentally different rules compared to conversational Japanese. The most visible difference lies in the language structure itself—special verb forms, specific vocabulary, and formal expressions replace their everyday equivalents.

The key structural differences include verb endings, vocabulary choices, communication style, and non-verbal elements. While casual Japanese uses plain forms (like “行く” – iku for “go”), business Japanese requires polite forms at minimum (“行きます” – ikimasu) and often honorific forms (“いらっしゃる” – irassharu when speaking about someone else’s actions). Standard words get replaced with business equivalents: “会社” (kaisha) becomes “御社” (onsha) when referring to someone else’s company, while your own company is “弊社” (heisha).

Japanese business culture values indirect communication over direct statements. Rather than saying “no” directly, professionals use phrases that soften refusals or suggest reconsideration, helping maintain harmony (wa) in professional relationships. Business Japanese also includes physical etiquette—how you bow, exchange business cards (meishi), and even how you sit in meetings communicate respect just as much as your words.

The cultural context matters enormously. Japan’s collectivist society emphasizes group identity, creating the concept of “uchi” (inside/in-group) versus “soto” (outside/out-group). You’ll speak differently depending on whether someone belongs to your company group or represents an external organization.

Importance of Keigo (Honorific Language) in Professional Settings

Keigo forms the foundation of business Japanese communication. This system allows speakers to show respect, demonstrate humility, and navigate Japan’s hierarchical social structure. Mastering keigo is not optional for professional success—it’s expected behavior that signals your cultural understanding and professionalism.

The keigo system consists of three main categories:

Japanese business culture reflects deeper values of respect for hierarchy and social harmony. Using proper keigo shows that you understand your position relative to others and respect the established social order. Customer service roles require consistent keigo use, business emails demand careful construction, and phone conversations follow specific patterns.

Common Mistakes Learners Make When Using Business Japanese

Understanding typical errors helps you avoid them. Common mistakes include:

Mixing keigo levels: Using sonkeigo when kenjōgo is appropriate, or vice versa. When talking to a client about your boss’s actions, you must use humble language even though your boss has higher status, because to the client, your entire company represents your in-group.

Overusing or underusing keigo: Some learners apply maximum politeness to every situation, creating awkward, overly formal interactions even with colleagues of similar rank. Others underestimate when formality is required, damaging professional relationships through insufficient respect. The key is matching your language level to the specific relationship and situation.

Using inappropriate vocabulary:

• ❌ “すごい” (sugoi – amazing) → ✓ “素晴らしい” (subarashii – excellent)
• ❌ “ちょっと待って” (chotto matte – wait) → ✓ “少々お待ちください” (shoushou omachi kudasai – please wait a moment)

Essential Business Japanese Phrases and Vocabulary

Mastering key phrases and vocabulary accelerates your ability to function in Japanese business environments. These expressions appear daily in Japanese workplaces and form the foundation of professional communication.

Daily Workplace Greetings and Expressions

Mastering daily greetings and expressions creates a positive impression and helps you integrate smoothly into Japanese workplace culture. These phrases form the backbone of professional interactions and are used multiple times throughout the workday.

Essential daily phrases:

• Morning arrival: “おはようございます” (ohayou gozaimasu – good morning)
• Leaving temporarily: “行ってきます” (ittekimasu – I’ll be back)
• Response: “行ってらっしゃい” (itterasshai – see you soon)
• Returning: “ただいま戻りました” (tadaima modorimashita – I’m back)
• Leaving for the day: “お先に失礼します” (osaki ni shitsurei shimasu – excuse me for leaving first)
• End of day gratitude: “お疲れ様でした” (otsukaresama deshita – thank you for your hard work)

Most versatile phrase: “お疲れ様です” (otsukaresama desu) – use when greeting colleagues during the day, ending meetings, or acknowledging someone’s effort.

External communications: “お世話になっております” (osewa ni natte orimasu – thank you for your continued support) – start phone calls and emails with external contacts.

Keigo in Action: Sonkeigo, Kenjōgo, and Teineigo Examples

Understanding how the three keigo forms transform common verbs helps you apply them correctly in conversation. The following table shows side-by-side comparisons of the most frequently used verbs in business settings.

Learning keigo becomes easier with concrete examples:

These transformations require memorization because they often don’t follow predictable patterns.

Understanding Keigo Transformation Patterns:

While keigo transformations can seem irregular, there are patterns to help you learn them systematically:

Sonkeigo (Respectful) Patterns:

1. 【お】-stem + になる pattern: For many Group 2 verbs, add 【お】 prefix to the verb stem plus 「になる」 (ni naru). Example: 読む (yomu – to read) → お読みになる (oyomi ni naru)
2. Special honorific verbs: Common verbs have unique sonkeigo forms that must be memorized. These include なさる (nasaru) for する (suru/do), いらっしゃる (irassharu) for 行く (iku/go), and おっしゃる (ossharu) for 言う (iu/say)

Kenjōgo (Humble) Patterns:

1. 【お】-stem + する pattern: For actions directed toward a superior, add 【お】 prefix to the verb stem plus 「する」 (suru). Example: 電話する (denwa suru/call) → お電話する (odenwa suru)
2. Special humble verbs: Common verbs have unique kenjōgo forms. These include いたす (itasu) for する (suru/do), 参る (mairu) or うかがう (ukagau) for 行く (iku/go), and 申す (mousu) for 言う (iu/say)

Understanding なさる (nasaru):

The verb なさる (nasaru) is particularly confusing because it conjugates irregularly. Unlike regular u-verbs, なさる conjugates with special forms:

• Present/future: なさいます (nasaimasu) – NOT なさります
• Past: なさいました (nasaimashita)
• Te-form: なさって (nasatte)- uses 「っ」 instead of 「り」
• Negative: なさらない (nasaranai) or なさいません (nasaimasen)

Similarly, いらっしゃる (irassharu), おっしゃる (ossharu), and くださる (kudasaru) follow this same special conjugation pattern, using 「-います」 (-imasu) instead of the expected 「-ります」 (-rimasu) form.

Phone Etiquette

Professional communication in Japanese follows specific protocols that differ significantly from Western business practices. Mastering these conventions demonstrates your understanding of Japanese business culture and helps establish credibility with colleagues and clients.

Essential Phone Phrases:

Phone Etiquette Guidelines:

• Asking for caller’s name: “失礼ですが、お名前をお伺いしてもよろしいでしょうか” (shitsurei desu ga, onamae wo oukagai shitemo yoroshii deshou ka)[2] 

Formal Meeting Language and Presentation Skills

Meetings and presentations require careful attention to keigo levels and specific phrases that convey professionalism and respect. Using the appropriate language in these settings demonstrates your competence and cultural awareness.

In meetings:

• Use sonkeigo for clients/superiors’ actions
• Use kenjōgo for your own actions
• Asking for opinions: “この件について、ご意見はございますか” (kono ken ni tsuite, goiken wa gozaimasu ka)
• Making suggestions: “〜てはいかがでしょうか” (~te wa ikaga deshou ka – how about~)

For presentations:

• Opening: “本日はお時間をいただきありがとうございます” (honjitsu wa ojikan wo itadaki arigatou gozaimasu)
• Introducing topics: “それでは、〜についてご説明させていただきます” (soredewa, ~ni tsuite gosetsumei sasete itadakimasu)[3]
