Kōsan-ji
Buddhist temple in Hiroshima Prefecture, Japan
Kōsan-ji (耕三寺) is a Hongan-ji school Jōdo Shinshū temple on the island of Ikuchijima in Onomichi, Hiroshima Prefecture, Japan. Founded by the industrialist Kōzō Kanamoto (later Koso Kōsanji) in 1936 in honour of his deceased mother, and with an area of approximately fifty thousand square metres, many of its structures are modelled upon the country's most famous historic temples and shrines. The Hill of Hope (未来心の丘, Miraishin no Oka) is a monument landscaped with five thousand square metres of Carrara marble, weighing some three thousand tons, by Kazuto Kuetani. The Kōsan-ji Museum houses over two thousand items, including nineteen Important Cultural Properties.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Kōsan-ji”, the useful work is to connect “buddhist temple in Hiroshima Prefecture, 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 Aug 2, 2026. The linked authority identifier is Q3201305. VIAF identifies the subject as 151740087. The Library of Congress control number is nr2004018903. Authority coordinates are 34.303, 133.091. 3 of 10 selected statements include explicit references; 6 carry qualifiers and 0 use preferred rank. The first chronological checks are 1936.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
