Key Points

  • AI lets you write client-ready English, but a raw translation as-is is risky for tone and naturalness
  • Ask by scene (short reply, proposal, presentation script) with recipient, relationship, and industry context
  • 2-stage workflow: translation-specialized tool for rough → AI for business tone → resident tool to check
  • Avoid 100%-AI/literal/long/passive; a human always confirms names, amounts, dates; check terms for confidential text

Even If You're Weak at English, You Can Write Business English with AI

Even without confidence in English, with AI you can write English you can send to a client. But "sending the translation as is" is risky. Translation carries meaning but doesn't guarantee whether it's natural as a business document or whether the tone fits your relationship with the recipient. Here's how to write and fix, organized by scene.

How to Ask, by Scene

1. Short Email Reply

Write the gist in Japanese and add the recipient's position and relationship, then ask for a translation.

Make the following into a polite business English email.
Recipient: a US client CEO. Not a first meeting, but keep formality.

2. Proposal/Plan

Translate the Japanese draft → adjust per section:
- First translate the whole structure
- Specify each section as "executive-summary style," "data-focused"
- Confirm jargon translation separately

3. Presentation Script

Spoken English differs from written English. Ask for the oral version separately.

Into English speakable in a 5-minute oral presentation.
Output speaker notes and slide text separately.
