Harada Kai, born Harada Munesuke (1619-1671), was a senior retainer of the Sendai domain and the resident lord of Funaoka Castle, in what is now the city of Shibata. According to Japanese sources, he was a maternal grandson of Date Masamune. He headed the Harada house from childhood and held a stipend of 4,380 koku. In 1663 he became bugyō (chief councillor) of the domain. His name is linked to the Kanbun Incident (1671), the culminating episode of the troubles within the Date house. Summoned to the residence of the senior councillor Sakai Tadakiyo, he killed Date Muneshige before being mortally wounded, and his family was annihilated. Long regarded as a traitor, he was rehabilitated by Yamamoto Shūgorō’s novel “Momi no ki wa nokotta”, which turned the park of Funaoka Castle into a site of memory.
The Harada house settled at Funaoka Castle in 1615. This site on Mount Shiho controlled the pass formed by the Shiroishi River and the Ōshū Kaidō, south of the Sendai domain. Harada Kai resided there until his death in 1671; after his family was annihilated, the fief passed to the Shibata family in 1681.

The NHK series based on the novel “Momi no ki wa nokotta” popularises his figure and the Funaoka site.
Traditional historiography cast Harada Kai as the villain of the troubles within the Date house. Yamamoto Shūgorō’s novel “Momi no ki wa nokotta”, by contrast, portrays him as a loyal vassal who sacrificed himself to save the domain. Its adaptation by NHK in 1970 made the park of Funaoka Castle a place associated with this figure, marked by Miyagi Prefecture around the novel’s cedar tree.
