Restrictions on the send of messages in the Biz Message API

We are gearing up to use the BizMessageAPI in the future.
We would like to ask you about the nighttime transmission limits.
It was mentioned in the document that there is a transmission restriction between 20:00~8:00.

If our destination is a Japanese user and not a Korean user, is this restricted?

The message composing screen stated the following.

한국 사용자는 20:00부터 08:00까지는 메시지 수신이 불가하여 익일 오전 08:00 이후에 메시지를 받게 됩니다.
해외 사용자에게는 시간 제한 없이 보내지니 참고해 주세요.

If I’m using BizMessageAPI to send to Japanese users, can I also send between 20:00~8:00?

We need your help.

Thank you.

Hello!
When the user has Japanese mobile number, you may send messages between 20:00~8:00.
But I’m not sure whether it is possible because it depends on the country’s policy.
In Korea, sending marketing messages in the night is prohibited by law.

Thank you for your reply.

There is no such law in Japan.
So, we can send it to Japanese users without any time limit.

Am I correct in assuming that the BizMessageAPI has no systemic transmission limits?

Yes, there is no limit about this issue. Following text you’ve seen means that.

“해외 사용자에게는 시간 제한 없이 보내지니 참고해 주세요.”

Thanks!
