Don't forget to teach them various European histories & arts, faiths, tales, cultural practices. There is a lot of cultural exchange between Japanese and Europeans, and almost no exchange between different European nations, despite them being so closely related. (Aside from American Kikes blasting media into everyone's faces). There's only so much time for learning about these things and the current education system is very bias. History of ancestors and close nations should be the highest priority, so they can develop a better appreciation & sense of purpose or belonging.
