Following Senju-juku (Adachi Ward, Tokyo), Soka-juku was the second post town on the old Nikko Kaido Road from Tokyo (Nihonbashi) to Nikko in Tochigi Prefecture. However, no original buildings from Soka-juku remain.
Part of the Nikko Kaido road remains, and a few monuments mark the location of the Honjin VIP lodges and road marker. This is a scale model of Soka-juku displayed in the local history museum.
