It seems like such an obvious idea, but apparently no one had ever thought of it before (at least, not that we know).
Some marketing genius in the small hot spring town of Yumura Hot Springs in Hyogo Prefecture came up the idea of selling tourists local sake in bamboo carafes, which they heat up in hot spring water while enjoying a nice stress-busting soak.
Sounds nice indeed ... Just be careful when you stand up!
