Shun Amaguri is a character of Doraemon who first appeared in the episode "I've Got a Spare Fourth Dimensional Pocket".

Shun Amaguri is a famous celebrity. He had taken a year off from showbiz to rest at home, but occasionally receives requests for autographs. On a day Nobita and Shizuka came to visit him, he tells them about his frustration over the sudden appearance of trash in his storage room (which Nobita dumped), and gets Nobita’s help to clear it.

Shun Amaguri is taken from the Japanese actor Shun Oguri.
