How are you going to hide yourself when you’re in trouble? I think this stealth tactics in Japan might help you to escape from your enemy. The modern ninja against crime, these are created by fashion designer Aya Tsukioka who has conjured up some neat transforming clothes/accessories to deceive potential criminals. The vending machine and the public phone disguised is obvious while the manhole handbag is used to keep the contents of the handbag safe. But if your enemy is thirsty and they’ll go for the vending machine, you gotta pray hard for that time 
why would Japanese invent such things? It’s totally useless!
