Akagawa Motoyasu
- Died: 1567
- Title: Sakyô
Motoyasu was a son of Akagawa Fusanobu. He became the head of the Akagawa following the death of his elder brother Narihide in battle around 1523. He was a notable retainer of Môri Motonari and was named one of his '18 Generals'. He became a close retainer of Môri Takamoto and was consulted by him on most matters. After the sudden death of Môri Takamoto in 1563 he was confined to his home under suspicion and was later made to commit suicide along with his adopted son Matasaburou. Akagawa Nobuyuki, a nephew, was named as heir to his house. Motoyasu’s part, if any, in Takamoto’s suspicious passing is unclear. Akagawa Nobuyuki, a nephew, was named as heir to his house.
