Gujo-Hachiman Castle's tenshu main tower. Reconstruction built in 1933. The original castle was dismantled in 1870 when the samurai system was abolished. Only the stone walls and foundations remained.

This reconstruction is unusual because it was built using wood instead of concrete. This is in fact Japan's oldest reconstructed main castle tower made of wood.

Entrance to the castle tower can be seen on the right. Small admission charged.
