開陽丸 / Kaiyou Maru

開陽丸（位於江差町）是將以前的軍艦重新改裝成博物館（需門票），如果只參觀外觀的話免費。是在1866年時由荷蘭所建造的船艦，現代人將開陽丸修復後停泊在港口。當時是由德川家的將軍所統治的時代。之後迎來了天皇所治理的明治時代。德川家的家臣便奪取了開陽丸並逃亡到北海道。然而抵抗並沒有持續很久，最終開陽丸在江差外海觸礁而沉沒。

Kaiyou Maru (Esashi Town) is a paid historical museum housed in an old battleship. Visitors can of course admire the vessel from outside for free, and also take in the view of the whole harbor. The boat was made in the Netherlands in 1866, but since being renovated has been moored in the harbor. The era when this ship was made was the Edo Period, when the Tokugawa Family governed as Shogun (General in English). Later, the Tokugawa Family ceded political power to the Emperor, seeing the beginning of the Meiji Period. In the early Meiji period, Tokugawa loyalists took this battleship and delivered it to Hokkaido, but the ship was sunk off Esashi Town.
