Geography
Kujūkuri Beach extends in the shape of an arc from Cape Gyōbumi in Asahi to the north to Cape Taitō in Isumi, Chiba Prefecture to the south. The beach is relatively straight, in contrast to the typically irregular coastlines of Japan. The tides and the Kuroshio Current create sand deposits along the length of the beach which form sand dunes of 4 metres (13 ft) to 6 metres (20 ft). Kujūkuri Beach has no reef.
The coastal region of the beach is the north-eastern end of Kuroshio Current influence in Japan.
Municipalities
Kujūkuri Beach extends across ten municipalities in Chiba Prefecture.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Kujūkuri Beach”, the useful work is to connect “protected area” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q996212. Authority coordinates are 35.529, 140.452. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation.
