Need help getting a Japanese credit card – rejected by Rakuten and Life DP

I'm trying to get a Japanese credit card for websites that require Japanese-issued cards (3D authentication failures with my US cards). I have solid US credit (800 score, multiple cards) and physical retail stores work fine, but some sites and services like iOS app store Japan specifically need a Japan-issued card.

As for me:

  • Have Japanese dependent visa (3 years)
  • Not working and not planning to work in the near future (FIRE'd)
  • Got rejected by both Rakuten and Life DP credit cards (Cash secured card)
  • Applied to both cards using my Japanese bank account with 300 man yen

I'd also like to build Japanese credit for potential future needs (maybe a business loan). Given my situation, what's the best way to get a Japanese credit card & build credit?
