Rulers
Read from the state’s own English article and its rulers’ articles, where Wikidata names no ruler.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Emperor Taishō | 1914 – 1926 | 12 years | ending not on record | |
| Hirohito | 1926 – 1946 | 20 years | ending not on record | child |
2 rulers, 2 with terms dated as terms, covering 1914 – 1946. Only 32 years of the line are dated - too short for a median. 0 of 1 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
Flags and arms, in order

What led to it, and what came of it
The investigation's own picture: 1 cause the record names and 1 result, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
