Discovered this a couple of days ago and I'm solidly meh on the song but damn the stage is absolutely iconic !
Mikasa (三笠) is a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. Named after Mount Mikasa in Nara, Japan, the ship served as the flagship of Vice Admiral Tōgō Heihachirō throughout the Russo-Japanese War of 1904–1905, vs Russian War!
