Wachi

The Wachi were local lords based at Nantenyama Castle in Kisa, Bingo province. Wachi Toyosato joined Mōri Motonari against the Takahashi in 1529, while his son Masaharu served the Yamana lords of Bingo.

Masaharu fought alongside the Mōri at Itsukushima in 1555 and came increasingly under their influence. In 1563 Mōri Takamoto died suddenly after visiting Masaharu, an episode that later became entangled in suspicions over his death.
