Reading the bitterness
「ほろ苦い」 (horonigai) is a Japanese adjective formed from 「ほろ」 (in translation: "slightly") and 「苦い」 (in translation: "bitter"). In dictionary definitions, the 「精選版日本国語大辞典」 (Seisenban Nihon Kokugo Daijiten) explains it as 「いくらか苦みがある。ちょっと苦い」 (in translation: "somewhat bitter; a little bitter"), and the 「デジタル大辞泉」 (Digital Daijisen) as 「ちょっと苦みがある。なんとなく苦い」 (in translation: "a little bitter; vaguely bitter"). The latter gives both 「ほろ苦い味わい」 (a horonigai flavor) and 「ほろ苦い初恋の思い出」 (a horonigai memory of first love) as examples, explicitly placing literal taste and metaphorical uses side by side. The prefix 「ほろ」 (in translation: "slightly") is described by both dictionaries as meaning 「すこし、なんとなく」 (in translation: "a little, somehow"), in the same word formation as 「ほろ酔い」 (in translation: "slightly drunk").
The oldest example of 「ほろ苦い」 cited by the 「精選版日本国語大辞典」 (Seisenban Nihon Kokugo Daijiten) is the line 「下戸の卑怯はほろ苦い顔」 (in translation: "the cowardice of a nondrinker shows in a rueful face") from the haikai collection 「延享廿歌仙」 (in translation: "Twenty Enkyō Kasen") (1745). This describes a person’s expression metaphorically, not the taste of food or drink.
A full-text search of Aozora Bunko returned 53 hits for 「ほろ苦」 (in translation: "slightly bitter") and 29 for 「ほろにが」 (in translation: "slightly bitter"), concentrated in works by authors including 「吉川英治」 (Yoshikawa Eiji), 「種田山頭火」 (Santoka Taneda), and 「太宰治」 (Dazai Osamu) whose copyright terms have expired. This distribution is biased by inclusion criteria (70 years after the author’s death) and is not evidence that the word was especially common in modern literature. Dated examples include the emotional metaphor 「道化た仮面の下を流れるほろ苦がい涙の味」 (in translation: "the bittersweet taste of tears flowing beneath a clownish mask") in a review of a playwright by 「岸田國士」 (Kishida Kunio, published 1925), a line of fantastic fiction describing the taste of liquor, 「一杯のほろ苦き酒あり」 (in translation: "there is a cup of slightly bitter liquor"), by 「牧野信一」 (Makino Shin’ichi) in 「痴酔記」 (in translation: "Chronicle of Intoxication") (published 1931), and a 1933 diary passage by Santoka Taneda that speaks positively of the bitterness of fuki alongside its 「うまさ」 (in translation: "deliciousness").
Words with similar functions occur in other languages. The Italian amarognolo is defined by the Treccani dictionary as 「苦い味だが不快ではない」 (in translation: "bitter-tasting but not unpleasant"); the suffix -ognolo weakens amaro (bitter), and the dictionary itself gives an example meaning 「このリキュールのほろ苦さが好きだ」 (in translation: "I like the slight bitterness of this liqueur"). According to Merriam-Webster, English bittersweet is a compound combining bitter and sweet equally, with the adjective first attested in 1576. Chinese-language tea-culture media use forms such as 「微苦」 (in translation: "slightly bitter"), placing 「微」 (in translation: "slightly") before a word for bitterness, but whether this is a fixed lexical item could not be confirmed here.

Note: Among examples found in this Aozorasearch full-text search (53 hits for 「ほろ苦」 (in translation: "slightly bitter") and 29 for 「ほろにが」 (in translation: "slightly bitter"), mainly from writers whose copyright terms have expired), this is the earliest whose first publication date can be checked in Aozora Bunko’s bibliographic notes. It is an emotional metaphor in a theater review, the taste of tears beneath a clown’s mask, rather than literal taste. Because the search covers Aozora Bunko’s inclusion conditions (70 years after death), it does not mean that no older examples actually exist.

Note: Whereas horo is a prefix attached before the adjective nigai ("bitter") in Japanese, -ognolo is a suffix attached after amaro ("bitter") in Italian — the position is reversed, but both are structurally parallel in having a morphological mechanism that weakens the base bitterness word. No etymological connection (a shared origin) has been confirmed; this is recorded for comparison only. The same word appears in existing disciplinare sensory descriptions (e.g., ingredient-radicchio-treviso-precoce), such as sapore leggermente/gradevolmente amarognolo.

concept-horonigai —is_presented_as→ "The Italian word amarognolo is defined by the Treccani Vocabolario as 『di sapore amaro ma non sgradito』 (in translation: "having a bitter taste but not unpleasant"), formed as a derivative in which the diminutive suffix -ognolo attaches to amaro ("bitter"). The example the dictionary gives is 『mi piace l'amarognolo di questo liquore』 (in translation: "I like the amarognolo [mild bitterness] of this liqueur") — a usage that speaks of bitterness favorably is built into the dictionary's own example."Scope: Merriam-Webster, entry for "bittersweet"
Note: While horonigai ("mildly bitter") and amarognolo are derived by an affix (horo-, -ognolo) that weakens an underlying bitterness word, bittersweet is a compound that joins a bitterness word and a sweetness word on equal terms -- a different mechanism of word formation. The existing entry ingredient-unicum (a Hungarian liqueur that the maker itself calls "bittersweet") is already included as an example of this English expression (linked only; no new entry created).

concept-horonigai —differs_from→ "According to Merriam-Webster, the English word bittersweet is a compound formed by directly joining the 2 opposing words bitter and sweet. Its first known use as a noun is dated to the 14th century, and as an adjective to 1576."Scope: Chinese-language tea-culture media (the same set of examples as the sources for the existing huigan entry)
Note: Wēi ("slight-") is a modifier generally prefixed to many basic-taste words, as in wēikǔ ("slightly bitter"), wēisuān ("slightly sour"), and wēitián ("slightly sweet"); whether it forms a fixed piece of vocabulary strongly tied to one specific word (bitter) — the way horonigai or amarognolo do — could not be confirmed on this access (reaching a Chinese-language dictionary site failed). An unconfirmed point is not proof of absence.

concept-horonigai —is_presented_as→ "Media articles from Chinese-language tea-culture outlets express weak bitterness, in the context of explaining huigan and huitian, through combinations of wēi ("slightly") plus a basic-taste word, as in 『入口时清甜微苦涩』 (in translation: "on first taste it is lightly sweet with a slight bitterness and astringency")."
