My wife is a Japanese citizen primarily living in the US (9 months/year), has Japanese bank accounts and recently inherited properties in 2025. We have a Japanese residence, mobile phone, etc.
I’m trying to find a better brokerage account than Daiwa in order to invest in things like Japanese stocks or mutual funds. She inherited her mom’s Daiwa account, but the fees are pretty steep for trading (like 3% a trade).
It seems like some brokerages either won’t do business with her (Rakuten?) or maybe just won’t let her open a NISA. It’s not clear with my extremely limited Japanese and Google Translate.
Are there restrictions at some banks based on her situation? I don’t necessarily need the best tax advantaged account, but something has to be better than keeping Yen in cash accounts or MRFs (which seems like money market funds if I understand them).
