@CAM, thanks for the considered response and the links.

your questions all seem to concern the basic inheritance-tax deduction
Initial questions, yes
Initial forays into understanding transnational inheritance!
Assuming I've understood correctly, your answers confirm that the determination of basic deduction is both simple and potentially favourable to transnational inheritances.
A. Lots of statutory heirs? Higher basic deduction (than if fewer heirs existed).
B. Only a portion of the estate 'visible' to Japanese tax authorities? Basic deduction (including the bit based on number of heirs) still applies, even on a portion of the overall estate, and even when not all of the heirs have Japanese tax obligations.
In A, the whole picture (ie entire cast of statutory heirs) is considered, irrespective of J tax obligations.
In B, a partial picture (ie estate visible to J tax authorities) is considered.
Interesting consequences (as northsaver comments).
In an extreme case:
Overseas decedent. (No ties to Japan; all assets overseas.)
Estate value 1,000m (10 oku).
10 statutory heirs; equal split (100m = 1 oku each).
Only 1 heir with J tax obligations.
Basic deduction of 30m + 10 x 6m = 90m J tax due on 10m, but probable that foreign tax credits would cover the bill.
Thus, minimal or no J IHT actually paid on 1 oku inheritance.
Presumably rare to have 10 statutory heirs. Less rare to have 4:
Overseas decedent. (No ties to Japan; all assets overseas.)
Estate value 200m (2 oku).
4 statutory heirs; equal split (50m).
Only 1 heir with J tax obligations.
Basic deduction of 30m + 4 x 6m = 54m
50m inheritance entirely free of J tax (and indeed reporting requirements?).
In both of the above cases, substantial portions of the basic deductions are due to heirs with no visibility to J tax authorities. Well, to qualify, they
are 'visible' for the calculation of the basic deduction, then slip back into the ether.
I think the wiki, r/Japanfinance and this forum are great resources.
I think IHT is complicated. Especially transnational inheritance. The IHT wiki article was one of my first ports of call.
As one discussion on reddit revealed, siblings (/other cases of multiple statutory heirs of the same ranking) can have quite an effect on Japanese and transnational IHT.
Thanks again for answers.
