Well, it is indeed pretty similar even down to the "art style", at least it uses the same idea. But I'd just call it inspiration, the style itself is different and it's hard to be original nowadays anyway.
They also called out Kana Nishino's new best albums plagiarizing a remix album of Kylie Minogue and that's the same case. Not a big deal imo, especially if the artwork is simple like in both cases. People can have the same ideas.
Intentionally doing the same is plagiarism.
