Summer in Japan is utter balls.
BALLS.
Hot, humid, even when it rains, it stays hot. It's like being stuck in someone's tighty-whiteys, right between the drenched cotton fabric and their hairy, ill-kept sac.
When I go into any given store, the A/C is cranked to artic temperatures, freezing the sweat immediately to my skin. Then, then next time I go outside, and begin to sweat again, the new sweat strains against the shell of outer, frozen sweat to double down on the overall moistness.
Being in the USA last year, and working in the SF/Bay Area, I was so, so happy each day to walk outside into the stark sun, the dry air, and realize for the first time in 10 years that summer isn't a four month exercise in endurance.
