Gekko-in

• Other Names: Okiya-no-kata, Teruko, Sakyô-no-tsubone
• Japanese: 月光院 (Gekkou-in)

Gekkô-in was a daughter of Shôda Gentetsu Akinori, consort of Shogun Tokugawa Ienobu, and mother of Shogun Tokugawa Ietsugu.

She was the third of Ienobu's concubines to give him a son, after Okomu no kata and Osume no kata. However, these two previous boys died at the ages of two months and two years, respectively. Gekkô-in's son Nabematsu survived to be named shogun at the age of three, upon Ienobu's death in 1712.
