This is a Japanese-language book or magazine about cars and/or car modeling.
"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! This new, all-color magazine is dedicated to the Ita-sha phenomenon, introducing you to the "beautiful world of Ita-sha"! All text is in Japanese.
