The Yellow Wave
From Wikipedia:
"Shiel returned to contemporary themes in The Yellow Wave (1905), an historical novel about the Russo-Japanese War of 1904–1905. The novel was a recasting of Romeo and Juliet into the ongoing war with leading families of the two nations standing in for the feuding Capulets and Montagues of Shakespeare's play. Shiel modelled his hero on Yoshio Markino (1874–1956), the Japanese artist and author who lived in London from 1897–1942."
