Climbing between apartment balconies is easier in Japan cos they're so small and close together. I had a really tall neighbour (over 190cm) who lived next door to me, and he'd sometimes try to scare the crap out of me by climbing over to my balcony and knocking on the back sliding door!

I did try climbing over to his place once or twice, but at my diminutive 1.7m frame I wasn't game to do it too many times.
