When the Satake clan destroyed the Oda in the Tensho era, the temple lost their patronage; in the Edo period it received a shuinjo from the Tokugawa shogunate. The Yakushi Hall was rebuilt in the Keian era.

Tojo-ji stands in the eastern part of Tsuchiura, in the Tojo-ji district that carries its name. The temple grounds are reached from the surrounding rural roads, and the Yakushi-do hall rebuilt in the Keian era is the main structure a visitor sees. The temple is a single independent Shingon-lineage foundation, not part of a larger pilgrimage network.

The temple holds a wooden seated statue of Kōchi Shōnin, a prefectural cultural property, along with a stone lantern, a boundary stone (kekkaishi) and a group of sutra mounds (kyōzuka). The kekkaishi marked the temple's sacred boundary, and the kyōzuka are burial mounds for buried sutra copies.
