This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular anime "Hetalia The World Twinkle" comes a Nendoroid of Japan! He comes with both a modest standard expression as well as an impassioned expression for when he talks about food!
Optional parts include the case for his bamboo sword, his pet dog Pochi-kun as well as some Japanese rice for him to eat and talk about! He also features a special round base decorated with cherry blossoms to bring out the Japanese atmosphere! Be sure to add the shy and somewhat mysterious Japan to your collection!
