I got lost in a random Tokyo neighborhood and a random guy came out, tapped my dude shoulders and showed my ugly ass where my Airbnb was. This was after the Uber driver walked me 1.5 blocks (leaving his car engine on with the keys inside) to show me where he thought it was. I went to a bar and the bartender snuck a umbrella in my arm when it rained, and told me if I got lost, to call him. And a random person, realizing I was born stupid, help me use a washing machine.
It's true. Once, when I was visiting Kyoto, I actually forgot how to eat, and a kind elderly man held me and tenderly bottle-fed me. I didn't even ask him to.
