Iwaki still has some odd slopes in the floor where the floor shifted upwards 10 cm or so (blog post with a picture upcoming). assembly line and to be managed through TPS (Toyota production system) by which each assembly line help create final product in form of vehicle. Toyota has successfully exported its culture to its overseas plants (NUMMI being the first famous example, first chapter of my book). Their first car based on this TNGA is the 2015 fourth-generation-model Toyota Prius. The fully-assembled vehicle is subjected to a strict quality check in the final inspection process and is then shipped as a finished automobile. Each small blue box below represents one station along the line or, in most cases, approximately one worker (not counting team and group leaders). Asia’s culture is difference from Western’s culture, this is the reason why Toyota has much more variant/models then any competitors. Below are two still images from a video at the Toyota Kaikan from the Tsutsumi plant. However, there is a lot lost in translation from the original Japanese name 伸縮自在な組立ライン (Shinshuku jizai na kumitate rain).
