Mōri's Two Rivers Strong and fearless, Motoharu participated in many battles such as Miyajima and Nunobeyama, bolstering his reputation as a valiant commander. There are claims that he won 64 of 76 battles throughout his entire life. According to the Meisho Genko Roku, his brawn was often contrasted with Kobayakawa Takakage's intellect back in their youth. This inspired Mori Motonari to make effective use of their differences in personality by relegating Motoharu to the front lines while leaving Takakage to provide strategic support from the rear. Although Motoharu heavily contributed to the Mōri's military growth, he was familiar with literature and even transcribed a series of books called the Taiheki during the siege of Gassantoda Castle. They were both together pillars of the Mōri forces and were known as "Mōri's Two Rivers" (Mōri Ryōkawa, 毛利両川). After the death of Mōri Motonari in 1571, "Mōri's Two Rivers" (Kobayakawa Takakage and Kikkawa Motoharu) became more important as assistants to Mōri Terumoto against the remnants of their enemies, the Ōtomo clan (大友氏), Amako clan (尼子氏), and Ōuchi clan (大内氏).
