I also checked that all the "home-based Hokkaido milk cakes" sold in China are basically produced by a domestic foundry entrusted by a company called "Hong Kong Liangyou Food International Co., Ltd.".
Trademark inquiry also shows that the trademark "Jiarun Mu Yi CuO" is indeed owned by this "Hong Kong Liangyou Food International Co., Ltd.". The products that this company can find in official website are basically "fake" Japanese goods with the words "Hokkaido" written on the package.
But because their company didn't explicitly say that their products were made in Japan, it wasn't fraudulent for consumers. And judging from their company official website, this company has no overseas business. Most of their products are also commissioned by domestic foundries.
So we have reason to suspect that this company is targeting domestic consumers. Taking advantage of the good development of Haitao business in the past two years, we can only remind everyone to keep their eyes open when spending in the future.
