Background
Ryūrō was born in Nagasaki, Buzen province (present-day Nagasaki prefecture), to a samurai-class family originally from Kurume domain. His father had been trained as a doctor, and was in Nagasaki studying western medicine at the time of the Meiji Restoration.
Career
He is credited with the creation of the tragic novel (悲惨小説, hisan shōsetsu) genre in Japanese literature. His real name was Hirotsu Naoto. Under the new Meiji government, he became a diplomat, and was involved in the Seikanron issue between Japan and of Korea.
Ryūrō was sent to Tokyo in 1874 to study the German language, and subsequently enrolled in the medical preparatory school of Tokyo Imperial University, but left without graduating in 1877.
Around this time, he read the Chinese literature classic Outlaws of the Marsh and the Japanese fantasy novel Nansō Satomi Hakkenden by Kyokutei Bakin. These works, combined with the death of his father, formed a turning point in his life, and he decided to abandon his secure career in the government for life as a writer
In 1899, Ryūrō met Ozaki Kōyō, and joined his literary group Ken"yusha. These were the first of a new genre in Japanese literature, the "tragic novel", which he created.
His plots are typified by an inexorable progression of the protagonist through a series of pathetic and wretched experiences towards destruction dictated by an inflexible fate.
His most famous work, Imado Shinju (Suicide at Imado), was published in 1896. Ryūrō retired from writing in 1908, and died of a heart attack in 1928. His grave is at the Yanaka Cemetery in Tokyo.
Views
Heavily influenced by earlier Edo period gesaku writing, his stories are filled with improbable or incredible events, melodrama, romanticism and rather wooden characterization.
