The second song is "愛国行進曲(Aikoku Koshin-kyoku=Patriotic March)", which is a Japanese patriotic song that was made in 1937. This song had been very popular and sung widely until the end of World War Ⅱ. After the end of World War Ⅱ, the United States had wanted the Japanese to abandon their patriotism, and had banned to sing these patriotic songs.
This song would have been the song symbolizes Japan, if Japan had not lost in World War Ⅱ. Most of the Japanese now don't know this song. But this song has a very cheerful melody and beautiful lyrics.
