This item is an injection-plastic passenger car kit.
"Ita-sha" literally means "pain car" in Japanese, suggesting that these cars garishly decorated with colorful anime character graphics are embarrassingly painful to look at or ride in. A bit harsh, perhaps, but there you have it! Another take on the name is that it's riffing on the similar sound of the nickname for Italian cars, also pronounced "Ita-sha" but with the kana for Italy's "Ita" in place of the kanji for pain (also pronounced "ita" in this combination). "Sha" in both cases means "car."
The Ita-sha phenomenon has spread to trucks! This nice big 4-ton wing truck kit features graphics from the popular "K-On!" anime. The decals for the graphics are particularly well done, featuring image fidelity not often seen in automotive kits. Aside from the decals, this is Aoshima's standard kit of a 4-ton wing truck. Figures not included!
