As a foreigner in Japan, can I ask my parent to give me less in an inheritance to avoid inheritance tax?

I am the only foreigner and tax resident in my family living in Japan.

Therefore, based on my understanding, the 30 + 6 million yen per statutory heir exemption would be applied to my portion, not the entire value of my parent’s estate.

I’ll give the example of

-1 parent

-1 spouse of parent

-3 children

If my parent’s estate is worth 500 million yen, I could stand to inherit 83 million yen. (250 to the spouse, and 83 to each child).

However, as 83 million yen is above the 30 + 6 million yen per statutory heir exemption (54 total), if I wanted to avoid inheritance tax, could I ask my parent to give me a smaller share?

Would there be anything wrong with this in the eyes of the NTA if I asked to receive 54 million yen instead of 83? Or, would the NTA still tax me on the hypothetical equal split of 83, even though I didn’t receive 83?
