Kyushu
third largest island of Japan
Kyushu (九州, Kyūshū; pronounced [k̟ʲjɨ́ɨ̀.ɕɨ̀ɨ̀] , lit. 'nine provinces') is the third-largest and most southerly of Japan's four main islands. In the past, it has been known as Kyūkoku (九国, "Nine Countries"), Chinzei (鎮西, "West of the Pacified Area") and Tsukushi-no-shima (筑紫島, "Island of Tsukushi"). The historical regional name Saikaidō (西海道; lit. West Sea Circuit) referred to Kyushu and its surrounding islands. Kyushu has a land area of 36,782 square kilometres (14,202 sq mi) and a population of 12,382,121 as of 2025, a population size similar to New Guinea or Cuba.
There is a theory that Kyushu was in ancient times home to its own independent dynasty, where a unique, southern-influenced culture and tradition distinct from that of Honshu flourished.
In the 8th-century Taihō Code reforms, Dazaifu was established as a special administrative term for the region.
Geography
The island is mountainous, and Japan's largest active volcano, Mount Aso at 1,591 metres (5,220 ft), is on Kyushu. There are many other signs of tectonic activity, including numerous areas of hot springs.
The public source identifies “Kyushu” as third largest island of Japan. This brief keeps that definition visible, then builds a research path around Kyushu, third and largest.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Kyushu”, the useful work is to connect “third largest island of Japan” to the records capable of establishing context and consequence.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q13987. VIAF identifies the subject as 246095633. Authority coordinates are 33.000, 131.000. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025.
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.
