Along the same lines as the aforementioned Fascinating Repairmen, more short documentaries from Japan about crafting, which is apparently a genre. There seem to be dozens if not hundreds of these that have been uploaded to YouTube by the Japan Science and Technology Agency. Apart from a few captions– in Japanese, obviously– the videos are all wordless and self-explanatory. The seven embedded here are the ones I’ve found most interesting so far (listed in ascending order of Japanese-ness, possibly): manufacturing marbles from recycled glass, sculpting and moulding shop mannequins, kendo (Japanese bamboo stick-fighting) armour, paper lanterns, dolls for the annual 雛祭りHinamatsuri (Doll Festival), realistic fishing lures, and creating food samples out of PVC and wax.
