[3] Miyazaki initially studied at Kumamoto Public Middle School, but was put off by his schoolmates' aspirations to become government officials.
He also learned from his brother Tamizō about Land Rights Equalisation and the theories of Henry George and Peter Kropotkin, which would in turn have an influence on his support for a revolution in China.
[14] Miyazaki ultimately left Christianity while in Nagasaki after studying theology, philosophy and sociology, deciding that he would instead but his faith in rationalism.
He was helped in this decision by a letter from his brother Yazō and friend from Waseda, Fujiyama, stating that they too left the faith for similar reasons.
He finally abandoned supernaturalism outright when he met an eccentric Swedish beggar named Isaac Abraham, who shocked Miyazaki by warning him against religion and that even in America and Europe, the home of liberal ideas, many people still suffer in poverty.
Isaac's personal philosophy of anarchism involved a fanatical glorification of nature, which included open defecation in local fields.
[15] After falling deeply in love with Tsuchi, Miyazaki gradually developed guilt as he felt an early marriage would limit his ability to carry out his ambition of ending poverty around the world.
In 1891, Miyazaki travelled to Shanghai on the Saikyō Maru to learn Chinese language and customs, but returned to Japan shortly after to seek money he had loaned a Nagasaki eccentric.
Determined to make progress on his plans with Yazō, Miyazaki decided to meet with Korean revolutionary Kim Ok-gyun, who was in exile in Japan at the time following the failed Gaspin Coup.
During their meeting, Kim praised Miyazaki's plan to move to Shanghai and agreed that China would be the key to the future of Asia.
[20] Between his trips to Siam, he also got news from his brother Yazō in Yokohama who had made contact with Chan Siu Bak, a revolutionary who had fled China after the failed Guangzhou Uprising.
While in Tokyo, he met with future Prime Minister Inukai Tsuyoshi who advised him to give up his plans in Siam and focus on China.
[22] Before leaving for China, Miyazaki met with Chan Siu Bak who taught him about the Chinese revolutionary movement and told him about his comrade Sun Yat-sen, who was being imprisoned in London at the time.
"[23] Tōten Miyazaki would later register Sun for his safety under the name Nakayama (中山) at the "Crane Hotel" (對鶴館).
Following this, he met with Kang Youwei, a central figure in the Hundred Day's Reform, which had now failed and resulted in the house-imprisonment of the Guangxu Emperor.
However, Kang mistakenly believed that Miyazaki was planning to assassinate him, and reported him to the British authorities in Singapore to have him arrested and deported.
[26] Miyazaki was arrested alongside a Japanese associate, Koshichirō Kiyofuji (清藤 幸七郎) on 6 July 1900, and spent a number of days in prison before being exiled from Singapore for a period of five years.
[27] He left Singapore and headed for Hong Kong with a group including Sun Yat-sen, but found that his exile was also enforced by the British authorities there.
In 1906, he also helped establish a journal with others such as Saburo Wada, secretary of Liberal Party founder Itagaki Taisuke, Shu Hirayama, and Nagatomo Kayano.
The "Revolutionary Review" was published for 10 volumes from 25 March 1907 to 5 September 1907, with the journal supporting Sun Yet-sen's 1911 Xinhai Revolution.
In 1917, he visited Hunan, China to give a lecture about how the Japanese helped to put an end to the white westerners' control of Asia.
The Nanjing Historical Remains Museum of Chinese Modern History has bronze statues of Sun and Miyazaki placed alongside each other.
