Nishikata Castle
castle in Tochigi Prefecture, Japan

Nishikata Castle (西方城, Nishikata-jō) was a yamajiro-style Japanese castle located in the Nishikatahonjō neighborhood of the city of Tochigi, Tochigi Prefecture, in the southern Tōhoku region of Japan. The ruins were designated a National Historic Site in 2022.
Overview
Nishikata Castle was built from the eastern foot to the summit of the 221.3-meter Mount Shiroyama at the eastern end of the Ashio Mountains. It comprises eight enclosures, separated north and south by earthworks, moats, and earthen bridges. The history of the castle is uncertain, but it is believed to have been built on the Kamakura period in 1293 by Utsunomiya Kageyasu, who took the name "Nishikata" from the local place name. During the tenure of Nishikata Tsunayoshi, Toyotomi Hideyoshi attacked the Odawara Hōjō clan at the Siege of Odawara (1590). Tsunayoshi, who refused the summons the pledge fealty to Hideyoshi, had his territory confiscated. The former Nishikata territory was given to Yūki Hideyasu. However, after the Battle of Sekigahara in 1600, the Yūki clan was transferred to Echizen Province, and the former Nishikata lands were given to Fujita Nobuyoshi (becoming the 15,000 koku Nishikata Domain). Fujita Nobuyoshi constructed a new castle, commonly known as "Nijō Castle," at an elevation of about 150 meters on the southeast side of the Nishikata Castle ruins.

Why this record matters
The phrase “castle in Tochigi Prefecture, Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q121354289. Authority coordinates are 36.474, 139.720. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2022, 1293, 1590 and 1600.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
