Kazumi Kikumoto became interested in yoga because of some health challenges she faced early in life. Yoga helped restore her health, and she decided to explore it more deeply. She travelled to the Indian city of Rishikesh (the yoga capital of the world) and completed her teacher training with Flow Arts Yoga in 2012. She also studied clinical aromatherapy at the Holistic Care Professional School in Tokyo. She has taught at hospitals, nursing homes and corporate settings, and has held many private sessions in person and online, with her efforts helping people be their best selves and shine in their personal and professional lives.
