Or so I'm guessing, as I don't have any knowledge of the language...to be honest, I just thought the whole clip too funny to not pass it on!

Yes, the voice-over phonemes are particularly unusual

Google Translate gave me this:

The first video you should watch after purchasing! If you look at this, you can easily create without hesitation! I made this video with the aim of making such a video (lol)
(人´∀`)♪ Please watch it over and over again to make sure you know in your head which menu the necessary tasks are hidden in! It will speed up production speed.

Also Band In A Box 30?

Build 924 was from the 2022 release. But I don't know what the '30' related to.

My guess would be the program being some 30 years old overall. The whole speaking part I'm pretty sure is artificial, btw, but can't for the life of me figure out they went with that. Makes the whole thing look like some very strange kids TV show!

P.S. And I have to say, for Google transportation that came out surprisingly intelligible!

The Japanese versions of Band-in-a-Box list differently than by year.

Version 30 is equivalent to Version 2022.

But don't worry - the features are the same!

Thanks for the explanation.
