官軍行進曲 (Kangun kōshinkyoku) - Japanese Military Song

Found another Boshin war era marching song. I don't really have much to say but it's very... catchy I may say. I don't have any information on this song, the description of where I found it linked to the "Japan First" website.. which says a lot to me about the individual who uploaded it. Judging from the audio, it's probably from a movie. If you have any information, I would like to know
