The Gokasho Kondo is a region with strong links to the Omi Merchants, and has been designated a Preservation District for Groups of Traditional Buildings, as well as a Japan Heritage site in 2015. Walking these fascinating streets will reveal a refined atmosphere, with clean water flowing through the waterways where vari-colored carp swim elegantly. In the Kondo region there are also three Omi Merchant houses open to the public, allowing you to see how these famous businessmen lived.
