About us

We're building the future of the phone call.

Mirai Koru is a Japanese company on a simple mission: no customer should ever go unanswered. We combine the latest voice AI with the care and precision of Japanese hospitality.

未来

Mirai (未来) means "the future." Koru is the call. Our name is our promise: the call of the future, available to every business today.

Our story

Great service shouldn't depend on who's free to pick up.

Across Japan, hotels, clinics and local businesses face the same challenge: more customers, many of them from overseas, and fewer people to answer the phone.

Calls go to voicemail after hours. Staff are pulled away from guests and patients in front of them. International callers hang up when no one speaks their language. Every missed call is a missed booking and a disappointed customer.

We started Mirai Koru to fix that. Our AI voice agents answer every call with the warmth and attention to detail that Japanese service is known for, in any language and at any hour, so your team can focus on the people in front of them.

A message from our founder

Japanese hospitality is something the world admires. But with fewer people to answer the phone, delivering that care on every single call has become hard. I started Mirai Koru so technology can help every business give every caller the attention they deserve.
