Chizuko Mifune

She was introduced to hypnosis by her brother-in-law, and allegedly developed her powers at the age of 24 by practicing breathing and meditation exercises.

[1][2] Tomokichi Fukurai, Assistant Professor of Psychology at the University of Tokyo, was deeply interested in the supernatural and desired to validate extra-sensory perception.

Fukarai's supernatural interests were heavily criticized by his colleagues, but he was convinced Mifune's powers were genuine when he privately tested her in April 1910.

A second, public test was conducted by Tokyo University president Baron Yamakawa Kenjirō on 15 September 1910.

[1][2] A modern researcher, Rodger Anderson has noted that the experiments were not properly controlled as Mifune "was often left alone with the test envelope, or insisted on turning her back to witnesses when attempting to psychically probe its contents.
