Trad or Roth IRA

Sorry if this has been asked before. I currently work in the US and my wife is Japanese. She wants to move back to Japan in the next 5-10 years as a family. I have been maxing out my roth every single year and heard that Roth IRA is not viewed as a retirement account in Japan so it will be taxed when I withdraw money. Does it make sense to contribute to traditional IRA so I’ll only be taxed once when I withdraw during retirement? Thank you.
