She graduated from nursing school in 1897 and after touring Europe and studying hospitals there, was appointed as the first commoner to direct the Japanese Red Cross.

In 1920, she led a successful campaign to assist Polish orphans who had become refugees in Siberia and that same year was one of the inaugural recipients of the Florence Nightingale Medal.

She completed all the requirements for the women's communication undergraduate degree being offered through the Woman Science Magazine [ja] (Japanese: 女学雑誌) and received a diploma in January 1891.

[2] In 1894 the decision was made by the Red Cross to send nurses in the midst of their training to help with relief efforts when the Sino Japanese War broke out.

Hagiwara was sent and received praise for her service; she was specifically requested to help with relief efforts in Aomori, Iwate, and Miyagi Prefectures when the 1896 Tsunami caused civil disasters in those areas.

Preceding the Russian Revolution, Poles, who had been exiled to Siberia or sought refuge there during World War I, numbered around 20 million people.

[2] Anna Bielkiewicz and Józef Jakóbkiewicz, of Vladivostok had formed the Polish Rescue Committee, began collecting orphans from throughout the area and petitioned Western countries for help.

After providing them with health services, as well as shoes and clothing, the JRC helped transport the children to Yokohama, where they were sent to Polish Relief Organizations in Seattle, Washington.

[11] Hagiwara attended the 1929 Congress of the ICN held in Montreal[4] and that same year finally was able to found the Nursing Association of the Japanese Empire.
