Raising Bilingual Kids When One Parent Doesn’t Speak the Home Country’s Language

Japan Spouse Visa for Americans: What to Expect When Your Partner Is Japanese

529 or NISA? Saving for Kids Who Might Grow Up in Both Countries

By Dako If you have family in Japan, you’ve heard some version of it. “Put that into a NISA. It’s tax-free now, forever.” The US side says 529, usually with less explanation. Both sides are describing a real thing. Neither…

How Annual Gifting Can Reduce Your Exit Tax Bill

Social Security × Nenkin: How the US-Japan Totalization Agreement Works

Raising Kids Between Two Countries: What a Dual-Base Life Would Mean for School, Friends, and Stability

FBAR & FATCA: The Reporting Rules Mixed-Nationality Couples Forget

By Dako We have a bank account in Japan that earns nothing, owes nothing, and exists to pay for train tickets and dinners when we’re back. It’s in my name because Japanese banks don’t do joint accounts. Money goes in…

How Japan Taxes Your 401(k) and IRA: What Changes the Day You Become a Resident
