Edo Castle Gates

Edo Castle gates (江戸城三十六見附) are the gates of Edo Castle in Tokyo, Japan. They were placed at crossing points (bridges) of the castle moats. Originally, there were 36 gates. Some remain, such as Sakurada Gate, while others have been completely destroyed. Today, the central quarter of the castle is Tokyo Imperial Palace. Gates on the inner moats are still used as security check points. However, most on the outer moats no longer exist. Some districts in Tokyo have been named after the castle gates.
