The Date
1922 Is the Key Year in Reiki History
The standard Reiki timeline places Usui's discovery in 1922. That is the year of the Mount Kurama retreat, the awakening experience, and the beginning of his public Reiki work.
The exact day is not as secure as the year. Reiki lineages often emphasize the 21-day discipline rather than a calendar date. The historically useful answer is 1922, with Mount Kurama as the setting.
The date matters because it shows how brief Usui's teaching period was. From discovery in 1922 to death in 1926, he had only about four years to develop the system, teach students, and leave a lineage behind.

Late-Life Discovery
Usui Was Not a Young Man When Reiki Began
Usui was born on 15 August 1865. If the discovery happened in 1922, he was about 56 or 57 depending on the month. That makes Reiki a late-life flowering, not a youthful invention.
This is important because it changes the feel of the story. Reiki came after decades of work, reading, practice, disappointment, and searching. The mountain retreat was a breakthrough, but not a shortcut.
