Shindofuji is another concept in bio-harmonizing, Japanese bio-hacking. It was originally a concept in Zen Shojin Diet and now has become part of the Japanese natural food movement.
In addition to being the spring equinox, it is the International Day of Happiness tomorrow. Last year I published the Japanese version of the Ikigai Diet, and celebrated it with our local sake called happy. It is Japanese sake and it was brewed locally in Hino Town by an Omi-Hino-merchant called Yao Brewery.
