The Mōri clan (毛利氏) is a clan that has ties since the Heian period in Japan. They survived the Warring States period and are still active to this day. In the Samurai Warriors series, they are represented with orange.

The three stars in their family crest references three stars within Orion's constellation. In Chinese culture, these three stars represent three generals. This particular aspect of mythology carried over in Japan, in which the general group of stars was known as the "warrior's star". The single character that graces the three stars is believed to symbolize the ancient Mōri clan's founder, who was said to have been Emperor Heizei's bastard child and a lost candidate as the land's imperial prince. It remains as a lasting mark of the Mōri's ties to royalty.

Omodaga, also known as "Victory Grass" (勝ち草) in the Warring States period, was considered a good luck charm and was favored by soldiers since the early Heian era. The Mōri are said to use it due to a far-fetched yet interesting tale regarding Motonari. One year, while he was at war, he crossed a river. He stopped to watch a dragonfly land on a full grown omodaga and admired the beautiful sight. While he watched them and felt moved by the simple joys in nature, he happened to see a breech in the enemy lines. Motonari ordered his troops to advance and they claimed a resounding victory. Hence, the omodaga was said to have been assigned as a code of arms in their clan.

Other Figures[]

  • Aiō Mototsuna - Hiromoto's third son, Okimoto and Motonari's younger half brother. Said to have carried the nickname "Ima Yoshitsune" and was fabled to be on good terms with Motonari. When Kōmatsumaru died, Mototsuna planned to use his daughter-in-law as a means to gain leadership of the clan. He died while reportedly planning to assassinate Motonari, supposedly being killed by the latter before his plans could come to pass.
  • Kita Narikatsu - Hiromoto's fourth son, Okimoto and Motonari's younger half brother. Due to his mother's low status, he became a priest at Jorakuji. Eventually, he returned to a secular life and was introduced into the Kita clan, family vassals of the Mōri. Since Narikatsu had no children, Motonari was going to offer his second son to his brother. However, the child was ultimately sent to the Kikkawa family to compensate for Kikkawa Okitsune's abolishment. Narikatsu died without leaving behind an heir.
  • Misuke Motoshige - Hiromoto's fifth known son, Okimoto and Motonari's half brother. He is quoted from shrines and other sources to have existed, but it remains unclear if he was born before or after Motonari. Two popular beliefs regarding his origin is that he is either a bastard child or Hiromoto's grandson. Not much is currently known about him.
  • Kikkawa Motoharu (Mōri Motoharu)
  • Kobayakawa Takakage (Mōri Tokujumaru)
  • Hoida Motokiyo (Mōri Motokiyo) - Motonari's fourth son. Since Motonari already had three sons of noble lineage, he was said to have handled the rest of his children rather roughly. Motokiyo was born when his father was 50, and he was hastily married away to the Hoida family to strengthen their naval forces. Even though he was pushed into the background, he served bravely in many of his family's campaigns. Terumoto grew fond of his son, Hidemoto, and established them once more with the Mōri name.
  • Sugimori Motoaki (Mōri Motoaki) - Motonari's fifth son. To vitalize his ties with the childless Sugimori Takayasu, Motonari assigned Motoaki to be his vassal's adopted child. When Motonari's ties with Takayasu disappeared during the Izumo campaigns, he was then renamed under his biological family name.
  • Izuha Mototomo - Motonari's sixth son who was adopted by the then childless Izuha Motosuke at an early age. Motosuke planned to make him his successor but Mototomo died a premature death at age 17. Motosuke mourned his passing and enshrined him under his family name with utmost respect.
  • Amano Motomasa (Mōri Motomasa) - Motonari's seventh son who was said to have been a proud warrior and faithful to his father, even if he was a sloppy dresser. He was sent to the Amano clan at an early age to quell disputes regarding a family successor. He participated in several battles including Siege of Kōzuki Castle and The Battle of Sekigahara. Eventually reestablished himself under the Mōri name and started the Migita-Mōri clan.
  • Suetsugu Motoyasu (Mōri Motoyasu) - Motonari's eighth son. Inherits Motoaki's castle after his older brother's death. Prior to the Sekigahara conflict, he decided to leave Hidemoto to his own fate and led a group of followers to join the Siege of Ōtsu Castle. Returned to Osaka Castle and died in 1601.
  • Kobayakawa Fusamoto (Ota Mototsuna or Mōri Hidekane) - Motonari's ninth son. First adopted into the Ota clan but was later adopted by his older brother, Takakage. He was sent to Hideyoshi as a hostage and gained the Hidekane name. Appealed to Terumoto to join forces with Hideyoshi after the Komaki-Nagakute conflicts. Assisting in the Kyushu conflict, he married Ōtomo Sōrin's daughter and converted to Christianity. His baptized name was Simao Findenao. Participated in the Siege of Ōtsu Castle and resisted with the Tachibana family until their surrender. To disassociate himself from Hideaki's betrayal, he adopted the Mōri name once more. He died due to illness in 1601.
  • Ninomiya Naritoki - Motonari's illegitimate child (though some speculate that this is only a rumor).
  • Hidemoto - Motokiyo's son and Terumoto's adopted son. He is best known for his indecisiveness and inability to act at Sekigahara.


  • Fukuhara Hirotoshi's daughter - Hiromoto's first wife, Okimoto and Motonari's mother
  • Sugi no Ōkata - Hiromoto's second wife. Little is known about her but Motonari thought fondly of her loyalty to his father.
  • Takahashi Hisamitsu's daughter - Okimoto's wife
  • Myōkyū Fujin - Kikkawa Kunitsune's daughter, Motonari's first wife. Gave birth to Yōsetsu no Kata, Takamoto, Goryū no Tsubone, Motoharu, and Takakage. Motonari and his first three sons seemed to have loved her as they unabashedly held funeral rites for her and mourned for her.
  • Nomi no Ōkata - Motonari's second wife (also said to be his concubine), her real name is unknown. Gave birth to Motokiyo, Motomasa and Hidekane.
  • unknown maiden from Miyoshi clan - Motonari's concubine. Gave birth to Motoaki, Mototomo, and Motoyasu.

Forty-seven Ronin[]

Hidemoto's grandson, Tsunamoto, was involved with watching ten of the famous Forty-seven Ronin in his residence. He was ordered to do so after the ronins had achieved their goal. True to the typical attitude towards rebels, he labeled them as scoundrels and criminals. Once he realized that the Hosokawa clan had treated the ronins with respect, Tsunamoto reflected on his actions and strove to portray the ten warriors in a better light. A marker for the mansion these ronins once resided and other memorials for the ten still exists in Tokyo today. The following lists the ten ronin in question.
