About the song and rowing route...　この歌について（日本語解説）

Shiga Prefecture's most famous and beloved song is called Biwako Shuko no Uta (琵琶湖周航の歌) or "Lake Biwa Rowing Song." I have rendered this song into both pictures and English, according to my own imagination and interpretation.

First composed in 1917 by a bunch of college students from Kyoto, the song has been recorded by many famous Japanese singers and groups. In 1971, it became a major nationwide hit with singer Tokiko Kato's rendition. Today, the song remains a favorite among choir groups in Japan, and a choir singing contest is held for the song every June (since 1997) in Imazu, the birthplace of the song in the northwestern corner of Lake Biwa.

Shiga Prefecture also has stone monuments dedicated to each of the six verses. There's even a museum (Biwako Shuko no Uta Shiryokan) in Imazu dedicated to the song. Okaya city on the shores of Lake Suwa in Nagano Prefecture, the birthplace of the song's composer, Taro Oguchi (小口太郎) (1897-1924), also has a song monument and bronze statue of him.
