Any brokers that accept non-Japanese residents?

I really want to buy JP90C000MTN2. Due to PRIIPS regulations, European brokers can only offer Europeans UCITS funds with a valid KID. This means that I cannot just buy Japanese-domiciled nor US-domiciled ones. However, for US-domiciled ETF there are a number of brokers, like Tastytrade, that allow non-US residents to open an account and buy US ETFs. This is well-documented, legal and I tried it. The question is now: are there any brokers that also allow non-Japanese residents to buy ETFs on their exchange?

I know I can become a qualified trader or do stuff with options on IBKR, but I'd rather not if there's an easier solution.

Perhaps unrelated: does anyone know if JP90C000MTN2 borrows its leverage from the Bank of Japan with low interest? If you can provide a good backtest download I can figure it out myself too.
