Map around Gujo-Hachiman Castle. The castle is a short uphill hike from the bus stop at Gujo-Hachiman Jokamachi Plaza, a local tourist shop.
Gujo-Hachiman used to be a separate town (municipality) called "Hachiman-cho" until it merged with several neighboring towns and villages to form the city of Gujo (pop. 38,000) in 2004.
