Tsuyu Nights — Tokyo Rain Radio with a Live JST Clock

The June rains of Tokyo on umbrellas and vending-machine light, timed to the second on Japan Standard Time.

Tokyo's rainy season, tsuyu, turns the city into a study of transparencies: plastic umbrellas by the million, konbini glass fogged at the edges, puddles doubling the signage. The rain itself is polite but relentless — a sound the whole city works, commutes and sleeps inside for weeks.

We mix it from street level: rain on vinyl umbrellas and station roofs, the underwater whoosh of a passing bus, a pedestrian crossing's distant chirp surfacing rarely, like a memory. The clock keeps exact JST — Japan never shifts its clocks — and the scene follows Tokyo's light from pale humid morning to the long neon-smeared night.

Salarymen nap to this on trains; you can use it for gentler purposes — sleep, focus, or the specific nostalgia of waiting out a downpour under an awning in Nakameguro with nowhere better to be.
