Haba Castle is thought to have been built by Ogasawara Jūjirō (小笠原重次郎・十二郎*) in the mid-16th century. The Ogasawara were nominal rulers of Shinano Province. The castle was besieged successfully at least twice: first by Takeda Shingen and then several decades later by Oda Nobunaga. Toward the Edo Period the Shiba Clan (柴氏) controlled Habajō. If they continued to do so into the Edo Period then the castle was either abandoned in 1615, as per the One Castle Per Domain Edict, or in the 1630s when their lord, Hoshina Masayuki, moved to a larger domain in Tōhoku.

Habajō is an interesting ruin featuring tall dorui (earth-piled ramparts), deep, wide karabori (dry moats) and kuruwa (baileys). The castle consisted of two principal baileys, the shukuruwa (main bailey) and the ninokuruwa (second bailey). The ninokuruwa was an outer bailey wrapping around the shukuruwa in the west, east and south. To the north the whole castle was bounded by the Tenryū River. Segments of dorui which surrounded the ninokuruwa can still be seen too, now amidst rice paddies. The Japan Rail Iida Line runs through the ninokuruwa. In the northeastern corner of the ninokuruwa is a mound of earth, now containing hokora (mini-shrines), which looks like it could've been a yaguradai (tower platform). The shukuruwa is now the site of a shrine.
