Good luck with your journey. Brave that you make it public, there will be assholes out their who would like to sturr shit about this topic maybe. It's kinda ridiculous there are laws out there. That you aren't allowed to what you think is best for your children. Just the government trying to control the population from youth till adults that they should be tax paying hard working achievers to their guidelines. You have qualities as an experienced teacher to even homeschool too. Maybe you can setup your own private school business and slip through that way. Isn't Japan filled with these private school organizations? Businesses more or like?
