Upuaza Touryou likes to have fun with Amazon boxes. He previously built a model temple out of them. So it only makes sense that now he has built a tank. An amazing, remote controlled tank of a Type 97 Chi-Ha, which was used by the Imperial Japanese Army in the late 1930s and early 1940s.
Despite only costing him 1,500 yen (~$15 USD), it took two months to complete. It has tons of nice detail and is quality made all the way. The man is a wizard with an X-Acto knife. A paper model of this quality is impressive enough, but this thing is actually remote controlled and moves around.
This is the best way ever to recycle those Amazon boxes.
