How ChatGPT Enhances Business Email Writing in Japanese

1. Structuring Emails Correctly

Japanese business emails typically follow a specific format, which includes:

1. Greeting (挨拶, aisatsu) – A polite opening.

2. Self-introduction (自己紹介, jikoshōkai) – If necessary.

3. Purpose of the email (用件, yōken) – The main message.

4. Closing statement (結び, musubi) – A polite ending.

5. Signature (署名, shomei) – Your contact details.

ChatGPT can generate a properly structured email, ensuring that you don’t miss any essential elements.

2. Choosing the Right Level of Formality

Japanese has three levels of politeness:

• Casual (ため口, tameguchi) – Used among close colleagues or friends.

• Polite (丁寧語, teineigo) – Suitable for most business interactions.

• Honorific (敬語, keigo) – Required when addressing superiors or clients.

ChatGPT can adjust the formality based on the recipient, ensuring that you use appropriate expressions. For example:

💬 Polite: ご連絡いただきありがとうございます。 (Thank you for reaching out.)💬 Honorific: ご連絡を賜りまして、誠にありがとうございます。 (We sincerely appreciate your contact.)

3. Correcting Grammar and Natural Flow

Even if you’re familiar with Japanese, grammar mistakes or unnatural phrasing can make your email sound awkward. ChatGPT can:

✔ Correct grammar mistakes✔ Suggest better phrasing✔ Ensure a natural, professional tone

For example, if you write:💬 Incorrect: すぐに返事をすることをお願いします。💬 Corrected: お早めにご返信いただけますと幸いです。 (We would appreciate your prompt response.)

4. Translating and Rewriting English Emails in Japanese

If you struggle to write emails from scratch, ChatGPT can translate your English email into proper business Japanese while maintaining the intended tone. Instead of using direct translations, ChatGPT provides contextually appropriate expressions that match Japanese business etiquette.

5. Providing Industry-Specific Phrases

Different industries use specialized vocabulary. ChatGPT can suggest industry-specific terms to ensure your email sounds professional. Whether you're in finance, technology, healthcare, or marketing, ChatGPT can provide relevant expressions.
