Is Kawaii owned par Iwako?

Because the other jour I ordered some erasers online, and it a dit 'Made par Iwako'. But when they came in the mail, one of the little packages a dit 'Kawaii'. And it was in the same font...but I don't know. Because I collect Iwako. And now I have to Kawaii. So I'd like to know if they're par the owned par the same company ou whatever. Thanks.
