Cause and Context
Usui Died Suddenly While Still Teaching
The best short answer is that Mikao Usui died of a stroke. Some sources use the broader phrase sudden illness because the memorial stone does not name a medical diagnosis.
He died in Fukuyama, not at his Tokyo memorial site. This matters because it shows he was actively traveling and teaching when his life ended.
Usui's death came only four years after his 1922 Reiki awakening. That compressed timeline explains why his students became so important to Reiki's survival.

Medical Wording
Stroke or Sudden Illness?
The memorial stone gives dignified, general wording: Usui became ill and passed away. It does not name a modern diagnosis.
Later Reiki historians commonly identify the cause as a stroke. That is the most direct answer for readers asking how he died, while 'sudden illness' is the more cautious wording from the memorial record.
