This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular volleyball manga series with an equally popular anime, "Haikyu!!", comes a Nendoroid of the Karasuno High School Volleyball Club's captain and reliable receiver - Daichi Sawamura! He comes with three face plates including a standard expression, a serious expression for when he is in a match as well as the malicious smile he had when he shook hands with Nekoma High's volleyball team's captain Kuroo.
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 the Karasuno High School Volleyball Club Support Flag that reads "Jump!". Be sure to display him with the previously released characters in the series and enjoy all sorts of different situations in Nendoroid size!
