Azuchi Castle
It was originally built by Oda Nobunaga to join Azuchi Castle to Kyoto. After the Battle of Sekigahara, Tokugawa Ieyasu used it for going to Kyoto, so it was considered an auspicious road. It served as a sub-route of the Nakasendō, connecting Toriimoto-juku with Yasu village (between Musa-juku and Moriyama-juku). At , the route only skipped over three other post stations. Staying closer to Lake Biwa, the route went through the present day municipalities of Hikone, Azuchi, Ōmihachiman and Yasu in Shiga Prefecture.
