What you want, apart from the fact that it's politically impossible in Congress and most states and localities, is most certainly not legally "easy peasy." If it was, anti-gun jurisdictions would never include the ubiquitous "grandfather" provisions in their gun control regulations.
If you want Japan-style gun control in the USA, you will need to repeal the 2a (and the analogs in virtually all state constitutions), and then obtain sufficient popular and electoral support to pass such legislative restrictions (to say nothing of actual enforcement and compliance). Since a Democratic Senate couldn't even pass UBC's, despite claiming 90% popular support and the death of 20 children at Sandy Hook, you'll need far more than luck to achieve your goals.
