This is a posable action figure from the figma series.
From the Good Smile Company website:
From the popular anime and manga series "Haikyu!!" comes a figma of Karasuno High School Volleyball Club's ultimate decoy, Shoyo Hinata!
The smooth yet posable figma joints allow you to act out a variety of different scenes.
A flexible plastic is used for important areas, allowing proportions to be kept without compromising posability.
He comes with three face plates including a calm and composed expression, a serious expression to pose him during a match as well as a lively smiling expression.
Accessories include a volleyball, net parts and a drink bottle to recreate various scenes from the court.
An articulated figma stand is included, which allows various poses to be taken.
