Shibukawa Hironao was a late [[Edo period]] scholar of [[Japanese calendar|calendrics]] and [[Rangaku]]. As an official in the Tokugawa shogunate, he played a role in shaping the [[Tenpo Reforms|Tenpô Reforms]].
Born in [[Edo]] the eldest son of [[Shibukawa Kagesuke]] in [[1815]], he was named apprentice to the [[Tenmongata]] (chief astronomer and calendrics master) of the [[Tokugawa shogunate]] in [[1831]]. With the aid of his father, he edited or compiled a number of works on calendrics. In [[1842]], he was named ''[[shomotsu bugyo|shomotsu bugyô]]'' (Documents Magistrate).
Studying Rangaku and English, Shibukawa came to be assigned by the shogunate to a variety of other tasks; in [[1844]], he translated a letter to the shogun from King Willem II of the Netherlands.
Shibukawa played a role in drafting or implementing the [[Tenpo Reforms|Tenpô Reforms]] alongside [[Mizuno Tadakuni]], [[Torii Yozo|Torii Yôzô]], and [[Goto Sanemon|Gotô San'emon]], but following Tadakuni's death, Shibukawa was exiled in [[1845]] to [[Usuki han]] in [[Kyushu]]. He died there on [[1851]]/7/25, and the shogunate dispatched an official to investigate the circumstances of his death.
