That has to be a joke. This has no hint of tentacles or sexualization that I see. It's a couple of youngish* people sharing or (long shot, if you take the greedy view) tugging over the box of sweets.
*The age is hard to tell, it's like trying to divine Buggs Bunny's age from his cartoons. But the age is irrelevant as it's two people with a box of sweets.
Maybe if it was teenage girls all the way around. If a 25+ year old male had that laying around, I guarantee you all the women I know would non-judgmentally classify him as 'probably hentai'.
Yeah I think it's really borderline, besides the product is candy - not girls so why make girls the main / standout part of the very publicly visible packaging. It just looks... Dodgy!
Sort of... It follows Japanese advertising characteristics and they are selling Japanese candy. So.... But, yes, I think the people depicted are too prominent and the candy should be more conspicuous. The packaging might benefit by giving the candy more prominence?
