He was an assistant to Julius Scriba, a professor of surgery at Tokyo Imperial University, and later became a student of Jan Mikulicz-Radecki, a German-Polish-Austrian surgeon.

Miyake served as the president of the Japan Surgical Society and was a long-time friend of theoretical physicist Albert Einstein.

[2] Miyake described this case of a patient with a fracture of the left temporal bone and right-sided hemiparesis, who improved after the removal of the inwardly displaced skull fragments, in the Tokyo Medical Journal in 1893.

[1] Dissatisfied with the state of medical services in the city, he decided to pursue further studies in Germany, like many other Japanese doctors of the time.

Hearing about the scientific achievements of German-Polish-Austrian surgeon Jan Mikulicz-Radecki, who was a student of Theodor Billroth, he decided to travel to Wrocław by train to seek collaboration.

In 1908, three years after the funeral, Henriette von Mikulicz-Radecki gave Miyake her husband's death mask, his portrait by Läwen, and manuscripts.

[10] After the war, Miyake's son, Hiroshi, found the mask and made several copies, sending the original by diplomatic mail to Mikulicz's grandson, F. Anschütz.

In a letter dated 27 April 1976, Hiroshi wrote that the mask copies were given to surgical clinics in Japan to be kept "as a memento of the father of our surgery".

In 2002, one of the copies was presented to the Surgical Clinic of the Medical Academy in Wrocław by Professor Miyake's great-granddaughter, Sumiko Hiki.

[6] In October 1922, on his return voyage to Japan after his third visit to Europe, Miyake met theoretical physicist Albert Einstein.

To this end, he visited surgical clinics in Europe and America, collecting signatures for a petition to change the society's decision.

[6] He obtained support from, among others, the Mayo brothers (William James and Charles Horace) from the clinic in Rochester, Evarts Ambrose Graham from St. Louis, and Harvey Cushing from Boston.

[6] In 1928, Miyake was recommended by Ferdinand Sauerbruch, a former colleague from the clinic in Wrocław, for a position on the editorial board of the German journal Deutsche Zeitschrift für Chirurgie.

When allied bombing began to threaten the family, his son Hiroshi decided to flee from Ashiya to Tottori and in May 1945 took his parents to his home in Okayama.

[8] On the night of 29 June, two days before the planned departure to Tottori, Hayari Miyake and his wife Miho were killed during the American carpet bombing of Okayama [ja].

[1][4] After the war ended, Hiroshi Miyake informed Albert Einstein (residing in Princeton) about the death of his parents.
