Ueda Castle is located on a hill overlooking a branch of the Chikuma River at the northeast edge of the Nagano plain, which forms part of its southern defences and acts as a moat.

The Central Bailey (Hon-Maru) [1] originally had seven two-story yagura, but no donjon and was protected by a moat as well as stone ramparts.
The Central Bailey is also surrounded by a Second Bailey (Ni-no-Maru) [2], also with moats and earthen ramparts.
 The adjacent Third Bailey (San-no-maru) [3], had additional yagura, of which only the foundation bases remain, and  contained the main residence of the daimyō [R] (which was also protected by a moat), gardens [G] and work area [A], and the main gate (Ōtemon) of the castle [H].
Most of the area of the former Third Bailey is now occupied by the Ueda High School.
