Kumamoto Castle
castle
Kumamoto Castle (熊本城, Kumamoto-jō) is a hilltop Japanese castle located in Chūō-ku, Kumamoto, in Kumamoto Prefecture. It was a large and well-fortified castle. The castle keep (天守閣, tenshukaku) is a concrete reconstruction built in 1960, but a number of ancillary wooden buildings remain of the original castle. Kumamoto Castle is considered one of the three premier castles in Japan, along with Himeji Castle and Matsumoto Castle. Thirteen structures in the castle complex are designated Important Cultural Property.
History
Kumamoto Castle's history dates to 1467, when fortifications were established by Ideta Hidenobu. In 1496, these fortifications were expanded by Kanokogi Chikakazu. In 1588, Katō Kiyomasa was transferred to the early incarnation of Kumamoto Castle. From 1601 to 1607, Kiyomasa greatly expanded the castle, transforming it into a castle complex with 49 turrets, 18 turret gates, and 29 smaller gates. The smaller castle tower, built sometime after the keep, had several facilities including a well and kitchen.

Why this record matters
The phrase “castle” 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 29, 2026. The linked authority identifier is Q613355. VIAF identifies the subject as 258232307. Authority coordinates are 32.806, 130.706. 2 of 5 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 1960, 1467, 1496 and 1588.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
