According to the above two articles, and several more on Google, your portfolio is protected up to 1千万 if your broker goes bankrupt. Would that mean it's wiser to not keep all our investments in a single brokerage? Say maybe split them between SBI and Rakuten?

I don't have the link anymore but there was another article that mentioned that when a brokerage goes broke, the funds are transfered into a holding company and you can continue trading as usual. Worst comes to worst, you are compensated the cash value of yourt portfolio at time of bankruptcy. These articles are all rather conflicting and I'm not sure what to make of it. For all I know, they're all talking about separate things.

Most brokers should have your assets held separately to the company finances. So in theory they are perfectly safe, although you may not have access to them for a while. Having said that, it can't hurt to spread out over several brokers...

I have accounts with Rakuten and Monex, and my wife has Rakuten and SBI.

Client assets are segregated so theoretically even if a brokerage goes bankrupt you at worst suffer only a delay in getting your funds returned to you. 10 million yen insurance is a small upper limit and when I've asked my Japanese brokerages they stated that they had additional insurance coverage which was much higher (but that the insurance wasn't necessary). I actually worry more about some obscure paperwork rule coming in ("I can't read your gaijin card because the numbers are worn down," "Your signature looks different than before," "The katakana for your name doesn't match what I think it should be," have all been used on me in the past) that meant I wouldn't be able to access funds quickly if I needed and for that reason I spread my investments over multiple brokerages.
