The ships sailed from Ushibuka through the Inland Sea to Osaka via Nagasaki. Then some ships (Kitamae-bune) left Osaka back through the Inland Sea and into the Sea of Japan for Hokkaido via Nigata and other ports. Here they took on local dance and songs incorporating them into the original Haiya melody.
Like this, songs originated in “Ushibuka Haiya-Bushi” have been passed down from generation to generation in various areas from Kagoshima in the south to Hokkaido in the north. Sado Okesa and Awa Odori are representative of them.
