About Sion Inc.



SION stands for S (South Pole), I (myself), O (Earth) and N (North Pole). 

I used to be unwell and anxious for long time. However, since I started to use sound and the light in my life,  my life has positively changed. I’d love to share this knowledge with other people and be happy together!  So I created Sion Inc.

Let’s celebrate our lives and fill our hearts with love, gratitude and peace.

With lots of love and gratitude,  


Sion Kazu

Sion was in New York at the time of the 9/11 attacks. Her health suffered as a result and in the process of treating herself, she started to investigate the profound healing properties of sound. In 2004, she completed development of the Singing Ring®, opening up a new world of sound therapy. Since then she has been guiding and educating people in her methods throughout Japan and overseas.
