Lastly, "kun'yomi" readings for characters can be annotated with "furigana". Normally furigana are only used for uncommon kanji or unusual readings. This sentence's only uncommon kanji is "hisa(gu)" 'sell, deal in', a literary character which neither Kyōiku kanji nor Jōyō kanji includes. However, in kanbun texts it is relatively common to use a large amount of furigana—often there is an interest in "recovering" the readings used by people of the Heian or Nara periods, and since many kanji can be read either with on- or kun-yomi pronunciations in a kanbun text, the furigana can show at least one editor's opinion of how it may have been read.
