Inohana Castle is classified as a hilltop castle, and is located in Chiba Prefecture. During the pre-modern age, it found itself within the borders of Shimōsa Province. It is associated with the Chiba clan. Dates in use: 1126 - 1455.

This castle was originally built by the Chiba clan and they managed to remain in control of it for just over 300 years. The current reconstruction dates from 1967 & reflects a much later style of castle than what was originally built. To the northwest there remains a section of earthwork & a dry moat.

As with all Japanese castles, it was built in a location that was relatively protected by its surroundings. The southern & western sides were protected by cliffs and there was a river to the North.

The tombs of the Chiba lords are located in the Dainichi Temple.
