Omura graduated from the Jikei University School of Medicin Tokyo JAPAN in 2004. After completing a short-term exchange at the St. Thomas Hospital in the United Kingdom as an exchange student with the selected grant from the Jikei University.

Since 2009, he has been admitted to the otorhinolaryngology department the Jikei University School of Medicine. Dr. Omura reports seventeen novel surgical techniques out of over 70 international papers and has transmitted it's techniques of endoscopic approach to tumors in the nasal cavity, skull base, to the world as well as Japan. His operational number of endoscopic approach for sinonasal malignant tumor is the highest in Japan and he has been invited as an operator from national cancer center Japan, and many universities.
