永遠に心の中に eien ni kokoro no naka ni Forever in My Heart
永遠に心の中に (eien ni kokoro no naka ni) says forever in the heart, and leaves whose heart unsaid. In the National Diet Library's full text it stands on one page before 1946, of 1927. There a Sado Island teacher hopes a class motto will lodge forever in the pupils' hearts.
Abstract
永遠に心の中に, forever in the heart, sets 永遠, the Japanese word for eternity, as the adverb forever before 心の中に, in the heart, and names no possessor, so whose heart it is the sentence leaves open; it has no author. In the National Diet Library's full text, searched across every access tier, it stands in one book before 1946, the record of a national conference of teachers of December 1927, where 田邊譽三郎 of a school on Sado Island hopes that a class motto will lodge forever in the pupils' hearts. The form with my, 永遠に私の心に, is older in the same index, from a 1916 translation of Elisabeth Förster-Nietzsche's book on her brother, and after the war 永遠に心の中に is found in grief, with nothing around it in the snippet of a 1962 book on the loss of a daughter, and closing a pupil's letter in a 1978 magazine whose next words name 13 December, the day Obara Kuniyoshi died, as a sad day. In English, for ever in my heart is a formula of memorial notices by 1902.
Overview
The sense. Standard written Japanese. No dictionary has the phrase, so it is read from its words: 永遠 is the noun eternity and, as 永遠に, the adverb forever [1]; 心の中 is one's heart, one's inner thoughts in JMdict [2]. The phrase is forever, in the heart. Japanese can name the heart's owner, as in 永遠に私の心に, forever in my heart, or leave it to the sentence, and this phrase leaves it. 永遠 has a second sense, existence outside time, which enters the dictionaries from the philosophers' vocabulary of 1881 [1], and the Catholic hymnal of 1916 uses it of the eternal Father (the library's text layer) [3].
The words. 永遠 eien. デジタル大辞泉: いつまでも果てしなく続くこと。時間を超えて存在すること, continuing without end; existing beyond time, with the examples 永遠に残る名曲, a song that will last forever, and 永遠のスター. 精選版日本国語大辞典 gives the same first sense with its synonyms 永久, とこしえ, 永劫, and its first citation: 永遠無疆の福を望むことなり, to hope for a blessedness without end, in 西国立志編 (1870–71), Nakamura Masanao's translation of Self-Help; the second sense, existence outside time, is cited from the 哲学字彙 of 1881 as the entry Eternity 永遠; the dictionary names the 書経 as an older source in Chinese [1]. 心 kokoro, the heart as the seat of feeling and mind, cited from the 古事記 of 712 [4]; 中 naka, inside [5]; 心の中, inside one's heart; in one's mind [2].
The text in English. Forever is an adverb and 永遠に does the same work; 永遠 alone is also the noun eternity, which English keeps separate. The bilingual dictionary gives 永遠 as eternity; perpetuity; permanence; immortality and no more [6]. English must name the heart's owner where the Japanese need not, so forever in my heart is a rendering that chooses one. In English the phrase has a home in mourning: the London Jewish Chronicle of 7 November 1902 prints, under In Memoriam, a notice for a mother that ends Gone from my sight but for ever in my heart [7].
The historical record
1927. A class motto, on Sado Island. The phrase has one book before 1946 in the National Diet Library's full text, searched in every access tier, oldest first [8]. It is the record of the twenty-ninth national conference of elementary teachers, published in December 1927 [9]. 田邊譽三郎, of the 眞野 elementary and higher school in Sado county, Niigata, reports on his school under the title 永遠性教育並びに郷土化實業化せる我が校高等科經營の實際, education for eternity, and the running of our higher course, made local and vocational. Under the heading 級訓による永遠的信念の涵養, the cultivation of an eternal conviction through the class motto, the report hopes the motto will work like this: 永遠に心の中に信念化して宿り彼等に正しき方向を示すやう。そして卒業後の七轉八苦の中に常に甦へる愛の鞭であり力の泉でありたい, that it may lodge forever in the heart as a conviction and show them the right direction; and may it be a whip of love and a spring of strength, ever reviving in the struggles after graduation. The school printed the motto on postcards and calendars and in lithograph and gave it to the pupils: 之をはがき月暦に刷り又石版刷りにして與ふ [9].
1916 to 1942. The form with my. 永遠に私の心に is in thirteen books before 1946 in the same index [8]. The oldest is a 1916 translation, by 磯部泰治, of Elisabeth Förster-Nietzsche's book on her brother; in the index's snippet she writes that at Nietzsche's burial Peter Gast spoke words that would be stamped forever in her heart [10]. A student coming down the Yangtze in 1926 writes that a fearful revelation of the sky 永遠に私の心におのゝいてゐる, trembles forever in my heart [11]. Before the war the sentence of mourning is a longer one: in memorial volumes of 1937 to 1944, read in the index's snippets, the dead are said to live forever in the writer's heart, in the form 永遠に私の心の中に with a verb after it [8].
1948 and after. In grief. After the war 永遠に心の中に is in some 165 books of the same index, in novels, memoirs and school magazines [8]. Two of them use it the way the scroll is used. In 1962 成田清治's book on losing a daughter to cancer, 『永遠に愛し』, has the phrase with nothing before or after it, in the index's snippet [12]. In February 1978 the magazine 『全人教育』 prints a fifth-grader's letter to a teacher wished a long life in heaven, which closes with 永遠に心の中に and the child's name; in the index's snippet the next words call 13 December a sad day and name Obara Kuniyoshi 小原國芳, the founder of Tamagawa Gakuen, who died on that day in 1977 [13][14].
What is not a source. The phrase has no author. The 1927 report is its earliest page in the library's full text, not its origin; the history does not lend the scroll the teacher's motto, the translator's grief or the pupil's.
A reading
The same sentence as 永遠に私の心に, less my, and the library holds both in about equal numbers, so the choice is not between correct and incorrect Japanese. What changes is whose heart. With 私の the sentence belongs to one person. Without it the heart can be the writer's or a whole class's, which is how the teacher on Sado used it in 1927, and how a reader hanging the scroll can use it now: for one person remembered, or for everyone who remembers them. 永遠 was made for eternity and has not lost that size, so the heart it is set beside is held a little higher than the English holds it.
Notes
One book is scoped. One page before 1946 is a statement about the National Diet Library's full text, searched on 10 October 2026 in every access tier, oldest first, for 永遠に心の中に (166 books) and 永遠に私の心に (147 books). The library's public-domain subset and its local mirror agree. The postwar count is the index's, and 67 of its 166 books are from 1990 or later.
Snippets. The 1916, 1962 and 1978 books are read in the library's snippet only: the first because its page images are not served outside Japan, the others because they are served only in Japan. Their sentences are described here, not quoted, except the phrase itself.
