Business Japanese for IT Companies

Meetings, emails, Slack messages, and code review — the Japanese your tech workplace expects.

Cultural Tips

  • "Otsukaresama desu" is not just a greeting — it's how you start every email, Slack message, and even phone call to colleagues. Skipping it feels abrupt and slightly rude.
  • In meetings, don't interrupt. Wait for a natural pause or for the speaker to finish completely. Even if you disagree, frame it as "I see your point, but perhaps we could also consider..."
  • Japanese email closings matter. "Yoroshiku onegai itashimasu" is the standard — it roughly means "I'm counting on you" and is expected in every business email.

FAQ

How formal should I be in Slack vs email?

Slack is semi-casual — you can drop some keigo but keep it polite. Email is fully formal. When in doubt, be more polite than you think necessary. SayLy can help you adjust the tone of your messages in real time.

Do I need keigo for code review comments?

Typically yes, especially when reviewing a senior's code. Use softer phrasing like "~dekisou desu" (seems like it could be) instead of direct commands. For peers, you can be more casual but still polite.

With SayLy, just type in your language and send natural Japanese. No memorization needed.
