Gift Tax and Transferring Funds for Buying Property

Hi everyone, my wife and I are feeling pretty uncertain about how best to proceed with a possible property purchase in Japan (we live around Fukuoka, currently renting for last 3 years), and I’d appreciate any insight from people who’ve dealt with similar situations.

We’re a U.S./Japan household currently living in Japan. I'm a U.S. citizens and my wife is Japanese, and I’m here on a 3-year spouse visa (maybe going for PR next year). I recently started working at a local Japanese business after freelancing last few years, and my confirmed annual salary is about ¥4.29 million. My wife is not currently working (recently diagnoses have made keeping a job difficult), and we have an infant daughter.
Our goal is fairly modest: we’re hoping to lower our monthly housing costs so I can more sustainably support my family on my current income. We’re not aiming for a long-term “dream house” right now. Instead, we’re considering buying a relatively affordable used manshon as a practical step, even if only temporarily. As an example, we’ve seen places around ¥13.5 million.

My parents in the U.S. are willing to help us financially as an early inheritance, ideally by covering a cheaper place outright to avoid loan complications given my current resident status. However, we’re struggling to understand the cleanest and safest way to structure that help, while staying compliant with both Japanese and U.S. tax rules.

Specifically, we’re confused about:
– How Japan’s gift tax rules would apply (¥1.1M annual exemption, housing gift exemption of ¥5M / ¥10M, etc.). (And do we need evidence of purchasing the property with that money, my relationship with my parents, being foreigners, etc.)

  • Whether the housing gift tax exemption could realistically be used in a case like this. If my goal is to pay off the entire property, then this wouldn't be enough at the highest exemption without incurring high taxes I can't pay, right? Is it even worth it in our case, for example, to just use the exemption but pay the taxes on the remaining amount?

  • Whether early inheritance (相続時精算課税) is something people actually use here. I saw it may have a lot of loops, but this is technically meant to be a partially early inheritance to help my family before my parents pass away someday.

  • Whether it materially changes anything if funds come from my own overseas accounts versus direct family assistance.

  • What the realistic risks are if this is structured poorly. (Unforeseen financial risks for an expat are already scary enough as it is.)

We’re not trying to do anything aggressive or questionable, just trying to understand what paths people normally take in situations like this and what tends to be recommended or avoided.

It’s also late in the year, so timing may matter if certain options depend on the tax year to my understanding.

Any experiences, pointers, or corrections to misunderstandings would be very appreciated. And please excuse my ignorance on the matter~
