This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular volleyball manga and anime series, 'Haikyu!!', comes a Nendoroid of the Shiratorizawa High School Volleyball Club's captain known as the undisputed champion - Wakatoshi Ushijima! He comes with three face plates including a standard confident expression, an expression showing his confidence during a match as well as a smiling expression with closed eyes.
The Nendoroid allows you to recreate a number of memorable scenes from the series and also comes with a volleyball as well as a special base made in the image of a volleyball court. He also comes with effect parts to display him hitting the volleyball with great force for action poses, as well as a water bottle for some more relaxed poses. Be sure to display him with the previously released characters in the series and enjoy all sorts of different situations in Nendoroid size!
