Bizen Osafune Shuri no Suke Morimitsu is one of the famous smiths of the Oei period of the early Muromachi, known as the Oei San Mitsu. The other two of the three named are his father Moromitsu and his colleague and likely younger brother Yasumitsu. Together, these three smiths are considered the representative Bizen smiths of this time.

Kokan Nagayama writes that these three are "very famous, and excellent." Today there exist many highly rated swords from these smiths at the most prestigous levels, Juyo Bunkazai, Juyo Bijutsuhin and Kokuho (National Treasure). The three smiths together are considered to be the best swordsmiths active during their period.

Morimitsu traces his lineage back to one of the most renowned Bizen smiths, Kanemitsu, through his father Moromitsu, who learned from Kanemitsu's student Tomomitsu. Kanemitsu is one of the Masamune no Juttetsu (the Ten Disciples of Masamune), but it is currently disputed whether he learned directly from Masamune or was only partially influenced by the Soshu style which came into vogue at his time. Kanemitsu is thought to have made the sharpest nihonto, bar none, and his work was popular with generals and daimyo for this reason. They often carry names such as "The Stonecutter" which testify to their prowess.

After Kanemitsu's time, the Bizen tradition fell into a slow period of decline. The subsequent appearance of the Oei San Mitsu (Morimitsu in particular) is significant in reversing this decline bringing the Bizen tradition back to the fore. The two smiths Yasumitsu and Morimitsu are known to have worked together on pieces they have jointly signed, and these two smiths are recognized as O-wazamono, for a very great degree of sharpness on their works. Fujishiro states that in terms of swordmaking in general in Japan during the Oei period:
Individuals Yasumitsu and Morimitsu possessed superior technology and overwhelmed the others, and this is probably one of the facts contributing to the traditional story about the superiority of the Bizen swordsmiths. This activity of Yasumitsu and Morimitsu was after around Oei 15 or 16.

It is considered that the work of Morimitsu represents the pinnacle of nihonto artistry during his time period. Morimitsu also carries a very high rating for sharpness, O-wazamono, for highly superior cutting ability.
