## What is Keigo Switch?

How would you make an everyday Japanese phrase sound professional at work?

Keigo Switch helps you recall natural business Japanese from casual prompts. Each daily session has 10 prompts and takes about three minutes. Say your answer before revealing it, then save difficult phrases for review.

• 210 original phrases across seven workplace situations, including Meetings and Customer Service
• Clear usage situations and practical notes
• Search casual wording, polite wording, and situations
• Japanese system voice playback
• A review queue for difficult phrases
• On-device learning progress

The first 35 phrases are free. A one-time KeigoSwitch Pro purchase unlocks the other 175 phrases and future Pro expressions. There is no subscription.

Designed for new professionals, job seekers, and anyone who wants more confidence using polite Japanese at work.
