Ishikawa Masamochi was born Nukaya ShichihÃÂ. According to the autobiographical Rokujuen Jihitsu Kirekiroku (å Â樹åÂÂèªçÂÂå¿Âæ´é²), he was born on the fourteenth day of the twelfth month of Hà Âreki 3 according to the traditional Japanese calendar (1753/4 in the Gregorian calendar).
He was the eighth child of the , Edo innkeeper Nukaya ShichihÃÂ, better known as the ukiyo-e master Ishikawa Toyonobu. His mother was Toyonobu's second wife, the younger sister of his first wife. According to Masamochi's autobiographical Towazu-gatari (ã¨ã¯ãÂÂãÂÂãÂÂãÂÂ), all of the children of his father's first wife died young.
He died on the 24th day of the third month of Bunsei 13 (1830). He was buried in the Kaya-dera (ãÂÂãÂÂ寺, official name æ£è¦Â寺 Shà Âkaku-ji) in Asakusa. His grave still exists, but the grave marker was destroyed in a fire.
Masamochi's real birth name was Nukaya Shichihà(ç³ è°·ä¸Âå µè¡Â). In his childhood he was known by the name Kiyonosuke (渠ä¹Âå©). He changed his name to Ishikawa Gorobà(ç³å·ÂäºÂéÂÂå µè¡Â) at one point.
His courtesy name was Shisà  (Ã¥ÂÂç¸). His kyà Âmei (çÂÂÃ¥ÂÂ, kyà Âka pen name) was Yadoya Meshimori (宿å±Â飯çÂÂ), a reference to his family business as innkeepers (宿屠yadoya). He used numerous art names, including Rokujuen (å Â樹åÂÂ), Gorà  Sannin (äºÂèÂÂ山人), Gyakuryo Shujin (éÂÂæ 主人) and Gajutsusai (è¾è¡ÂæÂÂ).
His posthumous dharma name is Rokuju-in Daiyo Gorà  Kyoshi (å Â樹é¢å°èªÂäºÂèÂÂ屠士).
Perhaps because of his father's connections in the world of art and culture, Masamochi first began his Japanese studies under and Chinese studies (kangaku) under Furuya Sekiyà  (å¤å±ÂæÂÂé½).
As a kokugaku scholar, his main research interest was The Tale of Genji, on which he regularly lectured. These lectures formed the basis of his commentary, Genchà « Yoteki, and his gago (é èªÂ, "elegant language") dictionary Gagen Shà «ran (é è¨ÂéÂÂ覧).
He first took up kyà Âka composition under , but in 1783 became a disciple of Yomo no Akara. The same year, his kyà Âka appeared in Kyà Âka-shi Saiken (çÂÂæÂÂ師細è¦Â; ed. ) as those of a disciple of Fuguri Tsurikata (æ®æ Âé£æ¹), and in Kyà Âka Shittariburi (çÂÂæÂÂç¥足æ¯) as those of a disciple of Yomo no Akara.
