Operated by Shiga Prefecture's Board of Education, the Uminoko "Biwako Floating School" is an educational boat going on overnight voyages year-round on Lake Biwa, taking Shiga's 5th graders.

This first and original Uminoko ship was in operation from Aug. 2, 1983 to spring 2018 when it was retired. It was replaced by a new Uminoko ship (same name) in May 2018. The following photos are of the old Uminoko ship inside and outside when it was open to the public in Aug. 2010.
