I assume they mean it was made in Japan, by Moki.
I can not help much, as it has no identification marks on? but one possibility is to contact Moki, with a picture, and ask them if they made that knife.
However, I would have expected a standard production knife to have some markings on it. It looks nicely made, but possibly made by a small, unknown maker/company-in a variety of countries really.
We have some Japanese experts, that will hopefully respond soon
