Miike Denta Mitsuyo was a swordsmith who resided at Miike in Chikugo Province. The founder is identified as a renowned master of the late Heian period, whose representative work is the celebrated meibutsu Odenta, transmitted in the Maeda family. "Mitsuyo" was not a single individual: the same name was successively borne from the Kamakura period into the Muromachi period. Across all eras, signed works are exceedingly few. One branch of later smiths relocated to Aki Province, as documented by dated tanto from Meitoku 2 (1391). The school's traditional style effectively comes to an end with the Nanbokucho period; in the Muromachi period, little of its former character remains.

From the time of the Odenta onward, the Miike style shares traits common to early Kyushu workmanship. The forging is itame that flows conspicuously, at times inclining toward masame, with ji-nie presenting a "sticky" texture; shirake-utsuri (whitish utsuri) is characteristic. The hamon is predominantly suguha-cho in ko-nie-deki, with a tendency toward hotsure and elements of kuichigai-ba, showing a nioiguchi with a shizumi (subdued) inclination. The boshi runs straight and returns in ko-maru. An individuality of the school can be observed in its preference for carving wide, comparatively shallow bo-hi, often accompanied by auxiliary soe-hi, executed in kaki-nagashi or kaki-toshi. The blade form characteristically shows a wide mihaba with a compact kissaki forming an ikubi (boar's-neck) appearance.

The NBTHK characterizes even later-generation works as preserving the traditional manner in both ji and ha, and notes the school's stylistic continuity from the Heian through the Nanbokucho period. Across the corpus, the Miike school occupies a distinctive position among early Kyushu traditions, unified by the flowing grain, subdued nioiguchi, and broad sculptural grooves that define its identity from the time of its celebrated founder onward.
