Nikaidō Tokitsuna

Nikaidō Tokitsuna (born c. 1280) was a samurai administrator of the late Kamakura and Nanbokuchō eras, the son of Nikaidō Moritsuna. He first served on the Kamakura shogunate's Council of State, then took Buddhist vows in 1311 under the name Gyōin.

In 1333 the Kenmu Restoration named him the first head of the Administrative Board of the Kamakura governor's office, and the Muromachi shogunate reappointed him to that post four times between 1346 and 1350. During the Kannō Disturbance he sided with Ashikaga Tadayoshi.
