During the Boshin War of 1868, Hayashi led his domain's forces in support of the armies of the former shōgun, and then the Ōuetsu Reppan Dōmei.

During the Meiji period he worked in various occupations, before working for the government. In the Meiji period, his family was ennobled as part of the kazoku system. For a time he also served at Tōshō-gū in Nikkō. Hayashi lived well into the 20th century, and was famous as "the last daimyō". He died in early 1941, in an apartment run by his daughter Mitsu.
