The temple complex is post-war reconstruction.
This temple is known for Shibarare Jizo-son, which can be translated as "bound Jizo-son."

Hondo is the main hall of a temple. Here in Nanzoin, Gautama Buddha, founder of Buddhism, is enshrined in Hondo.
Shotoku-Taishido enshrines Shotoku Taishi (574-622), a crown prince known for his protection for Buddhism.

Jizodo enshrines Jizo Bosatsu, a Buddhist deity widely regarded as a god of mercy.

Shibarare Jizo, literally translated "bound Jizo", is a stone statue of Jizo Bosatsu bound with ropes. When you make a wish to this statue, you bind this statue with a rope, and when the wish is fulfilled, you unbind it.
