@Laner how do you find the school system there so far
We are back in Vancouver now. Overall it was good, with Japanese elementary school being extremely good by comparison.
There is a good variation between work/play/sports. My son enjoyed the focus on art (mostly drawing) and gym (which is everyday, sometimes twice, and pretty stern on athleticism). Math is pretty advanced comparatively, so he struggled there. Same with geography, which Japanese kids know a lot about. But it is very Japanese centric, so my son did struggle with this but nothing an afternoon of homework couldn't solve.
The kids also all do juku (after school tutoring) to some degree. In elementary and part of junior high, it's more of a conditioning exercise. It becomes very important in the latter part of junior high as competition for high school placements becomes
almost an obsession. It then goes to new heights during high school where university admission
is an obsession.
The positives are that the system in Japan fosters, encourages and makes pathways for the best and brightest. Vancouver has gone the opposite, completely shutting down the advance education system two years ago. There is also a high respect for athleticism - sports days should be visited by any visiting family to Japan. Kids learn music at the same time they are developing their kanji (Chinese), which makes so much sense. There is a lot of patriotism in the education, which is awesome if you are Japanese. They are definitely not taught to hate their culture. Much the opposite, which many westerners actually find to be problem (lol).
And of course not once even seeing or hearing mention of LGBT or BLM or any of the other pet causes that seem to distract us so efficiently here in the west. The kids are still comfortable and happy to spend time in mixed groups (which actually threw my son off to some degree). All the girls dressed modestly and there were no whores-in-training to be seen by the casual observer - which I think has a huge effect on boy/girl groups in the west. 10yo boys want nothing to do with 10yo girls who are learning Dua Lipa dance moves while flashing their underwear, and for good reason. Japan, like much of conservative Europe, still uses the local grandmas to police the kids.
If we end up back in Japan for a spell, we would most likely have to put him into an international school. It would just be too much to be able to catch up to the Japanese kids. I am sure it would be possible for the right kid, but realistically it would be pretty rough on the boy. But if you can start your kids off in kindergarten, they would benefit a great deal from some years of Japanese education.
