CHIKOTO is a practitioner from Japan who identifies with the tradition of Fushoku (不食), a Japanese term for the practice of abstaining from food. They describe themselves as a "carefree Fushoku practitioner." CHIKOTO's central claim is that they live by consuming both "material and non-material" substances for sustenance. They explicitly identify this non-material source as Prana.
In addition to consuming Prana, CHIKOTO also claims the ability to see it. In one of their writings, they stated that they had been practicing Fushoku for one year. As a result of this year-long practice, CHIKOTO reported experiencing "dramatic physical changes." The provided source material does not specify the nature of these changes or include any third-party observations or studies of their practice.
