In Japan they don't use any computers etc until a much older age in school; interestingly much of that stems from a worry of hindering a student's ability to write kanji.
Having dabbled in kanji, my initial assumption is that such a worry is justified. With English you have 60 or so characters you need to know how to write, many near duplicates (X vs x, U vs u). Kanji is far more numerous and also seems to have a more artistic emphasis.
Yeah, the worry's pretty unambiguously justified; even today, native speakers sometimes just forget how to write words they know. It's just a question of how much it matters.
Hi there! Unfortunately (or fortunately), they DO use computers in schools in Japan now. Albeit not like handing out Chromebooks, but there is computer classes and computer time. In Middle school, I believe there is a small push to use iPads and the like on occasion.
So, there is SOME use, but not like a Chromebook for everyone (Thank heavens!)
