Irop'a
Korean textbook on the Japanese language
The Irop'a (Korean: 이로파; Hanja: 伊路波) is a Korean textbook of the Japanese language published in 1492.
It is a source on the phonology of Late Middle Japanese.
The Irop'a is named in official Korean lists of textbooks for Japanese dated 1430, 1469 and 1707.
It was presumably revised after the introduction of the Hangul alphabet in 1446.
Only one copy of the Irop'a is known today, an edition printed in 1492.
This copy was in the collection of Kanbara Jinzō, president of Kagawa University, and first publicized in 1959.
It is now held by the university library.
The work begins with four forms of the Japanese syllabary, each in the order of the Iroha poem: hiragana, two forms of mana (cursive Chinese characters), and katakana.
Each hiragana syllable is accompanied by a transcription of its sound using Hangul.
The hiragana syllabary is followed by Hangul transcriptions of 16 Japanese words, represented by Chinese characters: 京 'capital', 上 'above' and the numerals 1 to 10, 100, 1000, 10,000 and 100,000,000.
This brief starts where responsible research should: with the source description of “Irop'a” as korean textbook on the Japanese language. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as korean textbook on the Japanese language. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 1, 2025. The linked authority identifier is Q96382881. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1492, 1430, 1469 and 1707.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
