Weird and not so weird inventions in Japan

18 Turning train seats? They existed for decades. Not so weird, in my opinion.
14 Diagonal crossings are found in suburbs as well. They cut short the red light time for the car traffic. For pedestrians, it’s cool because they won’t have to cross twice.
7 Australian visitors were impressed.
2 They come with small keys, so that your umbrella won’t get stolen.

Some of the inventions mentioned here are outright weird and I haven’t seen them myself.
