Originally established in 1909, the former branch office of the #Hokkaido government in #Hakodate was restored in 1982, which also saw the construction of a park around it. A notable architectural feature of this building is its portico, comprised of a two-story roof upheld by four Corinthian-style columns and pillars that subtly widen at the midpoint, a design known as the Entasis style.

This Western-inspired edifice holds significant value as it captures the essence of Hakodate during the late Meiji era, as well as embodying the historical trajectory of Hokkaido's development. In recognition of its cultural and historical importance, it was designated as a tangible cultural property by the Hokkaido Government in 1985.

From the early 18th century, this location served as an administrative hub under the control of either the local Matsumae clan or the Tokugawa shogunate. Following the signing of the Treaty of Peace and Amity with the United States in 1855, the port of Hakodate was opened, and the local magistrate's office was reinstated. However, its susceptibility to maritime attacks necessitated a more secure administrative center for #Hokkaido, leading to the establishment of Goryokaku. Consequently, in 1864, the office was moved to this safer location.
