Hōki no Kami Masayuki was the son of the second-generation Ijichi Masayoshi, a smith of the Ijichi house of Satsuma domain artisans, born in Kyōhō 18 (1733). He succeeded as the third generation and at first signed Masayoshi (正良), with works on record from about the Hōreki era; in Kansei 1 (1789), at the same moment that his elder townsman Oku Motohira was made Yamato no Kami, he received the court title Hōki no Kami, ceded the name Masayoshi to his heir, and changed his own name to Masayuki. He worked into great old age, dated and age-inscribed pieces surviving up to his eighty-fifth year, and died in Bunsei 1 to 2 (1818-1819) at eighty-six or eighty-seven. The published sources place him by a single recurring pairing that has held ever since. Together with Oku Motohira he is named one of the twin pillars of Satsuma shinshintō, the published commentary saying of him, in its own words, that with Oku Motohira he stands among 「薩摩新々刀中の双璧」[[c:1]], the twin pillars of Satsuma shinshintō. He is the one the same sources hold to have surpassed his forebears, celebrated as a smith who out-shone his master.

His characteristic hand is a broad, long, robust katana the published sources name his favored Sōshū-den, and which he himself called Sōshū-den, the commentary recording 「自から相州伝という」[[c:2]], that he himself called it so. The body is wide in mihaba, the kasane thick, the kissaki extended, the construction generally sturdy. Over it he tempers a shallow notare-toned gunome-midare into which he sets pointed togariba, the gunome with a pointed tendency being the feature the judges most often single out as his forte, deep in nioi with thick nie that is somewhat coarse and sprinkled on, ara-nie mixed. Through the ha run frequent sunagashi and long kinsuji, the streaming Satsuma nie-lines known as imozuru, the yam-vine. The pointed teeth and the running vine are the spine of his recognition, a Sōshū-den read in coarse nie rather than in clove-flower, and the published sources name its model directly, calling his manner one that 「相州伝, 就中, 志津に倣った作柄を得意としている」[[c:3]], a Sōshū-den excelling above all in imitation of Shizu.

The jigane is the constant beneath. It is a well-forged itame, often packed and mixed with mokume and nagare, carrying thick ji-nie and a dark chikei-like variant steel, on his finest pieces bright and clear. Over it the bōshi runs in midare-komi or straight, turning back in ko-maru or ō-maru, the point swept with hakikake and at times breaking into nie-kuzure. There is one feature the published sources raise as a kantei point on the tang itself. The nakago is almost always ubu, narrowed to a sword-shaped kengyō or iriyama-gata tip with katte-agari file marks, the long signature cut boldly with a thick chisel and frequently carrying his age; and on the great majority of his blades he carves a bō-hi, a habit the sources tie to his wide mihaba and thick kasane, the groove omitted only when a blade is of more standard width.

His record divides by name and by period. The earlier work, signed Masayoshi before the title and the change of name, is read as a quieter register before the full vigorous Sōshū hand emerges: a ko-notare mixed with gunome, ashi and hotsure entering, thick nie with areas of ara-nie and sunagashi, the bōshi tending to ō-maru with the point breaking down in nie-kuzure. The forging beneath that early temper is already the Satsuma steel he carries into his prime, a wide itame with conspicuous ō-itame and flowing grain, so the Masayoshi face is the same hand held quieter rather than a separate school. Among his dated pieces the inscriptions run beyond the date: one katana of Kansei 12 (1800) carries a Kōshin-faith inscription, that a sword forged in a year when the Kōshin day falls seven times secures lasting martial fortune, a text the sources call unusual, and another bears the deity invocation 「南無八幡大菩薩」 carved on the tang.

What sets him within his province is exactly the pairing the judges name and the manner they return to. He is read first against his elder townsman Motohira, the two held together as the twin pillars of Satsuma shinshintō, the one the Oku house and the other the Ijichi, raised to their court titles in the same year. His own grounded traits are what distinguish him, not a borrowed comparison: the broad, robust sugata, the pointed togariba in a deep-nioi gunome-midare, the coarse ara-nie feeding a hakikake bōshi, and the running imozuru. The published sources measure his refinement against that very vine, praising one of his Shimazu-held katana precisely because the 「芋蔓風の金筋・沸筋」[[c:4]], the vine-like kinsuji and nie-suji, do not crowd it, the absence lending it higher grace. He stands at the head of the Ijichi line, the hand by which a Satsuma shinshintō blade of his descent is read.

For the collector he is one of the great names of late Satsuma, and Fujishiro grades him Jō saku. He has no National Treasures and no Important Cultural Properties; his record on the modern designation tiers runs through the Jūyō rank, where twenty-eight of his works are held, all ubu and signed across a working life from the Kansei years to near his death. The provenance among them is distinguished and local to his domain: one katana descends from the Satsuma lord, the Shimazu house, kept as a reserve sword of Tsurumaru castle, and another comes down through the Kabayama house, a Shimazu branch, with a Satsuma koshirae whose fuchi-gashira and kojiri are by Masayuki's own hand. Most designated blades, including those in private hands, are held rather than traded, and a fine signed Masayuki of his characteristic Sōshū-den comes to market only from time to time and with patience. His work is, comparatively, among the more findable of the first-rank shinshintō masters, more so than the locked heritage of the older traditions, but a dated, age-inscribed katana in his full vigorous manner remains a substantial acquisition, a document of how Satsuma forging reached its late summit beside Oku Motohira.
